Shamir's Discrete Logarithm Hash // for possible inclusion into open-pgp ?

2003-11-10 10:40:54

Shamir's Discrete Logarithm Hash was recently implemented by Ralf Senderek
in a new small crypto program, PCP (Pure Crypto Project)

(hash description is here:)
http://senderek.de/SDLH/

it has been around for a while, was proven to be collision resistant,
 but hasn't really been implemented before, possibly because of the length
of time required to sign directly with the rsa key

now, with faster processors,
this may be an appropriate hash for e-mail-length messages,

and, as there are plans for the wider SHA hashes to be introduced,
maybe it would be worthwhile considering a hash will remain secure as
long as the keysize is considered secure

(although it won't work for dh keys ;-(  )


just a thought,

vedaal
