SECURE ULTRALIGHTWEIGHT CRYTOGRAPHY FOR RFID PASSIVE TAG: A SURVEY

Abstract

 RFID system is one of the fastest growing technologies among the automation applications needed in
Organizations, Institution, and Supply Chain Management etc. Along with non-line of sight capability, RFID tag’s
capability of durability, reusability, data encryption, increased storage and faster read rate etc. makes RFID systems
much efficient, faster and robust than other existing systems such as barcodes, magnetic taps etc. The UMAPs are
very important to the widespread deployment of low-cost RFIDs. The UMAPs protocol is vulnerable against
traceability attack and forward traceability attack and many others as attacker uses loopholes arises from the
extremely small memory and very limited calculating power of tags and by using on-tag ultralightweight operations,
which includes the cyclic redundancy check, the exclusive-or, the random number generation, the pseudo random
number generator (PRNG) and lightweight cryptographic hash function operations attacker carries out different
attacks. This weakness present in UMAPs protocol also does not provide the security and privacy of RFID users. We
are taking some UMAP protocol like Yu-Jehn protocol, LMAP, EMAP and others for a survey to study and find the
vulnerabilities in these protocols along with the comparison table. This paper shows review of all UMAP protocols
and vulnerabilities of all the protocols.
