Differential Fault Analysis on Lightweight Block Cipher LBlock

Improved differential fault analysis on lightweight block cipher LBlock for wireless sensor networks

LBlock is a 64-bit lightweight block cipher which can be implemented in both constrained hardware environments, such as wireless sensor network, and software platforms. In this paper, we study the security of LBlock against a differential fault analysis. Based on a random nibble fault model, we propose two versions of the attack on LBlock. In the first attack, we inject random nibble faults to ...

LBlock: A Lightweight Block Cipher

In this paper, we propose a new lightweight block cipher called LBlock. Similar to many other lightweight block ciphers, the block size of LBlock is 64-bit and the key size is 80-bit. Our security evaluation shows that LBlock can achieve enough security margin against known attacks, such as differential cryptanalysis, linear cryptanalysis, impossible differential cryptanalysis and related-key a...

Differential Fault Analysis on Block Cipher Piccolo

Piccolo is a 64-bit block cipher suitable for the constrained environments such as wireless sensor network environments. In this paper, we propose differential fault analysis on Piccolo. Based on a random byte fault model, our attack can recover the secret key of Piccolo-80 by using an exhaustive search of 2 and six random byte fault injections on average. It can be simulated on a general PC wi...

Survey on Lightweight Block Cipher

183  Abstract— With the rapid advances in wireless networks low-end devices, such as RFID tags, wireless sensor nodes are deployed in increasing numbers each and every day. Such devices are used in many applications and environments, leading to an ever increasing need to provide security. When choosing security algorithms for resource-limited devices the implementation cost should be taken int...
