Abstract
The present disclosure provides for using a random trigger probability for determining whether to rotate cryptographic keys. The random trigger probability may be applied for each cryptographic operation that might yield a nonce collision. For example, the random trigger probability may be pre-computed, and each time a request to perform a cryptographic operation is received a random event with the trigger probability may be executed. Based on the random trigger probability, it is determined whether to rotate keys. The random trigger may be a function of a threshold for acceptable probability of failure, and parameters for a type of cryptographic operation and key.
