Heterogeneous sensor network encryption protocol based on chaotic neural network public key encryption algorithm

Abstract

The invention discloses a heterogeneous sensor network encryption protocol based on a chaotic neural network public key encryption algorithm; the public key encryption algorithm based on the chaotic neural network is combined with characteristics of a heterogeneous sensor network, thus designing a novel encryption protocol suitable for the heterogeneous sensor network; the encryption protocol specifically comprises the following steps: building a base station layer and a cluster head layer secrecy communication network; building a cluster head layer and a perception layer secrecy communication network; updating a cluster head layer secret key; updating a perception layer secret key; adding a novel cluster head node; adding a novel perception node; quitting the cluster head node; and quitting the perception node. The encryption protocol can flexibly apply a public key code system into the sensor network, thus solving the problems that when a sensing node storage room and the calculation ability are different in the heterogeneous sensor network, only the secret keys with the same secret key room size can be fixedly used to encode data; the heterogeneous sensor network encryption protocol can improve network safety and encryption flexibility.

Problems solved by technology

However, early researchers generally believed that public-key cryptographic operations with high computational complexity are not suitable for sensor networks.

As a result, public key cryptography, a technology that can well solve the problems of key distribution in sensor networks, has not been valued by researchers for a long time.
