Ultra-lightweight encryption method suitable for WBAN data real-time encryption transmission

Abstract

The invention relates to an ultra-lightweight encryption method suitable for WBAN data real-time encryption transmission, and belongs to the technical field of wireless communication. According to the method, the random number extracted from the physical layer protocol data in the body area network protocol is introduced as the key parameter, and the private key is generated after the key parameter passes through the MD5 function to encrypt the key, so that the confidentiality of key transmission in asymmetric encryption is enhanced. According to the method, the problem that the secret key of the wireless body area network is acquired maliciously can be effectively prevented. Meanwhile, a secure channel is established through identity authentication, the transmission safety of the ciphertext in the channel is guaranteed, the node power consumption is greatly reduced, and the service life of a node battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an ultra-lightweight encryption method suitable for real-time encrypted transmission of WBAN data. Background technique [0002] In the body area network (BAN), due to the weak data carrying capacity and low node energy of the wireless body area network node equipment, it is difficult for the node to adopt the traditional complex encryption algorithm to ensure the security of data transmission. Therefore, the lightweight data encryption mechanism has become a wireless body area network. An important means of domain network security protection. [0003] With the rapid development and technological update of wireless communication, micro-electromechanical systems, and integrated circuit technology, the miniaturization and high integration of sensor devices have led to the rapid development of wireless sensor networks. Driven by new technologies, sensor nodes are devel...
