In this study, we develop a secure high-performance WSN, named the Secure and High-performance WSN based on Symmetric-key Matrix (SHWSM for short), which exploits a symmetric key as a channel key to improve the key-exchange performance of a network when a node is newly added to the network. We also use time key, random key, system group key, individual symmetric key and system group table etc, as the encryption parameters, and employ a two-dimension operation and dynamically accumulated shifting substitution technique to produce encryption keys and a verification key. The purpose is to ensure the security between the sender and receiver of a network connection. Theoretical analysis and simulation show that the SHWSM is a secure high-performance WSN.
