| Abstract | The Secure Hash Algorithm is the most popular hash function currently used in many security protocols such as SSL and IPSec. Like other cryptographic algorithms, the hardware implementation of hash functions is of great importance for high speed applications. Because of the iterative structure of hash functions, a single error in their hardware implementation could result in a large number of errors in the final hash value. In this paper, we propose a novel time-redundancy-based fault diagnostic scheme for the implementation of SHA-1 and SHA-512 round computations. This scheme can detect permanent as well as transient faults as opposed to the traditional time redundancy technique which is only capable of detecting transient errors. The proposed design does not impose significant timing overhead to the original implementation of SHA-1 and SHA-512 round computation. We have implemented the proposed design for SHA-1 and SHA-512 on Xilinx xc2p7 FPGA. It is shown that for the proposed fault detection SHA-1 and SHA-512 round computations, there are, respectively, 3% and 10% reduction in the throughput with 58% and 30% area overhead as compared to the original schemes. The fault simulation of the implementation shows that almost 100% fault coverage can be achieved using the proposed scheme for transient and permanent faults. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
