Problems solved by technology

[0009] In the past, the authentication technology of smart wearable devices was only based on central authentication. There were few authentication methods, complex schemes, and information such as physiological characteristics were easily leaked and tampered with, so there were hidden dangers in terms of security.

Embodiment Construction

[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] A blockchain-based security authentication method for vehicle-mounted smart wearable devices, which includes a registration process and an authentication process;

[0029] The registration process described includes:

[0030] S11. The nodes in the blockchain network input the node identification number and the corresponding password at the terminal, and at the same time, the physiological collection module extracts physiological characteristics;

[0031] S12. The node uses data conversion technology to process the input physiological characteristics, uses the secret key generator to generate random key M and data D, and performs hash operation on the password...

Abstract

The invention discloses a security authentication technology for an intelligent wearable device, a design method and a new mechanism with a block chain technology and the security authentication technology combined. The previous intelligent wearable device authentication technology is only based on central authentication, which has hidden dangers in aspects of loss prevention, tampering preventionand anti-counterfeiting security. The security authentication scheme disclosed in the invention comprises distributed central nodes such as a cloud platform, a vehicle, an intelligent wearable deviceand a customized APP, and has the characteristics of unified maintenance and tampering prevention, user data leakage, user mobile phone and intelligent device loss and forgery platform attacks can thus be prevented, and multiple entity authentication security attributes are achieved. The security authentication technology has the advantages of simple structure, flexible design, good security performance, and can effectively reduce the complexity of implementation of the intelligent wearable device.

Description

technical field [0001] The invention relates to a safety authentication method for a vehicle-mounted smart wearable device based on a block chain. Background technique [0002] A blockchain is a specific data structure in which blocks of data are combined in a chain in chronological order and in a cryptographically guaranteed undecipherable and unforgeable decentralized public record. In blockchain technology, data is permanently stored in blocks. Each block is generated in chronological order and connected through a chain structure to form a blockchain. A block consists of a block header and a block body. [0003] The block header encapsulates the version number, timestamp, the address of the previous block, the hash value of the current block, the total hash value of transaction data, and relevant data participating in the consensus mechanism. The hash value of the previous block is a hash operation of each module data of the previous block header, and these blocks are ...
