Abstract: The method involves selecting a secret key from keys stored with key identifiers in registers. Data is divided into a stream of data words of determined size. A pseudo-random number is generated based on the secret key and an initialization vector. The data word and number are combined to generate an encrypted data word and the encrypted data word is stored with the vector and the identifier of the key in an external memory (23). Independent claims are also included for the following: (A) a device for implementing a data encrypting method (B) an electronic apparatus having processors with encrypting/decrypting unit.

Abstract: The method involves booting a boot-strap processor (BSP) (2) to protect part of a RAM (4) to form a secure domain. An operating system (OS) of BSP is booted to store data of OS in the protected part. An application processor (AP) (2) is booted, and the domain is extended to AP, in case of successful authentications of AP and BSP, by accessing the protected part. The OS of the AP is booted to store data of OS in the protected part. An independent claim is also included for an electronic apparatus having processors connected to a RAM through a communication bus.
