Abstract 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. Neevahash
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. 2010 Mathematics Subject Classification. 94A60. Keywords and phrases. Hash function, Lightweight cryptography, Present, Quark,
Sponge construction, Spongent. |
