Method for implementing wireless network safety communication

Abstract

The invention belongs to the safety technical field of computer networks and discloses an achieving method of the safe communication of a wireless network. The achievement on the method bases on the identification of identity and the processed innovation of IKEV2 protocol. The invention adds an encrypted gateway between a wireless bridge and a wire local area network. The communicating physical body in the method has two encrypted keys (a common key and a private key). Each physical body has an incommon private key. The senders of the message adopt the private key to sign and the receivers carry out inspection with the identity of the senders (namely the common key). The communicating physical body does not need the signature of the identifying center (CA) to the certificates, and thus saves the computing capacity of the communicating physical bodies. The method included in the invention ensures the transmitting safety of the information for the wireless network communication solves the problems such as data encryption, identity identification, maintenance on the integrity of the data and management on the encryption, with the safe transmission of the business data.

Description

technical field [0001] The invention relates to the technical field of computer network security, in particular to a method for realizing wireless network security communication. Background technique [0002] With the rapid development of information technology, people's demand for network communication continues to increase. People want to be able to communicate with anyone, including data, voice and images, no matter when, where, and with anyone, and wireless communication and its networking technology have emerged as the times require. Compared with the wired network through cables, optical cables or twisted pairs, wireless electromagnetic waves, lasers, infrared rays, etc. are used to partially or even completely replace physical cables and become the main communication transmission medium between network devices, thus forming a wireless communication network. However, wireless communication is easily troubled by security risks and security issues. Since the business da...

However, the WEP standard also has inherent defects in protecting network security. For example, all users in a service area share the same key, and if a user loses or leaks the key, the entire network will be insecure.
