Embodiment 1

[0036] This embodiment provides a method for communicating between a smart key device and a computer, see figure 1 , the method includes the following steps:

[0037] Step S102, the smart key device receives the communication request instruction sent by the computer, wherein the communication request instruction carries the user's personal identification code, the number of loop iterations and a predetermined byte length (that is, the predetermined length of the generated message key );

[0038] Step S104, the smart key device searches for the user's personal identification code according to the above-mentioned personal identification code; the corresponding relationship between the personal identification code and the personal identification code has been stored in advance on the smart key device, so that no smart key is needed The personal identification number is transmitted between the device and the computer, which enhances the security of the system.

[0039] Step S106...

Embodiment 2

[0076] see figure 2 , which is a flow chart of a method for communicating between a smart key device and a computer provided in this embodiment. In this embodiment, a USB Key is used as an example of a smart key device for specific description. The method includes the following steps,

[0077] Step S201: the computer sends a request instruction for establishing communication to the USB Key;

[0078] Preferably, the data field of the request instruction includes: a personal identification code identifier, which indicates the personal identification code that needs to be referenced, waiting for the user to input, and also includes a loop iteration number M and a predetermined byte of the message key Length L1.

[0079] Wherein, the number of loop iterations is used to increase the cost of generating the key from the one-time personal identification code, thereby increasing the difficulty of the attack; in this embodiment, the number of loop iterations M can be selected to be n...

Embodiment 4

[0172] Embodiment 4 provides a system for communicating between a smart key device and a computer, see Figure 6 , the system includes: a smart key device 62 and a computer 64;

[0173] Wherein, computer 64 comprises:

[0174] The command sending module 642 is used to send a communication request command, wherein the communication request command carries the user's personal identification code, the number of loop iterations and a predetermined byte length;

[0175] The personal identification code acquisition module 644 is connected with the instruction sending module 642, and is used to obtain the personal identification code according to the identification of the personal identification code;

[0176] The second key generation module 646 is connected with the personal identification code acquisition module 644, and is used to generate the second message key according to the personal identification code, the number of loop iterations and the predetermined byte length;

Abstract

The invention provides a method and a system for intelligent secret key equipment to communicate with a computer. Wherein the method comprises that the intelligent secret key equipment receives a communication request instruction sent by the computer, wherein the communication request instruction carries the personal identification code identification of a user, a cycle iteration frequency and a determined byte length; the intelligent secret key equipment searches the personal identification code of the user based on the personal identification code identification; the intelligent secret key equipment generates a first message secret key based on the personal identification code, the cycle iteration frequency and the determined byte length and the computer generates a second message secret key based on the personal identification code, the cycle iteration frequency and the determined byte length; the intelligent secret key equipment communicates with the compute respectively using the first message secret key and the second message secret key. According to the invention, the problem that hidden troubles exist in transactions between the intelligent secret key equipment and the computer is solved, the security of the system is enhanced and the benefit of the user is guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for communicating between an intelligent key device and a computer. Background technique [0002] With the development of the Internet, e-commerce and e-government, more and more attention has been paid to the problems of network security. USB Key (smart key device) is gradually becoming the mainstream solution for high-end e-commerce such as online banking. Identification and data protection play an increasingly prominent role. At the same time, the security of computer communication system is a major event related to human life and survival, and has become an important issue of concern to all countries in the world. It has become an important research topic in the field of network security and information security. As we all know, in the existing communication methods, the communication method of USB technology is based on the communication method of the ...
