Embodiment Construction

[0074] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.

[0075] The foregoing content of the invention will be described in detail below through one of the examples.

[0076] combine figure 1 The light-weight communication method with user privacy protection function mentioned in the present invention includes five aspects: registration, login, key agreement, key confirmation, session fake identity update, and user password modification.

[0077] 1. Registration

[0078] Step 1: User chooses his own ID i Password PW i and a random number r i And calculate the false password as SPW=h(r i ||PW i ), fake identity PID i =h(r i ||ID i ). User will register request info {spw i ,PID i ,ID i} to the medical server, the communication channel at this stage is safe.

[0079] Step 2: After receiving the registration information, the medical server sel...

Abstract

The invention discloses a lightweight communication method with a user privacy protection function. In a registration phase, privacy registration of user identity information is completed through a first long-time private key set by a user and a second long-time private key set by a medical server. In a session phase, a first short-time private key set by a user and a second short-time private keyset by a medical server are combined with identity information stored in respective databases and timestamps for sending messages to complete verification of message communication security, and meanwhile, a session key formed by combining the first short-time private key and the second short-time private key is adopted to ensure secure transmission of medical data in a session stage.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a lightweight communication method with a user privacy protection function. Background technique [0002] In electronic health (e-health) systems, patients can be transferred from the hospital ward to the home, making e-health more and more popular. Electronic health systems have many applications such as home health monitoring, personal health records (PHR), etc., which facilitate the management of chronic diseases and enable patients to self-care. Over the past decade, Internet-enabled terminals with smaller sizes have replaced older desktops and medical devices. With the advancement of IoT technology, various handheld and wearable devices such as tablets, smart watches, and smart bracelets can act as communicators, sensors, and monitors. These devices are deployed on the patient's body or in the surrounding environment, collect real-time data of the patient, transmit it to...
