| Abstract(in English) | In this paper we provide the first side-channel analysis of the K2 stream cipher. We apply timing attacks, power analysis, and differential fault analysis to K2. We show that naively implemented K2 is vulnerable to cache-timing attacks, and describe how to implement efficient countermeasures to protect K2 against side-channel attacks in hardware and software. Proposed side-channel attacks would be not practical on common situations, and threats by the side-channel attacks can be avoided to implement our countermeasures. |
