Abstract

The invention provides a private key, a public key and a decryption method. The private key comprises at least one permission label, a key granularity number and a key main body, wherein permission labeling information corresponding to each permission label is recorded in the permission label; the key main body comprises at least one key granularity; the number of the key granularities is recorded in the key granularity number; a coordinate value of a key space is recorded in each key granularity, each coordinate value corresponds to one space geometry in an encrypted space, and the encrypted space is provided by a public key corresponding to the private key. The private key can be a geometry key structure based on the space geometry, and thus, the private key is not related to a conventional mathematical encryption algorithm and is difficult to crack. Therefore, according to the scheme, transmission security of data files can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a private key, a public key and a decryption method. Background technique [0002] With the continuous development of computer hardware technology, especially the rise of quantum computer technology, the use of public and private keys to encrypt and decrypt data files can effectively guarantee the security of Internet data transmission. [0003] At present, the traditional AES (Advanced Encryption Standard, Advanced Encryption Standard) / RSA mathematical encryption algorithm can be used to encrypt and decrypt data files. [0004] However, the key system formed by the traditional mathematical encryption algorithm usually has a fixed algorithm mode, and different users and manufacturers must follow the same algorithm definition. Once the algorithm has a security risk or is cracked, its security is usually no longer Guaranteed. Contents of the invention [0005] The invention p...
