Two-dimensional Code One-way Transmission System Based on Secret Sharing
With the rapid development of the Internet,people generally use electronic means to store and transmit important information in enterprises and units,which effectively improves work efficiency.Information and data of different security levels need to be shared in the internal network of classified units.In order to resist the risk of malicious attacks from low-level departments,mandatory access control or one-way transmission can be used to ensure the security of high-level information meet the requirements of information sharing.Secret sharing is a mechanism that splits a secret message into several parts and distributes these parts to different participants,and only when a sufficient number of participants cooperate,the complete secret message can be recovered.This mechanism can effectively manage secret information,improve the security and integrity of information,and prevent the abuse of rights.Shamir secret sharing algorithm is combined with two-dimensional code one-way transmission to design and implement the system.The two-dimensional code encoding process increases the encryption function of data,there is no interaction between the sender and the receiver,and there is no interaction between the data.It realizes strong physical isolation,and improves the security of information sharing from high level departments to low level departments in the classified network.The system can share secrets in the form of Chinese and English text and pictures.At the same time,the acoustic channel feedback mechanism is added to improve the reliability and practicability of the system.
