Abstract
Systems and techniques are provided for generating cryptographic keys. For instance, a process may include generating a plurality of master keys based on a plurality of generated random numbers, a second number, and a nonce number; storing a master key, of the plurality of master keys, along with a generated random number of the plurality of generated random numbers, the second number, and the nonce number used to generate the master key in a one-time programmable memory; generating public key-private key pairs for the plurality of master keys; transmitting public keys of the plurality of public key-private key pairs for audit; destroying an audited master key, along with the generated random number, second number, and the nonce number used to generate the audited master key, based on the audit; and storing a non-audited public key-private key pair corresponding to the master key that were not destroyed based on the audit.
