Identity authentication and data security transmission method in medical sensor network environment

Abstract

The invention provides an identity authentication and data security transmission method in a medical sensor network environment. The method comprises the following steps: initialization: enabling a background server to initialize a medical sensor network; a registration stage: registering the medical sensor nodes and medical workers in a background server; a login stage of a user: identity verification and key negotiation: after an authentication request sent by the user is received, enabling the background server to verify the legality of the user and negotiate with the user to generate a communication key after successful verification; and secure transmission of the data: enabling the user to obtain the medical data of the patient from the background server, or directly communicate withthe medical sensor node to obtain the stored medical data of the patient. According to the invention, it is ensured that medical data of a patient can be safely transmitted to the background server, and it is also ensured that the data is only read by legal medical workers, so private data of the patient is not leaked; identity verification based on the temporary value can ensure the integrity andverifiability of the identity of the authenticated user.

Description

technical field [0001] The present invention relates to the technical field of mobile network computing, in particular to an identity authentication and data security transmission method in a medical sensor network environment, which realizes user identity authentication based on a public key encryption algorithm and a bilinear pairing algorithm, and based on a symmetric encryption algorithm Realize the secure transmission of medical data. Background technique [0002] In recent years, with the rapid development of wireless communication technology and microelectronics technology.
