Data security is a very important compilation using cloud computing; one of the research that is running and using cloud technology as a means of storage is G-Connect. One of the developments made by the G-Connect project is about data security; most of the problems verification of the data sent. In previous studies, Keccak and RSA algorithms have implemented for data verification needs. But after a literature study of other algorithms that can make digital signatures, we found what is meant by an algorithm that is better than RSA in rectangular speeds, namely Digital Signature Algorithm (DSA).DSA is one of the key algorithms used for digital signatures, but because DSA still uses Secure Hash Algorithm (SHA-1) as an algorithm for hashes, DSA rarely used for data security purposes, so Keccak is used instead of the hash algorithm on DSA. Now, Keccak become the standard for the new SHA-3 hash function algorithm. Because of the above problems, the focus of this research is about data verification using Keccak and DSA. The results of the research are proven that Keccak can run on DSA work system, obtained a comparison of execution time process between DSA and RSA where both use Keccak.

The Vehicular Ad-Hoc Network (VANET) is a liberality vehicle acts as remote switch or node in a cellular system. The VANET is much reasonable because of the single framework attributes agree to the system to be unbolted to metro. In this paper, we propose a Secure Hash Algorithm (SHA-1) to make an interesting key to every message. Likewise, prescribe capable and reasonable alias convention with prohibitive disconnection propagation. We set forward prime pseudonyms reasonably make a long time cycle that are worn to interact with semi-confided in experts and alternate pseudonyms with a minor lifetime which are utilized to talk with different nodes. Likewise, suggestion in the digital signature utilized in VANET is the basic, ECEDS (Elliptic Curve Encryption and Digital Signature). ECEDS enrich with system security by using a digital signature for the messages actually communicated with the system.

Tanda tangan manual masih diterapkan di setiap tingkatan organisasi, lembaga, korporasi, dan pemerintahan. Di Universitas Mercu Buana pengajuan usulan Hibah Dikti juga masih mewajibkan dosen melakukan pengesahan proposal dengan meminta tanda tangan ketua program studi, dekan, dan kepala pusat penelitian atau kepala pusat pengabdian kepada  masyarakat. Padahal tanda tangan manual ini sangat mudah dimanipulasi ketika pihak yang perlu dimintai tanda tangan tidak berada di tempat. Riset ini untuk menerapkan digital signature dalam pengesahan proposal Hibah Dikti menggunakan Secure Hash Algorithm (SHA) melalui sistem informasi berbasis website Simlitabmas Dikti yang cepat dan terjamin otentikasinya. Pada saat pembuatan aplikasi, sistem pengesahan proposal Hibah Dikti ini menggunakan codeigniter untuk backend sistem dan bootstrap untuk fontend yang menarik.

Digital signature merupakan suatu teknologi digital yang dapat disipkan pada suatu dokumen untuk menjaga otentifikasinya. Peneltian ini tertujuan menerapkan digital signature untuk menguji keutuhan dan otentikasi dokumen sertifikat tanah digital, serta dapat mendeteksi perubahan dokumen sertifikat tanah digital dari hasil manipulasi oleh orang yang tidak berhak. Salah satu cara untuk melakukan digital signature pada dokumen sertifikat tanah digital yaitu dengan menggunakan fungsi hash. Algoritma hash yang digunakan dalam penelitian adalah Secure Hash Algorithm-256 (SHA-256), sedangkan algoritma kunci publik yang digunakan adalah algoritma Rivest-Shamir-Adleman (RSA). Berdasarkan hasil pengujian yang telah dilakukan, dapat disimpulkan bahwa mengimplementasikan digital signature menggunakan fungsi hash algoritma SHA-256 dan algoritma RSA dapat memberikan layanan keamanan otentikasi dokumen pada sertifikat tanah digital sehingga dapat mencegah terjadinya pemalsuan dan manipulasi dokumen oleh orang yang tidak berhak

In this paper, an effective framework for chaotic encryption based on a three-dimensional logistic map is presented together with secure hash algorithm-3 (SHA-3) and electrocardiograph (ECG) signal. Following the analysis of the drawbacks, namely, fixed key and low sensitivity, of some current algorithms, this work tries to solve these two problems and includes two contributions: (1) removal of the phenomenon of summation invariance in a plain-image, for which SHA-3 is proposed to calculate the hash value for the plain-image, with the results being employed to influence the initial keys for chaotic map; (2) resolution of the problem of fixed key by using an ECG signal, that can be different for different subjects or different for same subject at different times. The Wolf algorithm is employed to produce all the control parameters and initial keys in the proposed encryption method. It is believed that combining with the classical architecture of permutation-diffusion, the summation invariance in the plain-image and shortcoming of a fixed key will be avoided in our algorithm. Furthermore, the experimental results and security analysis show that the proposed encryption algorithm can achieve confidentiality.
