Cryptanalysis of Tav-128 Hash Function
Many RFID protocols use cryptographic hash functions for their security. The resource constrained nature of RFID systems forces the use of light weight cryptographic algorithms. Tav-128 is one such 128-bit light weight hash function proposed by Peris-Lopez et al. for a low-cost RFID tag authentication protocol. Apart from some statistical tests for randomness by the designers themselves, Tav-12...
متن کاملAttacking the Tav-128 Hash function
Many RFID protocols use cryptographic hash functions for their security. The resource constrained nature of RFID systems forces the use of light weight cryptographic algorithms. Tav-128 is one such light weight hash function proposed by Peris-Lopez et al. for an RFID authentication protocol. In this article we show that Tav-128 is not collision resistant. We show a practical collision attack ag...
متن کاملCollision Attack on the Waterfall Hash Function
We give a method that appears to be able to find colliding messages for the Waterfall hash function with approximately O(2) work for all hash sizes. If correct, this would show that the Waterfall hash function does not meet the required collision resistance.
متن کاملCollision Resistance of Double-Block-Length Hash Function against Free-Start Attack
In this article, we discuss the security of double-blocklength (DBL) hash functions against the free-start collision attack. We focus on the DBL hash functions composed of compression functions of the form F(x) = ( f (x), f (p(x))), where f is a smaller compression function and p is a permutation. We first show, in the random oracle model, that a significantly good upper bound can be obtained o...
متن کاملCollision Attacks on the Reduced Dual-Stream Hash Function RIPEMD-128
In this paper, we analyze the security of RIPEMD-128 against collision attacks. The ISO/IEC standard RIPEMD-128 was proposed 15 years ago and may be used as a drop-in replacement for 128-bit hash functions like MD5. Only few results have been published for RIPEMD-128, the best being a preimage attack for the first 33 steps of the hash function with complexity 2. In this work, we provide a new a...
