Abstract: Aiming at the problems of low network utilisation, poor security and high cost in the traditional intelligent test information security transmission method, a ZigBee communication-based information security intelligent detection and transmission method is proposed. Network key and connection key are realised by using asymmetric key system. Public key encryption and private key decryption are used to verify the trust centre. The sending node uses the trust centre to get the public key of the target node so as to achieve the goal of the intelligent test information security transmission. The simulation results show that the network utilisation rate is above 96%, compared with the traditional method, the index level has been significantly improved. The efficiency of the proposed method is up to 99%. In terms of cost, the proposed method has a lower cost. When the running time reaches 920 min, the cost is RMB 17,000 yuan.
