    Abstract: The application relates to a processing device comprising a buffer coupled to a system bus, a ciphering device coupled to the system bus, and a memory coupled to the ciphering device. The processing device is configured to operate in at least one of a deciphering mode and a ciphering mode. In the deciphering mode, the ciphering device is configured to receive a ciphered data unit directly from the buffer over the system bus, decipher the ciphered data unit so as to obtain a deciphered data unit, and transfer the deciphered data unit to the memory. In the ciphering mode, the ciphering device is configured to receive a data unit from the memory, cipher the data unit so as to obtain a ciphered data unit, and transfer the ciphered data unit directly to the buffer over the system bus.
