| Abstract | Most widely used security protocols, Internet Protocol Security (IPSec), Secure Socket Layer (SSL), and Transport Layer Security (TLS), provide several cryptographic services which in turn require multiple dedicated cryptographic algorithms. A single cryptographic primitive for all secret key functions utilizing different mode of operations can overcome this constraint. This paper investigates the possibility of using AES and Keccak as the underlying primitives for high-speed and resource constrained applications. Even though a plain AES implementation is typically much smaller and has a better throughput to area ratio than a plain Keccak, adding additional cryptographic services changes the results dramatically. Our multi-purpose Keccak outperforms our multi-purpose AES by a factor of 4 for throughput over area on average. This underlines the flexibility of the Keccak Sponge and Duplex functions. Our multi-purpose Keccak achieves a throughput of 23.2 Gbps in AE-mode (Keyak) on a Xilinx Virtex-7 and 28.7 Gbps on a Altera Stratix-IV. In order to study this further we also implemented two versions of a dedicated Keyak and dedicated AES-GCM. Our dedicated Keyak implementation outperforms our dedicated AES-GCM on average by a factor 6 in terms of throughput over area reaching a throughput of 28.9 Gbps and 4.1 Gbps respectively on a Xilinx Virtex-7. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
