ENSURING INFORMATION SECURITY IN WIRELESS SENSOR NETWORKS

The problem of information security in wireless sensor networks is considered in this paper. An analysis of existing recommendations for information security in wireless sensor networks. It was found that one of the key problems of information security is the hardware limitations of the sensor nodes of the network. It is substantiated that the use of more complex cryptographic protection mechanisms will increase the load on the network. Safety requirements and their description are given. The main groups and types of information security threats in wireless sensor networks are considered. The classification of attacks and protection of wireless sensor networks according to the OSI model is presented. The existing solutions for information security are considered and analyzed. The shortcomings and vulnerabilities of the considered solutions are revealed. The method of public key cryptography is considered, the main advantages and disadvantages of this method are revealed. The analysis and comparison of ECC and RSA encryption methods are carried out. It is substantiated that the use of ECC in wireless sensor networks is more efficient than RSA. The method of cryptography with a symme
