SOBER Family of Stream Ciphers: A Review

The t-Class of SOBER Stream Ciphers

This paper proposes the t-class of SOBER stream ciphers: t8, t16 and t32. t8, t16 and t32 offer 64-, 128and 256-bit key strength respectively. The t-class ciphers are based on the same principles as the original SOBER family: SOBER [17], SOBER-II [18], S16 and S32 [19], utilising the structure SOBER-II and S16 are based. The t-class ciphers are software stream ciphers designed for software impl...

The Salsa20 Family of Stream Ciphers

Salsa20 is a family of 256-bit stream ciphers designed in 2005 and submitted to eSTREAM, the ECRYPT Stream Cipher Project. Salsa20 has progressed to the third round of eSTREAM without any changes. The 20-round stream cipher Salsa20/20 is consistently faster than AES and is recommended by the designer for typical cryptographic applications. The reduced-round ciphers Salsa20/12 and Salsa20/8 are ...

Pomaranch - Design and Analysis of a Family of Stream Ciphers ∗

Pomaranch is a synchronous, hardware-oriented stream cipher submitted to eSTREAM, the ECRYPT Stream Cipher Project. The cipher is designed as a cascade clock-controlled key-stream generator built on jump registers. This paper presents a discussion over the attacks on Pomaranch discovered so far. Particular focus is made on a new inherent property of jump registers that allows to construct their...

Stream ciphers and the eSTREAM project

Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.
