“…Some other works [25], [26], [27] provide further comparisons of FPGA-based implementations of hash functions. Also, some optimizations based on pipelining, loop unrolling, operation rescheduling and hardware reutilization are proposed in [28], [29]. Previous research has extensively addressed the implementation of the SHA-2 family of hash functions.…”

Abstract-Satellites are extensively used by public and private sectors to support a variety of services. Considering the cost and the strategic importance of these spacecrafts, it is fundamental to utilize strong cryptographic primitives to assure their security. However, it is of utmost importance to consider fault tolerance in their designs due to the harsh environment found in space, while keeping low area and power consumption. Therefore, this paper proposes novel fault tolerant schemes for the SHA-2 family of hash functions and analyzes their resistance to SEUs. Results obtained through FPGA implementation show that our best fault tolerant scheme for SHA-512 uses up to 32% less area and consumes up to 43% less power than the commonly used TMR technique. Moreover, its memory and registers are 435 and 175 times more resistant to SEUs than TMR. These results are crucial for supporting low area and low power fault tolerant cryptographic primitives in satellites.

“…Efforts for optimisation have been paid for both SHA-1 and SHA-256 (Yiakoumis et al, 2006;Michail et al, 2005) which are the most widely deployed hash functions. In this work, the authors propose an optimisation for RIPEMD-160.…”

One-way hash functions are the main cryptographic primitives which are used in the network protocols for user authentication and message integration. In the literature, implementations have been proposed either in hardware or software. The rich number of implementations is expected considering the number of constraints of a target application. When the target is to service more and more users-clients and thus the increase of their throughput, a hardware implementation is dictated. In this paper, RIPEMD-160 hash function is considered and a technique to increase its throughput. This technique involves the application of algorithmic transformations in space and time. The proposed technique leads to an increased throughput by 35% when compared to conventional implementations.

In this era of technology with an increasing usage of Internet, data security has become a major issue.Various cryptographic hash function such as MD4, MDS, SHA-1, SHA-2 has been defined to provide data security. In this paper we proposed a new algorithm, TL-SMD (Two Layered Secure Message Digest) for building a secure hash function, which can provide two level processing security. For the construction of this algorithm, various techniques have been used that includes block cipher technique, modified combination of Merkle-Damgard construction and fast wide pipe construction. For computing the hash value from the input block, combination of cipher block chaining (CBq mode and electronic code book (ECB) mode with some modification is used.
