Abstract :
The PingPong family of keystream generator is based on the LM-type summation generator. A mutual-clock-control mechanism is added to the LM-type summation generator to provide a security enhancement. PingPong-128, a specific cipher from the PingPong family, is proposed. It takes a 128-bit key and a 128-bit initialisation vector, has 257 bits of internal state, and achieves a security level of 128 bits. In this paper, we present the security analysis of PingPong-128, including the resistance to known attacks against the summation generator and other clock-controlled generators.
