One-way secure data transmission method based on a public key password

Abstract

The invention discloses a one-way secure data transmission method based on a public key password, and belongs to the technical field of public key password systems and secure data transmission. The method comprises the steps that on the basis of public key encryption, a public key is preset in data acquisition equipment, a private key is preset in service main equipment, and after configuration ofthe data acquisition equipment and the service main equipment is completed, the data acquisition equipment is configured to a data acquisition point to start a data acquisition mode for data acquisition work; The service main equipment is networked with the data acquisition equipment at the data acquisition point within the maximum working time range of the data acquisition equipment, and the data acquisition equipment starts a data sending and receiving mode to upload the data to the service main equipment. According to the method, the risk caused by the fact that all encrypted data are encrypted by the same secret key only by using the AES fixed secret key is solved; The efficiency is improved; The risk of key exposure is effectively avoided; And a security mechanism of one-time encryption is adopted, so that the data and the encryption key of the sending host are securely stored and transmitted.

Description

technical field [0001] The invention relates to a one-way secure data transmission method based on public key cryptography, belonging to the technical field of data secure transmission. Background technique [0002] With the increase in the number of sensor devices, smart wearable devices and their auxiliary equipment, the complexity of usage scenarios increases, the amount of data collection increases, the randomness of function activation increases, and the uncertainty of network connections with service master devices increases , all of which have higher requirements for the safe collection and storage of data by the above-mentioned equipment, and the safe and fast transmission of data to the main service equipment. In order to enable the data collection terminal carried by the above-mentioned equipment to encrypt and protect the collected data by using symmetric encryption method from the beginning of data collection, and to enable the service master device to safely rec...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of one-way secure data collection and one-way data transmission to the service main equipment of sensor equipment, smart wearable equipment and its auxiliary equipment. The existing technology cannot realize safe collection of data and encrypted storage data under offline conditions. When the network conditions are met and there is no external one-way physical transmission equipment support, the technical defect of completely relying on cryptography to achieve one-way secure data transmission, a method for one-way secure data transmission based on public key cryptography is proposed.
