Embodiment Construction

[0037] The embodiment of the present invention provides a smart contract encryption method and device based on the triple MD5 encryption algorithm, which can make it impossible for the signatory to deny the signed electronic contract, and prevent others from pretending to be his own signature. Therefore, the electronic contract and the signatory are one and the same. One-to-one correspondence, so that the smart contract takes effect.

[0038]In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in ...

Abstract

The embodiment of the invention discloses a triple MD5 encryption algorithm-based intelligent contract encryption method and device. When the embodiment of the invention is applied to encryption of an electronic contract, the transaction cost can be reduced; a signer and encryption of the electronic contract are in a one-to-one corresponding relation, so that an outsider cannot alter the electronic contract, and persons in the contract cannot repudiate a debt; meanwhile, the method and the device can be applied to blockchain technology in the future and also used in many Internet-based transactions. Particularly, the MD5 encryption algorithm is relatively high in security; when the MD5 encryption algorithm is applied to the electronic contract, digital signatures, file completeness verification, password encryption and the like can be realized.

Description

technical field [0001] The invention relates to the field of smart contract encryption, in particular to a smart contract encryption method and device based on a triple MD5 encryption algorithm. Background technique [0002] After entering the 21st century, Internet technology became popular, digital currency based on the Internet and digital encryption technology emerged, and some underlying technologies related to it, such as blockchain technology and distributed bookkeeping methods, came one after another. Digital currency not only has the same credibility as banknotes, but also can further reduce operating costs. Behind it is a decentralized mechanism, which mainly establishes a trust system through distributed accounting methods. A complete blockchain application includes four key technologies: super ledger, smart contract, privacy protection and consensus algorithm. It can ensure the safe transfer of commercial assets, protect the core business of enterprises, store co...
