Electronic seal system, electronic seal and electronic signature method

Abstract

The invention discloses an electronic seal system, an electronic seal and an electronic signature method and relates to the technical field of computer information security. The electronic seal system comprises an electronic seal and an electromagnetic screen, wherein the electronic seal is used for storing seal images and private keys and transmitting the stored seal images and private keys to the electromagnetic screen; and the electromagnetic screen is used for signing in a data message according to the received seal images, generating a digital certificate according to the received private keys, and transmitting the digital certificate serving as sealed data message authenticity verification information. The electronic signature method comprises that: the electronic seal transmits thestored seal images and private keys to the electromagnetic screen; the electromagnetic screen seals in the data message according to the received seal images, generates the digital certificate according to the received private keys, and uses the digital certificate as the sealed data message authenticity verification information. The electronic seal system, the electronic seal and the electronic signature method prevent viruses, Trojans and other malicious programs from stealing the private keys in an operating system and application software.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to an electronic seal system, an electronic seal and an electronic signature method. Background technique [0002] With the development of Internet technology and the rise of e-government and e-commerce, a large number of electronic documents (official documents, contracts, etc.) need to be transmitted or exchanged between different users through the network. How to ensure the authenticity and integrity of electronic document content is a technical problem that needs to be solved in the field of computer information security technology, especially in e-government and e-commerce. At present, the methods to solve such problems can be roughly divided into two categories: one is digital signature based on document content, and the other is electronic signature based on watermark technology. An electronic signature refers to the data contained in electronic form in...

Problems solved by technology

[0008] However, there are some shortcomings in digital signatures: first, digital signatures are affected by the operating system and application software, and the private key is read by software, which is easily intercepted by malicious programs such as viruses and Trojan horses, which eventually leads to the failure of digital signatures; second, the current electronic seal The device or method does not conform to the shape and external structure of traditional seals, and it is not compatible with the use of traditional seals

The shape of the seal has been established in the minds of people for thousands of years, especially in the minds of Asian people. It is not easy to be accepted by most people when it is suddenly replaced by a pure password or USB-key; thirdly, the current electronic seal The device or method does not have the feeling of "stamping" of traditional seals, and does not use the promotion of electronic seals
