Lightweight message transmission method for end-to-end intelligent device communication in Internet of Things cloud

Abstract

The invention provides a lightweight message transmission method for end-to-end intelligent device communication in Internet of Things cloud. In the Internet of Things cloud computing system, the message transmission method comprises two processes of registration and key negotiation and lightweight security message transmission, and has a security key and biological characteristic parameter exchange function, a biological shared parameter and biological key generation function, a lightweight end-to-end intelligent device communication negotiation function and a lightweight message transmissionfunction. According to the invention, the elliptic curve encryption algorithm is adopted to apply the security exchange of the security key and the biological characteristic parameters of the user tothe communication process, so the mutual authentication of response is carried out to prevent attacks and ensure the communication security. In addition, the shared secret key and the temporary session secret key are integrated into random mapping, the message verification code sum is generated and hidden in the cover image to verify the message transmission source of the sender, the safe and low-complexity end-to-end intelligent device message transmission function is achieved, and authentication and integrity of the message are maintained.

Description

technical field [0001] The invention relates to the field of message delivery methods, in particular to a lightweight message delivery for end-to-end smart device communication in the cloud of the Internet of Things. Background technique [0002] With the rapid development of information technology and network technology, the problems exposed in information security are also emerging one after another. In the prior art, in order to achieve secure message transmission, encryption algorithms are mostly used to encrypt messages before transmission, but in order to achieve sufficiently secure encryption and decryption, too many resources will be consumed, and once the encryption key is leaked, the transmitted The messages will all be deciphered. [0003] The invention patent with the application number CN201510019460.3 discloses a secure messaging method based on a trusted architecture. It consists of three parts: trusted bus, component nodes and security mechanism, in which c...
