PRIME protocol is a narrowband power line communication protocol whose security is based on Advanced Encryption Standard. However, the key expansion process of AES algorithm is not unidirectional, and each round of keys are linearly related to each other, it is less difficult for eavesdroppers to crack AES encryption algorithm, leading to threats to the security of PRIME protocol. To solve this problem, this paper proposes an improvement of PRIME protocol based on chaotic cryptography. The core of this method is to use Chebyshev chaotic mapping and Logistic chaotic mapping to generate each round of key in the key expansion process of AES algorithm, In this way, the linear correlation between the key rounds can be reduced, making the key expansion process unidirectional, increasing the crack difficulty of AES encryption algorithm, and improving the security of PRIME protocol.
