Network resource access control method in reliable access

Abstract

The invention relates to an access control method of network resources in trusted access, which belongs to the field of network communication. The method comprises the following steps: a trusted access server carries out system initialization, key document distribution and resource access control; wherein the system initialization of the trusted access server comprises the steps of using an SEA algorithm to establish elliptic curves randomly and selecting a point G as a first base point on the elliptic curves randomly; the key document distribution comprises the steps of key distribution of resource owners st and key distribution of terminal mt'; the resource access control comprises the steps of using a private key kt'->t to carry out signing to request information when a terminal mt' accesses a resource owner st and using a public key Gx#-t and a second base point Gm#-t'->t to carry out checking to the terminal mt' when the resource owner st receives the request information. Only passing the checking, the terminal mt' can be proved to own the private key kt'->t, thereby being the terminal authorized by the trusted access server. The invention can effectively reduce the space occupied by the resource owner for storing the terminal information and reduce the expenditure of the checking calculation simultaneously.

Description

technical field [0001] The invention relates to a network resource access control method, in particular to a network resource access control method in trusted access, belonging to the field of network communication. Background technique [0002] In recent years, with the popularization of various access technologies, the number of Internet users has also shown an explosive growth trend. According to the statistics of the Internet Society of China, by the end of 2006, the number of Internet users in my country had reached 130 million, with an annual growth rate of 30%. The increase in the number of network users has also greatly increased the possibility of network security attacks. Network hackers can easily spread viruses through computer networks, steal credit card accounts, and use network security loopholes to obtain commercial benefits, which has brought a lot of Cybercriminal activity. According to the data released by my country's public security organs, in 2005, my ...
