Embodiment Construction

[0026] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] A sound encryption system and current cryptography principles are the foundation for alliance chains to ensure information reliability and asset security. In the coming era of quantum computing, there are many loopholes in the traditional encryption system and cryptography principles, which can theoretically be broken by quantum computing, making the application of the alliance chain worthless. The present invention intends to use an algorithm that can resist quantum attacks to design a more com...

Abstract

The invention discloses an alliance blockchain underlying encryption method capable of resisting quantum attacks. According to the method, a set of identity and message verification process is adopted, in the links that may be broken by hackers through quantum computing or other means, such as the link of issuing digital certificates, the link that nodes access a transaction platform, the link that the nodes perform transactions, and the link that the transaction contents are transmitted between the nodes, an NTRUsign algorithm that resists the quantum attacks is adopted to generate signaturesor verify the signatures, the verification of the identity and information security can be strengthened, so that the alliance chain can resist the attacks of quantum computing on the whole, and the alliance chain can still have strong vitality in the future quantum computing era.

Description

technical field [0001] The present invention relates to the digital signature technology in the block chain and its application, in particular to an encryption method at the bottom of the alliance block chain that can resist quantum attacks. Background technique [0002] Consortium chain technology is based on blockchain technology, and it mainly provides enterprise-level blockchain network solutions for the blockchain technology needs of large companies, government agencies and industry alliances. This technology is an extended application of blockchain technology. Its essence is also a distributed data storage protocol. It can safely store transaction information or other data, and has guarantees that the information cannot be forged or tampered with. The confirmation and recording of each transaction requires the participation of all nodes, and a consensus algorithm ensures the validity and correctness of the data. Every transaction has traceability, and each participa...
