A Lightweight Messaging Approach for End-to-End Smart Device Communication in IoT Cloud

Abstract

The invention provides a lightweight message delivery method for end-to-end intelligent device communication in the Internet of Things cloud. In the Internet of Things-cloud computing system, the message delivery method includes two processes of registration and key agreement, and lightweight secure message delivery, with functions of secure key and biometric parameter exchange, biometric shared parameters, and biometric key generation functions, lightweight end-to-end smart device communication negotiation functions, and lightweight messaging functions. The present invention adopts the elliptic curve encryption algorithm to apply the secure exchange of the security key and the user's biometric parameter to the communication process, thereby performing mutual authentication of responses to prevent attacks and ensure communication security. The present invention also integrates the shared key and the temporary session key into the random map, generates the sum of the message verification code and hides it in the cover image to verify the source of the sender's message transmission, and realizes a secure and low-complexity end-to-end Smart device messaging capabilities to maintain authentication and integrity of messages.

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...
