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.

Systems and techniques are provided for establishing a connection. For instance, a process may include receiving, by a first root of trust (C-ROT) of a first chiplet of a plurality of chiplets from a second C-RoT of a second chiplet, a second certificate along with security state information and debug information for the second chiplet; authenticating a security state and a debug state of the second chiplet based on the security state information and the debug information; authenticating the second certificate; and establishing a security boundary with the second chiplet.
