| Abstract(in English) | We investigate the security of Message Authentication Code (MAC), especially the Data Encryption Standard (DES) based scheme DES-MAC, against the linear cryptanalysis, which is a known plaintext attack. To this end, we modify the researching algorithm for linear expression to discover the best linear expression which depends only on the left half 32-bits of the ciphertext. Note that the previous best linear expression of DES essentially includes the right half 32-bits of the ciphertext. We further report experimental results on the cryptanalysis by using our new linear expression for DES-MAC. |
