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.

Document file is a means of transforming information from one person to another or from a group to another. The development of computerized technology has greatly increased. Document files are very vulnerable to fraud, eavesdropping or data theft by irresponsible parties. In order to maintain the security of document files, this can be done by using cryptographic techniques. Cryptography is the science of keeping data secure. Cryptography is one of the data security methods that can be used to maintain data authenticity, data confidentiality, and the authenticity of data transmission. SHA, which stands for Secure Hash Algorithm, is a standard hash function published by NIST (National Institute of Standards and Technology), (NIST, 1995a). This study will use the SHA-1 method to secure the authenticity of document files, document confidentiality, document integrity, and document authentication. This study describes the security process for detecting the authenticity of document files using the SHA-1 method in the form of detection so that confidential documents sent via public telecommunications cannot be changed or modified by unauthorized persons or unauthorized persons. This is done as an effort to minimize acts of fraud, hoaxes, or misuse of document files.

Verifiable Encryption

This chapter presents a new simple scheme for verifiable encryption of elliptic curve digital signature algorithm (ECDSA). The protocol we present is an adjudicated protocol, that is, the trusted third party (TTP) takes part in the protocol only when there is a dispute. This scheme can be used to build efficient fair exchanges and certified email protocols. In this paper we also present the implementation issues. We present a new algorithm for multiplying two 2n bits palindromic polynomials modulo xp–1 for prime p = 2n + 1 for the concept defined in Blake, Roth, and Seroussi (1998), and it is compared with the Sunar-Koc parallel multiplier given in Sunar and Koc (2001).

Digital Signature Algorithm

IoT (Internet of Things) is regarded as a diversified science and utilization with uncommon risks and opportunities of business. So, in this article, a digital signature mobile application (SignOn) is presented where, it provides a cloud based digital signature with a high security to sustain with the growth of IoT and the speed of the life. Different algorithms were utilized to accomplish the integrity of the documents, authenticate users with their unique signatures, and encrypt their documents in order to provide the best adopted solution for cloud-based signature in the field of IoT. Where, ECDSA (Elliptic Curve Digital Signature Algorithm) is utilized to ensure the message source, Hash function (SHA-512) is used to detect all information variations, and AES (Advanced Encryption Standard) is utilized for more security. SignOn is considered as a legal obligated way of signing contracts and documents, keeping the data in electronic form in a secure cloud environment and shortens the duration of the signing process. Whereas, it allows the user to sign electronic documents and then, the verifier can validate the produced signature.

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.
