Network resource query method and system

Abstract

The invention discloses a network resources inquiry method. A client side and a server side are equipped with the same security policy which is an algorithm used in the whole identity authentication process. The method comprises the following steps: the client side sends a resource inquiry request to the server side, and the server side indicates the client side to authenticate identity after receiving the resources inquiry request; after the identity authentication is passed, the server side inquires resources to obtain a resources inquiry result, and sends back the resources inquiry result to the client side. The invention also further provides a network resources inquiry system. The network resource inquiry method and the system ensure that the valid client side can successfully pass the identity authentication and obtain the resources inquiry result, avoid hackers or rivals from illegally stealing information in the resource information database, and greatly enhances the information security in the resource information database.

Description

technical field [0001] The invention relates to information security technology, in particular to a network resource query method and system. Background technique [0002] At present, with the explosive growth of information capacity and the rapid development of Internet technology, it is more and more obvious that people rely on the Internet to obtain various information they need. After people find the information resources they need from the Internet, although some of them can be used repeatedly online, most of the information still needs to be downloaded to the local computer for use. Because the download software can provide a higher download speed, the download software has developed rapidly as a special type of application software. [0003] Most of the current downloading software adopts the multi-resource downloading technology. The multi-resource downloading technology refers to the Uniform Resource Locator (Uniform Resource Locator, URL) link of the information r...

[0011]However, the security of the above method is completely based on the key, and the key itself has no automatic update mechanism, and generally the same key will be used for a long time Information exchange will undoubtedly increase the possibility of the key itself being leaked; at the same time, information thieves or hackers can also use calculation or cryptography rules to infer the key used by intercepting a sufficient number of encrypted ciphertexts.

For example, the 64-bit shared key that was once commonly used can no longer be used because it was cracked by hackers

[0012] It can be seen from the above that since the existing symmetric encryption method is completely open, its security depends entirely on the key agreed by the two parties in the information exchange, and the key cannot be automatic update

Therefore, if the key is lost, leaked or cracked, the information thief will be able to pretend to be a client and use the key to steal information resources in the resource information database, thereby making the information in the resource information database safe and operational. Business interests are seriously threatened
