Electronic signature for continuously endorsing electronic paper through support of external security part

Abstract

The invention provides an electronic signature for continuously endorsing electronic paper through support of an external security part. The electronic signature comprises a security part and an electronic signature body, wherein the electronic signature body comprises an interface part, a message processing part, a reading module and a message sensing module. The message sensing module acquires remote holder endorsement signature data which is decrypted by the security part to obtain a remote holder signature message; an encryption algorithm module carries out encryption operation treatment on a signature message and the remote holder signature message by using a private key message of an endorser and a public key message of an endorsee as passwords to obtain a ciphertext message, and the security part transmits the ciphertext message to the message processing part through the interface part; and the message processing part converts the ciphertext message into signature data. The electronic signature improves the uniqueness and inimitability of the signature message and ensures that the use of the electronic bills is safer. The electronic signature adopts a mode which is easy to recognize and use to realize the effective signature of the electronic bills, thereby remarkably reducing the risk in using the electronic bills and promoting the development of modern financial industry.

Description

technical field [0001] The present invention relates to an electronic signature that an external security component supports continuous endorsement and signature of an electronic component, in particular to an external security component that encrypts the continuous endorsement signature information of the endorsement and then transmits it to an electronic component embedded in a medium such as a radio frequency electronic tag for bill authentication. Electronic signatures for security components. 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. However, d...

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
