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 issue of securing Telecommand data communications in civil and commercial space missions, by means of properly located security services and primitives, has been debated within the Security Working Group of the ConsultativeCommittee for Space Data Systems since several months. In the context of Telecommand transmissions, that can be vital in determining a successful operational behavior of a space system, the interest is mainly focused on authentication, more than encryption. The object of this paper is to investigate, under the perspective of computational overhead, the possible applicability of a standard scheme, Digital Signature Algorithm with SHA-1, to the authentication of Telecommand data structures, andto discuss the pros and cons related to its adoption in such a peculiar context, through numerical simulations and comparison with an alternative solution relying on the widely used MD5 hash algorithm.
