Abstract :
The Common Scrambling Algorithm (CSA) is used to encrypt streams of video data in the Digital Video Broadcasting (DVB) system. To date, CSA is secure against classical attacks, but vulnerable to side channel attacks. This paper presents a differential power analysis , one of side channel attacks, on DVB CSA. By decrypting the block cipher part, the common key of the whole algorithm can be derived. It provides a general method for other ciphers against side channel attacks.
