Abstract
A first network device nonce is computed. The first network device nonce is based on a first network device secret. A Change Token Table message (CTTM) is sent to a second network device. The CTTM comprises the first network device nonce. A Change Token Table Ack Message (CTTAM) with a second network device nonce is received from the second network device. A new token for a tokenization table is computed based on the first network device secret, the second network device nonce, a prime number, and a key derivation function. The new token for the tokenization table is also computed by the second network device based on a second network device secret, the first network device nonce, the prime number, and the key derivation function.
