SOBER-128


SOBER-128

SOBER-128 is a synchronous stream cipher designed by Hawkes and Rose (2003) and is a member of the SOBER family of ciphers. SOBER-128 was also designed to provide MAC (Message authentication code) functionality.

Watanabe and Furuya (2004) showed a weakness in the MAC generation of SOBER-128 which means an attack could forge a message with probability 2-6. MAC functionality was deleted by Qualcomm from SOBER-128 reference code.

SOBER-128 takes a key up to 128-bits in length.
