Abstract
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.
Highlights
The design of new proposed B-MQKD (Multiparty Quantum Key Distribution with block cipher) as encryption system used the principle of protocol BB84 with multi parties to generate a secret shared key, provide an authentication among these parties that communicate together and randomness in generating a key
When Bob receives this sequence, called “raw key”, he chooses the basis of each qubit, his measure is either like Alice basis or different from Alice basis and sometimes he does not measure anything
The receiver agrees with the sender on ID, which sends it to server when he/she needs to get the correct polarize from server to convert it to a secret key with 128-bit
Summary
The design of new proposed B-MQKD (Multiparty Quantum Key Distribution with block cipher) as encryption system used the principle of protocol BB84 with multi parties to generate a secret shared key, provide an authentication among these parties that communicate together and randomness in generating a key.
