Abstract: A countermeasure dispenser system has a dispenser with a fire pin and a smart expendable housed in the dispenser awaiting to be fired upon a fire command. The smart expendable has features that need power and communication signals from the dispenser. The communication signals and power sent from the dispenser to the smart expendable are sent through an interface that is different than the fire pin in the dispenser. The interface may be a dedicated wired interface or the interface may be a wireless interface. If wireless, the wireless interface may use near field communications, RF signaling, or near field magnetic induction.

Abstract: Apparatus and method for authentication components of a public network are disclosed. A master compares an actual HMAC with an expected HMAC, determines that component fails authentication when the actual HMAC does not match the expected HMAC and causes at least one operation to be inhibited when component fails authentication for a preset number of times while the component is connected to the public network. The actual HMAC is determined by the component. The expected HMAC and actual HMAC are independently determined using the same process and using a key. The same key is stored, in advance, in both the master and the component and not transmitted. The master generates a random number and sends the same to the component. The expected HMAC and actual HMAC are determined using the random number input into a one-way hash function.
