Multiparty Quantum Cryptography with Block Cipher RC6 (B- MQKD)


The proposed B-MQKD method uses a quantum key distribution to generate a key and provide an authentication amongst many parties. It uses concepts of block cipher by using RC6 algorithm for encryption. The mix concept in B-MQKD (quantum and block cipher) gives the algorithm more authentication, randomness, and security which make it difficult to find the original message by attackers. In this paper using BB84 among three parties make it possiple to give the key to many users in a secret way.
