Advanced Encryption Standard Process

Advanced Encryption Standard Process

The Advanced Encryption Standard (AES), the block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the aging Data Encryption Standard (DES). This process won plaudits from the open cryptographic community, and helped to increase confidence in the security of the winning algorithm from those who were suspicious of backdoors in the predecessor, DES.

A new standard was needed primarily because DES has a relatively small 56-bit key which was becoming vulnerable to brute force attacks. In addition, the DES was designed primarily for hardware and is relatively slow when implemented in software. While Triple-DES avoids the problem of a small key size, it is very slow even in hardware; is unsuitable for limited-resource platforms, and may be affected by potential security issues connected with the (today comparatively small) block size of 64 bits.

Famous quotes containing the words advanced, standard and/or process:

    I saw my lady weep,
    And Sorrow proud to be advanced so
    In those fair eyes where all perfections keep.
    Her face was full of woe;

    But such a woe, believe me, as wins more hearts
    Than Mirth can do with her enticing parts.
    —Unknown. I Saw My Lady Weep (l. 1–6)

    Where shall we look for standard English but to the words of a standard man?
    Henry David Thoreau (1817–1862)

    We tend to be so bombarded with information, and we move so quickly, that there’s a tendency to treat everything on the surface level and process things quickly. This is antithetical to the kind of openness and perception you have to have to be receptive to poetry. ... poetry seems to exist in a parallel universe outside daily life in America.
    Rita Dove (b. 1952)
