Abstract
An electronic device includes processing circuitry and one or more memories, including a non-volatile memory. Ephemeral cryptographic key generation circuitry, in operation, applies a function to code stored in the non-volatile memory, generating an ephemeral cryptographic key. Cryptographic circuitry coupled between the processing circuitry and the one or more memories, in operation, performs one or more cryptographic operations on data using the generated ephemeral cryptographic key. The device may include a register, which, in operation, temporarily stores the generated ephemeral cryptographic key.
