Abstract

The onion routing protocol enables low-latency anonymous communication over the public network. Currently, many onion routing protocols have been proposed to enable anonymous connections between users, such as Tor. Even though existing onion routing protocols appear to have a secure structure, there are still some disadvantages in terms of efficiency and security. This paper proposes a new onion routing protocol based on certificateless group signature, which uses the new designed certificateless group signature scheme to achieve anonymous authentication of messages. In the protocol, this paper modifies the data encapsulation format of the transmission, and uses only the key shared with the receiver to encrypt the data payload in a single layer. The proposed protocol not only reduces the encryption and decryption operations of the data packets in the transmission process, but also improves the forwarding efficiency of the message, and further realizes the anonymous authentication and integrity of the message forwarding.
