Enhanced-Bivium Algorithm for RFID System

الملخص EN

RFID (radio frequency identification) is an emerging technology for automatic identification of physical objects using radio frequency.

The security and privacy of the system is increasingly concerned and some light-weight encryption schemes such as Trivium and Bivium have been proposed.

In this paper, the internal structure of Bivium is exploited and generalized to an algorithm called Bivium-Model.

It is shown that the original Bivium has its inherent imperfections due to the improper parameter selection.

A set of better parameters are given out to fix the security vulnerability of original Bivium.

Emulation results also show that the Enhanced-Bivium algorithm achieves lower power consumption and lower die size.
