A key generation method, device, terminal and medium for a body area network

Abstract

The present application discloses a key generation method, device, terminal and medium for a body area network, including: acquiring biometric information of a user; using the biometric information to generate an encryption key and a decryption key for the body area network send the decryption key to the data receiving device, so that the data receiving device can use the decryption key to decrypt the obtained encrypted information sent by the terminal; wherein the encrypted information is obtained by the terminal using the encrypted information. information encrypted by the encryption key described above. The present application uses the biometric information of the user to generate the encryption key and decryption key of the body area network, and the encryption key and decryption key obtained in this way are unique to the user, which improves the security of the key. When the terminal initiates communication, the encryption key is used to encrypt the data to obtain encrypted information, and the data receiving device uses the decryption key to decrypt the obtained encrypted information, thereby ensuring the safe transmission of data.

Description

technical field [0001] The present application relates to the technical field of key generation, and in particular, to a key generation method, device, terminal and medium for a body area network. Background technique [0002] Wearable smart devices are widely used to collect human body data because of their portability and ease of operation. These wearable smart devices communicate through wireless technology and form a body area network together with mobile terminals, which can monitor and record human health signals for a long time. , providing data support for people's health and medical services. These terminals contain a large amount of user sensitive information when transmitting information. However, due to the characteristics of these terminals with various forms and differences in open connections, their data is vulnerable to attack or theft, and it is difficult to solve the problem of information security. Once the data is leaked or A malicious attack can have un...

AI Technical Summary

Problems solved by technology

These terminals contain a large amount of sensitive user information when transmitting information. However, due to the characteristics of various forms and open connection differences of these terminals, their data is vulnerable to attack or theft, and it is difficult to solve information security problems. Once the data is leaked or Malicious attacks can have unforeseen consequences

[0003] At present, in order to facilitate management, the existing technology generally uses unified key management for terminals, that is, the same manufacturer will use the same key for a large number of terminals, which reduces the security of keys and the security of data transmission. It cannot be guaranteed, and when users have problems, they need to contact technical personnel to solve them, causing a certain degree of trouble
