Abstract(in English) | This paper discusses the security of the Fast Data Encipherment Algorithm(FEAL)against Linear Cryptanalysis which is one of the most effective attack method.The method derives the secret encryption key in the known-plaintext scenario.It has been confirmed that the entire subkeys used in FEAL-8 can be derived with 2^25> pairs of plaintext and ciphertext within about I hour using a WS(SPARCstation 10 Model 30).This paper also evaluates the security of FEAL-N in comparison with that of the Data Encryption Standard(DES).It is an interesting phenomenon that FEAL-16 is as secure as DES with regard to Linear Cryptanalysis,while FEAL-32 is as secure as DES from the standpoint of Differential Cryptanalysis. |
