Method for creating public key encryption and key signature, apparatus, and readable storage medium

Abstract

The invention discloses a method for creating a public key encryption and key signature of a block chain, comprises: step S101, constructing a function so as to encrypt data under a public key, creating a message by the party owning the converter, decrypting only the recipient using the public key, and decrypting only the corresponding secret key which cannot be obtained from the calculation of the public key, thereby realizing the public key encryption creation of a block chain; step S102, selecting a secret value different from the of the public key encryption of the block chain, and sharingthe secret value for all the converters, so that the other parties can not know, and verifying whether the proxy checks whether the signature format is correct and/or whether the signature is equal to another signature obtained by other means through the hashing operation and verification steps. Also disclosed are corresponding devices and readable storage media. The technical proposal of the present disclosure uses only symmetric encryption and a hash function to securely exchange keys, thereby creating cryptographic proof of authenticity, integrity, and non-repudiation in a basic and efficient manner, which cannot be reverse engineered.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, device and readable storage medium for creating public key encryption and key signature. Background technique [0002] The Shor algorithm is very important. It represents the use of quantum computers, which can be used to crack the widely used public key encryption method, that is, the RSA encryption algorithm. The basis of the RSA algorithm is to assume that we cannot effectively decompose a known For integers, Shor's algorithm shows that the factorization problem can be solved efficiently on a quantum computer, so that a sufficiently large quantum computer can crack RSA. At present, the Shor algorithm has greatly promoted the development of quantum computers, and also promoted the physical realization of quantum computers. This algorithm does not guarantee that every operation can get the correct result, but it can increase the probability of success of ...

Problems solved by technology

However, these do not directly address the problem, as these clearly do not provide clear alternatives

In addition, most of the work is devoted to lattice-based cryptography, which is considered the most promising asymmetric cryptographic solution, however, it does not use the underlying cryptography, which increases the complexity of the scheme
