Zusammenfassung:A device (1) is intended for managing multiple accesses to a secure module (5) of a system on chip (2) of an apparatus (3), and comprises a stream ciphering means (13 1 , 13 2 ) arranged for computing on the fly and in a single pass an integrity check for data to be transferred between secure (5) and non secure (4) modules of the system on chip (2) with a seed and an encryption key, and for encrypting/decrypting on the fly and in this single pass these data with the encryption key, and a control means (11 1 , 11 2 ) for providing the encryption key and seed to the stream ciphering means (13 1 , 13 2 ) and for requesting data transfer and retrieving status to the secure (5) and non secure (4) modules for allowing the transfer of encrypted/decrypted data between the secure (5) and non secure (4) modules.
