Computer safe login method

Abstract

The invention provides a computer safe login method. The method comprises the following steps: transmitting a radio frequency identification technology RFID tag to an authentication center through a reader-writer for identity authentication; after the identity verification is passed, performing data encryption transmission by using a Trivium algorithm; carrying out data decryption by using a Trivium algorithm; enabling the authentication center to communicate with the to-be-accessed computer, unlocking the to-be-accessed computer according to the user information and the access permission of the RFID tag, and opening a corresponding permission folder. According to the method, safe and credible application is achieved with low cost, and technical popularization is easy; a unique identity authentication mechanism is used, and the safety of the RFID tag and the reader-writer is guaranteed through two-way authentication; an extensible markup language (XML) is adopted as a storage information format, data expansibility is facilitated, an integrated compression algorithm is adopted for sending data, capacity expansion is facilitated, and a referential scheme is provided for large-capacity data transmission.

Description

technical field [0001] The invention relates to the technical field of data protection, in particular to a method for securely logging in a computer. Background technique [0002] Since the International Telecommunication Union proposed the concept of the Internet of Things, related technologies of the Internet of Things have been widely concerned. Radio Frequency Identification (RFID) is an important technology for implementing perception in Internet of Things applications. RFID technology is a communication technology that identifies specific targets and reads and writes relevant data through radio signals. This method does not require mechanical or optical contact between the identification system and specific targets. It has high accuracy, long service life, low cost, and high temperature resistance. It has been increasingly used in anti-counterfeiting, payment or ticket issuance, book management and multimedia teaching management and other scenarios. [0003] At presen...

Problems solved by technology

With the in-depth promotion of RFID technology, its privacy and security issues have become increasingly prominent. Since the general RFID tag directly responds to the query of the reader without the permission of its owner, if the user has a product with an unsafe tag, Then it may be read by a nearby reader without the user's perception, and the risk of illegal embezzlement of user sensitive information or location information is extremely high

[0004] In the actual application of RFID, there are potential safety hazards in RFID tags, networks, data and other links. The reader, RFID tag and data collection end are called the front-end data collection part, and the communication between the data collection terminal and the background data processing is called Back-end data transmission, most of the current research work is concentrated on the front-end data acquisition part, but the security risks in data transmission can still cause major losses

In order to solve the security risks brought by computer login authentication, the industry usually integrates dedicated security hardware circuits, FPGA chips or security SOC chips. In terms of promotion, especially the implementation of security certification for general-purpose computers, it is facing huge cost pressures
