| Summary: | Security is the most tedious problem in highly sensitive communications. Quantum security is the key
issue in solving the problem. A key distribution protocol based on the use of hash functions is proposed.
The essential part of the protocol depends on sending a string of random characters from sender to
receiver. Then, a selected hash or a cascade of two hash functions and a long-term shared secret are used
to construct the key. Consequently, the session key is generated on-site by independently applying a hash
function on the random string at the sender and receiver sides. This protocol requires a reliable method of
authentication. Therefore, it is further proposed to use an out-of-band authentication methodology based
on the deterministic six-state quantum authentication protocol that is referred to as 6DP. |
