Abstract

The invention discloses a certificate-free anonymous authentication method for a wireless body area network, which mainly solves the anonymity problem of wireless body area network remote authentication, and mainly comprises the steps as follows: 1) a network manager initializes a whole wireless body area network system; 2) a wireless body area network user carries out identity register from the network manager; 3) the network manager issues an account index to the wireless body area network user; 4) the wireless body area network user uses the account index to disguisedly send a service request to the network manager; and 5) bidirectional authentication between an application service provider and the wireless body area network user is achieved. According to the invention, a certificate is not required, the defect of no key escrow is avoided, the security performance is high, the degree of complexity of calculation is low, and the method can be used for remote medical treatment monitoring and on other application occasions.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to certificateless remote anonymous authentication of a wireless body area network, which can be used for monitoring and managing remote patients' physical conditions. Background technique [0002] The management of remote patients' physical conditions and health crisis detection, so that patients can obtain the greatest freedom of mobility, has always been more concerned by people. In recent years, the application of wireless body area network in remote medical monitoring has attracted widespread attention at home and abroad. The wireless communication technology is used together with the wireless body area network system, and the collected physiological information is transmitted to remote medical sites by wireless transmission by arranging various wireless body area network nodes on the patient's body, such as health care centers, medical The site provid...
