SOBER

Family of stream ciphers

In cryptography, SOBER is a family of stream ciphers initially designed by Greg Rose of QUALCOMM Australia starting in 1997. The name is a contrived acronym for Seventeen Octet Byte Enabled Register. Initially the cipher was intended as a replacement for broken ciphers in cellular telephony. The ciphers evolved, and other developers (primarily Phillip Hawkes) joined the project. SOBER was the first cipher, with a 17-byte linear-feedback shift register (LFSR), a form of decimation called stuttering, and a nonlinear output filter function. https://en.wikipedia.org/wiki/SOBER
