Abstract
Techniques for secure generation of a seed for use in performing one or more cryptographic operations, utilizing a seed generation protocol carried out by a seed generation client () and a seed generation server (). The seed generation server () provides a first string to the seed generation client (). The seed generation client () generates a second string, encrypts the second string utilizing a key (), and sends the encrypted second string to the seed generation server (). The seed generation client () generates the seed as a function of at least the first string and the second string. The seed generation server (s) decrypts the encrypted second string () and independently generates the seed as a function of at least the first string and the second string.
