  • Authenticating devices over a public communication network
    Patent number: 11303455
    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.
