Symmetric-key Algorithm - Key Generation

Key Generation

When used with asymmetric ciphers for key transfer, pseudorandom key generators are nearly always used to generate the symmetric cipher session keys. However, lack of randomness in those generators or in their initialization vectors is disastrous and has led to cryptanalytic breaks in the past. Therefore, it is essential that an implementation uses a source of high entropy for its initialization.

Famous quotes containing the words key and/or generation:

    Sunshine of late afternoon—
    On the glass tray

    a glass pitcher, the tumbler
    turned down, by which

    a key is lying—And the
    immaculate white bed
    William Carlos Williams (1883–1963)

    There is such a thing as food and such a thing as poison. But the damage done by those who pass off poison as food is far less than that done by those who generation after generation convince people that food is poison.
    Paul Goodman (1911–1972)
