Homomorphic Traceable Encryption Model of Multi-Source Information in LAN PC Terminal
In order to solve the encryption problems caused by the large proportion of heterogeneous data from multiple sources and strong confusion ability,the paper presents a fully homomorphic traceability encryption model for multi-source information in LAN PC terminals.By utilizing the association rules and chaotic mapping trajectory points between multiple sources of data,a chaotic sequence was generated to capture the real-time state and associated data of multi-source information.A fully homomorphic traceability encryption framework was established by replacing the original source position matrix with a state position matrix and considering the source position changes during each iteration process.Based on the key characteristics of LAN PC terminals,hash functions,regional media parameters and security parameters were preset to generate high-strength public-private key pairs.By performing the homomorphic addition and multiplication operations,highly adapted ciphertext was generated.Experimental results show that the spatial distribution entropy of encrypted information elements is increased from 0.5 to 0.95.The proposed model has good encryption performance and can generate highly adaptable ciphertext,achieving accurate encryption of information.
