The SST includes a peripheral device, such as a cash dispenser, and a security controller device including a memory device and a coupling to the peripheral device. The security controller device is operable to perform data processing activities including receiving peripheral device identifying data from the peripheral device and transmitting a public key (SC) of the security controller device to the peripheral device. The security controller may then decrypt a received peripheral device encryption key (Ki) according to SC, generate a first security controller encryption key (Ke), and generate a first message authentication code key and encrypt the first message authentication code key according to Keto obtain (Km)Ke. (Km)Kemay then be stored in the memory device and transmitted to the peripheral device.
