Breaching Security of Full Round Tiny Encryption Algorithm

Sobti, Rajeev; Kaushal, Puneet Kumar - In: International Journal of Information Security and … 12 (2018) 1, pp. 89-98

Tiny encryption algorithm is a 64-bit block cipher designed by Wheeler and Needham in 1994 and attracted much of its attention due to its capability of reducing the hardware cost. In this paper, we introduced coincidence count attack at bit level, a kind of known-plaintext attack and evaluated...

Cryptanalysis of a new ultralightweight RFID authentication protocol—SASI

Phan, Raphael C.-W. - 2009

Since RFID tags are ubiquitous and at times even oblivious to thehuman user, all modern RFID protocols are designed to resist tracking so that thelocation privacy of the human RFID user is not violated. Another design criterionfor RFIDs is the low computational effort required for tags, in view...

Security analysis of a chaos-based image encryption algorithm

Lian, Shiguo; Sun, Jinsheng; Wang, Zhiquan - In: Physica A: Statistical Mechanics and its Applications 351 (2005) 2, pp. 645-661

The security of Fridrich's algorithm against brute-force attack, statistical attack, known-plaintext attack and select-plaintext attack is analyzed by investigating the properties of the involved chaotic maps and diffusion functions. Based on the given analyses, some means are proposed to...
