Avoiding Data Replication in Cloud Using SHA-2

2018 Internat2018 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC)ional conference on computation of power, energy, Information and Communication (ICCPEIC), 2018
Duplication occurs in cloud when two or more users try to upload same data who are working under a same organization. Deduplication is a process of avoiding the redundant data from the cloud. In previous systems they have used MD5 algorithm, which avoids performs on both file and content level de-duplication check.

A flexible hardware implementation of SHA-1 and SHA-2 Hash Functions

2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011
This paper summarizes the design of a reprogrammable Application Specific Integrated Circuit capable of performing all members of the Secure Hash Algorithm (SHA) group of Hash Functions. The need for high-speed cryptography is introduced, as well as the SHA-1 and SHA-2 Hash Functions and their operation.

Novel Hardware Architecture for Implementing the Inner Loop of the SHA-2 Algorithms

2011 14th Euromicro Conference on Digital System Design, 2011
Cryptographic algorithms are used to enable security services that are the core of modern communication systems. In particular, Hash functions algorithms are widely used to provide services of data integrity and authentication. These algorithms are based on performing a number of complex operations on the input data, thus it is important to count with ...

Deterministic Constructions of 21-Step Collisions for the SHA-2 Hash Family

2008
Recently, at FSE '08, Nikolic and Biryukov introduced a new technique for analyzing SHA-2 round function. Building on their work, but using other differential paths, we construct two different deterministic attacks against 21-step SHA-2 hash family. Since the attacks are deterministic, they are actually combinatorial constructions of collisions.
