Embodiment Construction

[0034] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0035] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a business data signature system, such as figure 1 As shown, including: client 101 and digital authentication terminal USB_Key102;

[0036] The client 101 is used to send business data to USB_Key102 through the signature channel of non-transaction business;

[0037]The USB_Key102 is used to receive the business data sent by the client 101 through the non-transaction business signature channel; judge whether the digest algorithm format adopted by the business data belongs to the non-transaction business digest algorithm format; when the digest algorithm format adopted by the business data is not If it belongs...

Abstract

The invention relates to the technical field of information security, in particular to a service data signature method, a service data signature device, a service data signature system and a digital certification terminal. The method comprises the following steps of: receiving service data which is transmitted through a non-trading service signature channel from a client; judging whether a digest algorithm format adopted by the service data belongs to a non-trading service digest algorithm format or not; and if the digest algorithm format adopted by the service data does not belong to the non-trading service digest algorithm format, denying signature, wherein the non-trading service digest algorithm format and a trading service digest algorithm format are different. By the service data signature method, the service data signature device, the service data signature system and the digital certification terminal in the embodiment of the invention, potential safety hazards can be relatively better eliminated, and the legality and security of signature data can be ensured.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method, device and system for signing service data and a digital authentication terminal. Background technique [0002] As a personal identity authentication and digital signature terminal, USB_Key has been widely used in online banking, e-government and other fields. [0003] In recent years, with the vigorous development of the online banking market, USB_Key products tailored for online banking security transactions, with higher security, with key display function or key voice function, have appeared in the industry, and have been widely recognized. Most banks use promotions. At present, the second-generation online banking USB_Keys on the market are all based on the first-generation USB_Keys, which increase the security of transactions by man-made operations such as viewing display information and pressing keys during the transaction process. [0004] The spec...
