    IDEA is an *unofficial* replacement for DES. Blowfish is another one. Both
    address DES's vulnerability to brute-force attacks. Triple DES also
    addresses this, by simulating a 162-bit key (3 * 54).

    AES is the *official* - i.e., FIPS - replacement for DES. Any of the AES
    finalists (Rijndael, the winner; Serpent; Twofish, derived from Blowfish;
    RC6; MARS) could be a practical replacement for DES in commercial
    applications.

    · IDEA is a replacement for the DES.

    I thought AES is going to replace DES. This is another statement in the
    CISSP Exam books
