SECURE SYSTEM-ON-CHIP

A secure system-on-chip for processing data, the system-on-chip comprising at least a central processing unit (CPU), an input and an output channel, an encryption/decryption engine and a memory, wherein, said input channel comprises an input encryption module to encrypt all incoming data, said output channel comprising an output decryption module to decrypt all outgoing data, said CPU receiving the encrypted data from the input encryption module and storing them in the memory, and while processing the stored data, said CPU reading the stored data from the memory, requesting decryption of same in the encryption/decryption engine, processing the data and requesting encryption of the result by the encryption/decryption engine and storing the encrypted result, outputting the result to the output decryption module for decryption purpose and exiting the decrypted result via the output channel.
