Abstract:
A symmetric key to be used to secure a communication link between a first device and a second device is generated as follows: a first symmetric key is generated; a second symmetric key is generated; packets communicated between the first device and the second device over communication link are hashed to create a hash result; the first symmetric key, the second symmetric key and the hash result are hashed to generate a third symmetric key to be used to secure the communication link.
