Abstract
A method manages cryptographic objects (COs). The method includes accessing an entropy-based random number and instructing to store this random number. The method includes generating one or more COs based on a deterministic algorithm that causes to interact with a security module (SM), such as a hardware security module (HSM), to generate a seed according to both a reference key of the SM and the random number accessed. A random number generator is seeded with the generated seed to generate the desired COs.
