Sistem tanda tangan digital telah banyak dimanfaatkan terutama untuk kegiatan persetujuan dokumen selama pandemi COVID-19 di Indonesia. Penelitian ini bertujuan untuk mengetahui faktor-faktor dari dimensi sustainability yang mempengaruhi keberlanjutan dalam menggunakan sistem tanda tangan digital berdasarkan metode pendekatan AHP. Penelitian ini menggunakan metode AHP karena metode ini mampu menyelesaikan persoalan dalam suatu kerangka berpikir yang terorganisir sehingga dapat mengambil keputusan secara efektif dan akurat terhadap suatu persoalan dalam penelitian. Hasil penelitian menunjukkan bahwa sub-kriteria continuous improvement dari dimensi ekonomi menjadi prioritas utama yang menjadi penunjang dalam keberlanjutan bisnis penyedia tanda tangan digital. Selanjutnya, melakukan analisis pemilihan platform tanda tangan digital antara PrivyID, DigiSign, dan Manual Input. Berdasarkan hasil perhitungan terhadap tiga alternatif menghasilkan platform DigiSign yang paling unggul dibandingkan dengan platform PrivyID dan Manual Input. Hasil tersebut sejalan dengan komitmen dari platform DigiSign yang memberikan kemudahan bagi pengguna agar dapat memeriksa dokumen yang tertunda dengan cepat, menandatangani dokumen dengan tingkat keamanan yang tinggi dan enkripsi berstandar Internasional, serta dapat melacak status dokumen dengan mudah. Sedangkan tanda tangan elektronik yang dilakukan dengan cara Manual Input memiliki kelemahan yang sangat kritikal, dimana tanda tangan elektronik tersebut tidak terenkripsi sehingga tidak mampu untuk melindungi dokumen dari pencurian data identitas atau entitas perusahaan oleh pihak yang tidak bertanggung jawab. Abstract             The digital signature system has been widely used, especially for document approval activities during the COVID-19 pandemic in Indonesia. This study aims to determine the factors of the sustainability dimension that affect sustainability in using a digital signature system based on the AHP approach. This study uses the AHP method because this method is able to solve problems in an organized framework so that it can take a decisions effectively and accurately on a research problem. The results of this study indicate that the sub-criteria for continuous improvement from the economic dimension is the main priority that supports the sustainability of the digital signature provider business. Furthermore, analyze the selection of digital signature platforms between PrivyID, DigiSign, and Manual Input. Based on the results of the calculation of the three alternatives, the DigiSign platform is the most superior compared to the PrivyID platform and Manual Input. This results are in line with the commitment of the DigiSign platform which makes it easy for users to quickly check pending documents, sign the documents with a high level of security and International standard encryption, and easy to tracking the document status. Meanwhile, electronic signatures made by Manual Input have a very critical weakness, where the electronic signature is not encrypted so it is unable to protect documents from theft of identity data or corporate entities by irresponsible parties.

The third stage of the NIST PQC competition is currently underway, which aims to create new post-quantum standards in cryptography. The vast majority of finalists are representatives of lattice-based cryptography. Electronic signatures include the CRYSTALS-Dilithium schemes. This paper investigates the feasibility of using AVX512 to optimize software implementations of NIST PQC finalists among electronic signatures on algebraic lattices. Since the most expensive operation in such schemes is the multiplication of polynomials, the main attention is paid to the optimization of this operation. In particular, the method of realization of theoretical and numerical transformation using AVX512 for electronic signature schemes CRYSTALS-Dilithium is presented in the work. The increase in speed is shown in comparison with the reference optimized author 's implementations.

Az elektronikus aláírás (electronic signature) fogalmát a jog definiálta elsőként. A fogalom konzisztens elterjedését nem segíti, hogy értelmezése számos átalakuláson ment keresztül, használata során keverednek a digitális aláírás (digital signature), az azonosítás (identification), a hitelesítés (authentication) és a feljogosítás (authorization), valamint a bizalom (trust, reliance), hitelesség, szavahihetőség (trustworthiness) fogalmak. Az elektronikus aláírásnak számos aspektusa jelent meg a jogalkotási és a jogalkalmazási területeken, például használható fokozott biztonságú elektronikus aláírás (advanced electronic signature) vagy minősített elektronikus aláírás (qualified electronic signature) a normál elektronikus aláírásokon túl. A fogalomrendszer bonyolultsága szintén nem kedvez a tömeges használatnak, azonban a fogalmak és követelmények ismerete nélkül nehezen eldönthető kérdés bizonyos esetekben, hogy használható-e az adott szolgáltatás teljes bizonyító erejű magánokirat vagy közokirat létrehozására vagy sem. A tanulmány az elektronikus aláíráshoz kapcsolódó fogalmak kialakulásának historikus vizsgálatát tűzte ki célul, amely révén átfogó kép alakítható ki a napjainkban használatos fogalmak jelentéséről és értelmezéséről. Ez a digitális világban alapvető fontosságúnak tűnik. --- The Emergence and Evolution of the Conceptual Framework of Electronic Signatures The concept of the electronic signature was used for the first time by legislators. Consistent use of this concept is not helped by the fact that its interpretation has undergone many changes. Related words – digital signature, identification, authentication, authorization, trust, reliance and trustworthiness – are used interchangeably. Many aspects of the electronic signature have appeared in legislation (especially in creating and applying laws), for instance; advanced and qualified signatures may be used in addition to normal signatures. The complexity of this concept is not helped by the wide usage of electronic signatures; however, without knowing concepts and legal consequences, it is hard to decide whether a given service can be used for creating public or private documents with full probative force or not. It is argued that knowing concepts and legal effects of electronic signatures seems to be essential in the digital world.

The article deals with the problems of the practice of obtaining changes and using an electronic signature (EP) by entrepreneurs in their activities, specifies the normative legal acts regulating the procedure for obtaining an electronic signature by relevant persons and submitting the necessary documents to the certification centers for obtaining it, specifies the types of EP — simple and enhanced, the procedure for using a simple unqualified and enhanced qualified signature. The concept of an electronic signature is defined in accordance with the law. The information contained in the item instance is described: the signature of the person who signed the document, the date and time of signing, its authority and relation to the data being signed, technical information, information for additional signature verification mechanisms, comments, files, a graphic image of the handwritten signature, and other functionally required data. The practice of judicial authorities is analyzed and certain problems of application and use of electronic signatures by legal entities and individuals are identified. We consider the authorities that issue qualified and unqualified certificates of electronic signatures on the territory of the Russian Federation, as well as the procedure for producing certificates for EP keys and their validity period. The reasons for the production of an item instance by certification centers (registration centers) and the package of required documents, depending on the status of the applicant, are set out. The role of trading platforms is indicated. The article considers the need to systematize legislative acts, develop a universal digital signature, and create terminals for sending electronic documents to regulatory authorities.

The article is devoted to the study and research of the properties of code-based cryptosystems. They provide a high level of security even in the conditions of quantum cryptographic analysis, i.e. belong to the new generation of cryptosystems for post-quantum application. The main disadvantage of the known code-based digital signature schemes is the long time to generate a signature. This is due to the large number of attempts to decode a randomly generated vector (which is interpreted as a syndrome vector). The high complexity of such a procedure requires the search for new mechanisms and algorithms that would accelerate the formation of code-base electronic signatures. The article presents the results of two research vectors. First, we propose a new code-based digital signature scheme on the use of a one-way function from the classical McEliece cryptosystem and not only provides a proper level of resistance to classical cryptanalysis and cryptanalysis using quantum computers, but also, compared to known alternatives, provides protection against special types of attacks, such as simultaneous counterfeit attacks. Quantitative estimates of the reliability and speed of the new cryptographic algorithm, which were obtained by experimental verification on the BCH codes, are also given. The second vector of research concerns the study of a new direction, which is associated with the modification of the decoder by artificially increasing the corrective code ability. Thanks to the improved decoder scheme, we can significantly reduce the generation time of signatures. The paper confirms the effectiveness of the proposed decoder modification in the implementation of a new digital signature scheme in comparison with the classic Peterson-Gorenstein-Zierler decoder in the context of comparing the speed of signature formation and the number of required decoding attempts.

Thanks to modern software, production efficiency can be improved several times. At the same time, the use of software related to documentation entails the ambiguity in the issue of coordination and approval of documents requiring verification. Thus, the system implemented to minimize paper workflow, by default, does not allow to sign it and / or send it for review for approval and other decisions. This paper proves the possibility of solving this problem by introducing an electronic signature in the enterprise. Analysis of the enlarged model of the enterprise allows you to determine the scope of electronic signature in industrial processes. Presents the parameters of the electronic signature, as well as the algorithm for the selection of parameters with justification for the choice of each of them. Provides information on the certification center, necessary for the implementation and maintenance of electronic signatures in a stable state. The practical implementation of the main actions with an electronic signature is shown.

This research will discuss and examine the importance of readiness for comprehensive regulations that function to strictly regulate the protection of personal data in using electronic signatures used in online buying and selling transactions. This research is legal research prepared using normative legal research methods. This research shows that the electronic signature in online buying and selling transactions is a legal term derived from a digital signature that functions to authenticate and verify a person's data that makes it electronically or online as a digital form of user identity, as well as proof of approval of an agreement on the transaction online as a form of prevention against cyber crime. Electronic signatures need to be considered where the government can prioritize ratifying this regulation to provide security guarantees for the protection of personal data when the owner of the electronic signature uses it to verify and validate an agreement contract in online transactions. The protection in question is a rule which regulates data sovereignty, rights, and obligations of the parties, along with criminal and civil sanctions to prevent misuse of personal data.

Signing documents is one of the most general requirements in our daily lives, including routines in Public Administration. After significant development of e-Administration, the question arose as to how the clients can sign documents electronically. The European Union legislated this question by the Regulation (EU) No. 910/2014 of the European Parliament and of the Council of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC. This Regulation (henceforward: eIDAS) gives a technologyneutral and high-level framework for using electronic signatures in the EU, it refers several implementing acts and standards, records applicable concepts and definitions, and declares several obligations for all Member States. The Regulation does not contain strong provisions for advanced electronic signature, but it defines four requirements for it. All electronic signatures which fulfil these four requirements have to be considered as advanced electronic signatures. In most of the cases, creating an advanced signature is easier and more cost-effective than creating a qualified signature, therefore it may be an alternative solution for signing documents in Public Administration also. This paper intends to summarize the relating legal environment and it demonstrates an implemented solution of advanced biometric signature in the private sector. Finally, we discuss the technical conditions of the applicability of advanced biometric electronic signature in Public Administration by discovering similarities and differences of application and acceptability.

HDL-level design offers important advantages for the application of watermarking to IP cores, but its complexity also requires tools automating these watermarking algorithms. A new tool for signature distribution through combinational logic is proposed in this work. IPP@HDL, a previously proposed high-level watermarking technique, has been employed for evaluating the tool. IPP@HDL relies on spreading the bits of a digital signature at the HDL design level using combinational logic included within the original system. The development of this new tool for the signature distribution has not only extended and eased the applicability of this IPP technique, but it has also improved the signature hosting process itself. Three algorithms were studied in order to develop this automated tool. The selection of a cost function determines the best hosting solutions in terms of area and performance penalties on the IP core to protect. An 1D-DWT core and MD5 and SHA1 digital signatures were used in order to illustrate the benefits of the new tool and its optimization related to the extraction logic resources. Among the proposed algorithms, the alternative based on simulated annealing reduces the additional resources while maintaining an acceptable computation time and also saving designer effort and time.
