SSL handshake protocol based on batch key redistribution
基于批量化密钥重分配的SSL握手协议

SSL handshake protocol could provide data confidentiality and integrity by public key cryptosystem between two communicating entities. Shortcoming of the protocol was that processing speed was too slow. It introduced that batch RSA could be used to speedup SSL handshake protocol, but server overload was either due to a lot of legitimate client requests or a denial-of-service (DoS) attack. For this reason, this paper proposed a promising protocol based on batch key redistribution. The protocol divided the private key into two key sequence and sent one of two key sequences to client, which shifted some computational burden from the server to the client, so the technique could speed up RSA decryption and reduce overload of sever. Analysis and experimental results show that the protocol can ensure the safety of information transmission and improve the processing speed.
