Problems solved by technology

[0014] This method has a big weakness, that is, the upgrade package generator must remember the current value of each user’s upgrade terminal. When the number of user upgrade terminals is large, the workload of the upgrade package generator will increase sharply.

Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] Aiming at the problems existing in the prior art, the embodiment of the present invention adopts adding a time stamp combination to the upgrade package, and the user terminal can determine whether an upgrade is required by comparing the time stamps, avoiding that the upgrade package generating terminal in the prior art must remember each user The authorized value of the current number of available times on the upgrade side, in addition, use the key Key' corresponding to the Key saved by the user side to determine the user side, the use of the key pair ensures the uniqueness of the user side, so as to solve the replayability of information security equipment at the same time Reduce the workload of the upgrade package generator. ...

Abstract

The invention relates to a method for solving the replay of the remote update of an information safety device, which comprises the following steps: a server combines and sends an update package and a time stamp TSb; a client receives and splits the combination, and judges whether the TSb is larger than a client time stamp TSa; and if the TSb is judged to be larger than the TSa, the upgrade package performs the update and updates the TSa with the TSb. The invention also discloses a system for solving the replay of the remote update of an information safety device. By using the embodiment of the invention, the replay of the information safety device is solved, and meanwhile, the workload at an update package generating end is reduced.

Description

technical field [0001] The invention relates to information security equipment upgrade technology, in particular to a method and system for solving the replayability of remote upgrade of information security equipment. Background technique [0002] Generally speaking, software upgrades can be performed through the Internet, which is convenient for users. However, the upgrade of hardware is usually done by mail. Due to geographical restrictions, it takes a few days for the user to get the new hardware, which is troublesome at the same time. Moreover, software protection products and other information security devices, as part of software products, update users' products by mail, which seriously affects the normal use of users. [0003] Therefore, many information security devices provide the function of remote upgrade. The remote upgrade of information security equipment generally includes the following process: [0004] 1. The upgrade package generator will encrypt and si...
