Abstract: A method distributes personalized circuits to one or more parties. The method distributes a generic circuit to each party, encrypts a unique personalization value using a secret encryption key, and transmits each encrypted personalization value to the corresponding party. Each party then stores the encrypted personalization value in their circuit. The stored encrypted personalization value allows a piece of software to be properly executed by the circuit. A semiconductor integrated circuit is arranged to execute a piece of software that inputs a personalization value as an input parameter. The circuit comprises a personalization memory arranged to store an encrypted personalization value; a key memory for storing a decryption key; a control unit comprising a cryptographic circuit arranged to decrypt the encrypted personalization value using the decryption key; and a processor arranged to receive the decrypted personalization value and execute the software using the decrypted personalization value.
