A Novel Architecture for Lightweight Block Cipher, Piccolo
Security and privacy are going to be the key factors for the deployment of new applications, since people will only accept these deployments if these are based on secure, trustworthy and privacy-preserving infra-structures. Cryptography plays a major role in the security of data transmission and the development of computing technology imposes stronger requirements on the cryptography schemes. L...
متن کاملDifferential 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...
متن کاملNew Observations on Piccolo Block Cipher
To reduce the cost in hardware, key schedules of lightweight block ciphers are usually simple and some even are direct linear transformations on master keys. Designers always add some asymmetry rounddependent constants to prevent the well-known slide attack. For linear key schedules, the choice of round constants becomes important but lacks principles. In this paper, we aim at evaluating the ro...
متن کاملLBlock: 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...
متن کاملFeW: A Lightweight Block Cipher
In this paper, we propose a new lightweight block cipher called FeW 1 which encrypts 64-bit plaintext using key size 80/128 bits and produces 64-bit ciphertext. FeW is a software oriented design with the aim of achieving high efficiency in software based environments. We use a mix of Feistel and generalised Feistel structures (referred as Feistel-M structure hereinafter) to enhance the security...
