A NEW APPROACH FOR REDUCING CACHE TIMING ATTACK IN ADVANCED ENCRYPTION STANDARD USING DCF ALGORITHM

Abstract


Being accepted by many security related applications as the most secured cipher, The AES- Rijndael algorithm has a long successful existence in the field of global security. Despite of this, the AES is recently found to be broken theoretically. However, a few years back, Daniel Bernstein devised a cachetimingattack that was capable enough to break Rijndael’s seal that encapsulates the encryption key. Our paper proposes a new solution called Dynamic Cache Flushing (DCF) algorithm, which provides better security by encrypting key at a constant time over cache timing attack.
