Abstract
The present application describes a method, system, and non-transitory computer-readable medium for generating new keys during a secure communication session. A key derivation function is operatively connected to both a counter and a memory. The key derivation function generates new key material from a first input and a second input in response to a signal provided by the counter. The key derivation function generates the new key material and outputs it to the memory.
