On designing secure small-state stream ciphers against time-memory-data tradeoff attacks
Stream cipher Ultra-lightweight Small-state
2019/6/10
A new generation of stream ciphers, small-state stream ciphers (SSCs), was born in 2015 with the introduction of the Sprout cipher. The new generation is based on using key bits not only in the initia...

Time-memory-data (TMD) tradeoff attacks limit the security level of many classical stream ciphers (like E0E0, A5/1, Trivium, Grain) to 12n12n, where nn denotes the inner state length of the underlying...

Time-Memory-Data tradeoff attacks (TMD-attacks) like those of Babbage, Biryukov and Shamir, and Dunkelman and Keller reduce the security level of keystream generator based-stream ciphers to L/2L/2, wh...

Time-Memory Tradeoff (TMTO) attacks on stream ciphers
are a serious security threat and the resistance to this class of attacks is
an important criterion in the design of a modern stream cipher. TMT...
