Xiaoyong Li · Information Security and Communications Privacy · 2007
Side-channel attacks bring forth serious threat to cryptography security; it reduces the complexity of cryptanalysis by utilizing some characteristics in hardware/software implementation of the cipher. Being the main encryption standard for the present time and the future, the security of AES is of a special importance However, recent researches have revealed that, AES cipher program on mainstream computing platforms may suffer from one kind of attack resulted from the leaked running information through Cache. According to related research, this paper proposes the basic processes of such attack, describes its current status and progresses, analyzes its feasibility in real world, and explains the countermeasures and suggestions.
