Master subjects should ideally be very practical, to allow students to apply the knowledge they have acquired to the solving of specific problems. This paper proposes the design of a secure communications system using an SPI bus as a Master subject. The system designed uses a stream cipher to encrypt and decrypt data and allows transmission of random length messages. It also uses CRCs to check message integrity.
