A Data Symmetry Algorithm-Based Security Awareness Model for Emergency Wireless Communication under Multisensor Fusion

Abstract

Due to the characteristics of sensor networks, wireless sensor networks (WSN) have a series of security threats in their applications. For example, wireless sensor networks are vulnerable to attacks such as eavesdropping, data tampering, and jamming. The processing capacity of sensor nodes is limited, and its integrity and confidentiality are greatly threatened. Nodes are easily captured or counterfeited; control of the energy of nodes; encryption and decryption of data depends on the distribution and management of keys; how to ensure the legal networking and access of nodes, etc. With the deepening and gradual promotion of WSN research, these security threats have become an urgent problem to be solved. In the context of multisensor fusion, this research realized the construction of a security perception model of emergency wireless communication based on the Bicycle data symmetric encryption algorithm and the use of secret sharing technology. The 16 bit Bicycle encryption and decryption time is about 1/40 of the encryption time, and the 32 bit Bicycle decryption time is about 1/30 of the encryption time, 16 bit encryption is slower than 32 bit encryption and faster decryption.
