Electronic signature having safety component arranged outside and signing on medium containing electronic component

Abstract

The invention provides an electronic signature having a safety component arranged outside and signing on a medium containing an electronic component. The electronic signature contains a safety component and an electronic signature body containing an interface component, an information processing component and a reading and writing module. The safety component carries out encryption algorithm processing on signing information by an encryption algorithm module by taking secret key information as the cipher to obtain ciphertext and the ciphertext information is transmitted to the information processing component by the interface component; the information processing component converts the ciphertext information into signing data written into the electronic component by the reading and writing module. By employing the technology of the invention, the uniqueness and the non-imitating characteristic of the signing information on the basis of the medium based electronic bill is improved, thereby enabling the use of the electronic bill to be safer. Due to adopting a way which is easy to identify and use to realize effective signing on the electronic bill, the risk of the electronic bill in use can be remarkably reduced, thereby promoting the development of modern financial industry.

Description

technical field [0001] The present invention relates to the electronic signature of an external security component for signing media containing electronic components, in particular to the electronic signature of an external security component for bill authentication that encrypts signature information and transmits it to electronic components embedded in the medium Electronic signature. Background technique [0002] With the development of modern economy, the healthy, orderly and safe development of the financial industry is of great significance to today's economic development. In the development of the financial industry, from cash transactions to the comprehensive popularization of various financial instruments, such as letters of credit, promissory notes, checks, etc., have become the main payment tools for various businesses in the modern economy. [0003] However, due to the value and circulation of financial instruments themselves, the security of financial instrumen...

Problems solved by technology

However, based on cost and technical reasons, the anti-counterfeiting marks of letters of credit, promissory notes, and checks are not complicated and can be easily copied by counterfeiters.

There are two problems in the signature or endorsement used to confirm the validity of letters of credit, promissory notes, and checks: on the one hand, the signatures or endorsements performed by the same person in different moods and at different time points cannot be guaranteed to be completely consistent, resulting in valid The signature or endorsement is rejected. On the other hand, because the signature or endorsement must be basically the same each time, it provides opportunities for counterfeiters to forge

For example, online banking and electronic key authentication technology to ensure the security of online banking are becoming an important direction for the development of the modern financial industry, but at the same time, network hackers, viruses, phishing programs, etc. also greatly threaten the security of online banking
