An enhanced encryption algorithm with key update scheme for Internet of Things
Hong Chen · Journal of Physics Conference Series · 2021
Abstract The protocols in the Internet of Things are more complex than the Internet. Once the Internet of Things devices have security problems, it will lead to a decline in user experience and huge economic losses. Therefore, this paper proposes a secure communication scheme for the Internet of Things based on a dynamic key update mechanism. This paper uses a variety of chaotic equations with good random characteristics to generate the session key library, and then uses the lightweight symmetric encryption algorithm Present-80 to encrypt the communication data. The simulation test results show that under the condition of ensuring communication efficiency, the security communication protocol of the Internet of Things based on the dynamic key update mechanism proposed in this paper has higher security.
