    摘要: Systems and methods are provided for enchancing pseudo random number generation to thwart various security attacks to a system that relies on digital signature security measures. For example, a random number may be bound to a message that is to be signed using a digital signature. Alternatively, a random number may be bound to a secret seed value, which may be updated subsequent to each signing. Alternatively still, a random number may be bound to both the message to be signed using a digital signature and a secret seed value.
