Point-to-point anonymous communication method based on random stateless address distributing policies in IPv6 network

Abstract

The invention relates to a point-to-point anonymous communication method based on random stateless address distributing policies in an IPv6 network and belongs to the Internet technical field. Based on an onion routing anonymous communication mechanism, the IPv6 address of a node is changed periodically through an improved IPv6 address algorithm and by means of a huge IPv6 address space, and therefore, privacy leakage caused by an IPv6 address identifier can be avoided; and cross-network segment hiding and data encryption of the IPv6 address can be ensured through the onion routing mechanism. With the method adopted, the anonymous performance of an anonymous communication system can be obviously improved; the communication efficiency and the compatibility of the system are not weakened; and various kinds of effective safe communication technologies can be provided for future Internet applications. The method has high universality and excellent expansibility, and can meet the requirements of the development of the future Internet applications.

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
