http://tools.ietf.org/html/draft-rescorla-tls-extended-random-02

"The United States Department of Defense has requested a TLS mode
which allows the use of longer public randomness values for use with
high security level cipher suites like those specified in Suite B
[I-D.rescorla-tls-suiteb].  The rationale for this as stated by DoD
is that the public randomness for each side should be at least twice
as long as the security level for cryptographic parity, which makes
the 224 bits of randomness provided by the current TLS random values
insufficient."

Cheers,
Michael
