Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention 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.

[0042] It should be noted that information encryption is often used in information communication environments. For example, in the process of information communication, it is usually necessary to encrypt communication information to prevent communication information from being stolen by others. Of course, information encryption can also be used in non-information communication environments. For example, after encrypting the confidential information, it can prevent others from obtaining the confidential information by copying the mobile USB disk. However, the information encryption algorithm provide...

Abstract

The invention is applicable to the technical field of blockchains, and relates to an information encryption algorithm, an information encryption device, an information decryption algorithm, an information decryption device, and a communication method. The information encryption algorithm comprises the following steps of: encrypting to-be-encrypted data according to a hash value of a random numberto generate first encrypted data; encrypting the hash value of the random number according to a preset first user private key and a preset second user public key to generate second encrypted data; andcombining the first encrypted data with the second encrypted data to generate final encrypted data. According to the information encryption algorithm provided by the invention, only a first user public key and a second user private key can be used for decrypting the second encrypted data and acquiring the hash value of the random number for decrypting the to-be-encrypted data, thereby realizing decryption of the encrypted data; and the second user private key is only owned by a second user serving as an information receiving end, so that the security of communication information is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to an information encryption algorithm, a device, an information decryption algorithm, a device and a communication method. Background technique [0002] Information encryption has always been the focus of information security, especially in the process of information communication, in order to ensure communication security, it is usually necessary to encrypt communication information. [0003] At present, in the blockchain, the information on the chain is public, so that everyone can supervise each other and jointly maintain the data from being tampered with. This also means that confidential data on the chain will also be made public, that is, information leakage. The present invention can solve the problem of information leakage on the chain of confidential data without destroying the original block chain technical framework; it can also be used for off-chain encry...
