Abstract
An embodiment integrated circuit comprises a first memory zone having a first level of access rights that is configured to store at least one first software application containing encrypted instructions, means for verifying the integrity of the first software application, an encryption/decryption means, for example a first logic circuit, that is configured to decrypt the encrypted instructions which are considered to exhibit integrity, a processing unit that is configured to execute the decrypted instructions, the first logic circuit being further configured to encrypt the data generated by the execution operation and a second means, for example a second logic circuit, that is configured to store the encrypted data in a second memory zone having a second level of access rights that is identical to the first level of access rights.
