Neeva: A Lightweight Hash Function

RFID technology is one of the major applications of lightweight cryptography where security and cost both are equally essential or we may say that cost friendly cryptographic tools have given more weightage. In this paper, we propose a lightweight hash, Neeva-hash satisfying the very basic idea of lightweight cryptography. Neeva-hash is based on sponge mode of iteration with software friendly permutation which provides great efficiency and required security in RFID technology. The proposed hash can be used for many application based purposes.
