Abstract

A universal hash function M-hash with low complexity that suitable for low cost passive RFID tags is proposed.Taking parallel LFSR as the basic component Mhash provides the security of hash function using one-wayness brought by the information loss in the process of compression.As shown through strict theoretical proof,Mhash is a regular hash function with balance equals to 1.M-hash is better than Toeplitz hash in aspects of security and hardware complexity.
