Secure And Efficient Transmission Scheme Based Oncompressed Sensing In Wirelesssensor Networks

With the rapid development of the information age,the Internet of Things technology has been seen everywhere,which involves more and more ethical and personal privacy issues.Therefore,the encryption and authentication technology in the Internet of Things is very important for personal privacy and security.As more and more data are transmitted,technology is restricted in wireless sensor networks with limited resources.Designing a safe and efficient transmission scheme has become one of the current research hotspots.Compressed sensing,as a technology capable of efficient transmission and encryption,is widely used in networks with limited conditions,but it still has certain limitations in terms of security,that is,the encryption mechanism lacks authentication and verification functions and cannot be resisted Man-in-the-middle attacks,such as counterfeiting,tampering,etc.Therefore,in wireless sensor networks that are getting closer to people's work and life,the security of traditional compressed sensing is limited.The introduction of digital signcryption solves the authentication and verification problems in traditional compressed sensing schemes.In response to the above problems,this article conducts in-depth research on the secure and efficient transmission scheme of compressed sensing based on digital signcryption and compressed sensing theories.The main research results and innovations of this paper are as follows:(1)A compressed sensing algorithm based on digital signcryption is proposed,which combines digital signcryption and compressed sensing,which reduces the amount of data transmission and provides authentication and verification functions for data transmission.This paper gives a detailed introduction to the proposed algorithm,and gives a verification of the correctness of the proposed algorithm.It is verified by simulation experiments that the proposed algorithm meets the validity requirements of data transmission,and can resist brute force attacks,statistical attacks,selected plaintext attacks and known plaintext attacks at the same time.(2)Based on the optimized P-tensor product compressed sensing,the proposed algorithm is applied to wireless sensor networks,and a safe and efficient transmission scheme of P-tensor compressed sensing based on digital signcryption is proposed.The details and details of the proposed scheme are introduced.Advantage.The simulation experiment verifies that the image restoration effect of the proposed scheme after optimization is higher than that of most compressed sensing schemes.At the same time,the correlation of ciphertext,histogram,and image entropy are studied to further verify that the security of the proposed scheme meets the requirements of secure data transmission.
