Point-to-point anonymous communication method based on random stateless address allocation strategy in IPv6 network

Abstract

The invention discloses a point-to-point anonymous communication method based on a random stateless address allocation strategy in an IPv6 network, belonging to the technical field of the Internet. The present invention is based on the onion routing anonymous communication mechanism, by improving the IPv6 address generation algorithm, using the huge IPv6 address space, periodically changing the node IPv6 address, avoiding the privacy leakage caused by the IPv6 address identification; using the onion routing mechanism to ensure the IPv6 address Cross-network segment hiding and data encryption. The method can obviously improve the anonymity of the anonymous communication system, and the communication efficiency and compatibility of the system are not weakened. The invention has the advantages of: (1) significantly improving the anonymity of the anonymous communication system; (2) the communication efficiency and compatibility of the system are not weakened; (3) strong universality. The present invention can provide multiple effective security communication technologies for the application of the Internet in the future, has good expansibility, and can adapt to the requirements brought about by the development of the application of the Internet in the future.

Description

technical field [0001] A point-to-point anonymous communication method based on a random stateless address allocation strategy in an IPv6 network belongs to the field of Internet technology, and in particular relates to the technology in the field of next-generation Internet communication. Background technique [0002] The main purpose of anonymous communication is to hide the relationship between the two parties during the communication process, so as to protect the privacy of both parties. The basic idea of ​​anonymous communication is to use the hop-by-hop forwarding of multiple nodes to hide the relationship between the real communication parties, and use the keys of each node to encrypt the forwarded content in multiple layers, so that each intermediate node can only know its own predecessor Nodes and successor nodes, but cannot obtain the information of the real communication parties. The initial anonymous communication adopts the idea of ​​public key encryption, but ...

Problems solved by technology

However, since the scheme itself is not designed to cooperate with anonymous communication, it is not difficult to set parameters, etc.

Moreover, simple IP address translation cannot achieve communication anonymity, because the attacker can still associate the two parties through the communication content, and the address translation can only be limited to a LAN segment, and the attacker can still relatively simple to track
