Abstract (en)

[origin: WO2021071719A1] Disclosed are various embodiments for executing entity-specific cryptographic code in a cryptographic coprocessor. In one embodiment, encrypted code implementing a cryptographic algorithm is received from a service via a network. The cryptographic coprocessor decrypts the encrypted code. The cryptographic coprocessor executes the decrypted code to generate a cryptogram including information encrypted using the cryptographic algorithm. The cryptogram is sent to the service via the network.
