Abstract
A requirement for a pseudo-random number is identified. A usage context corresponding to the requirement is determined from among a plurality of usage contexts. A cryptographic transformation function is applied to a first pseudo-random number obtained from a pseudo-random number generator. The transformation function meets a security criterion which is based on the usage context. A result of the function is used to fulfill the requirement.
