Mainframe security protection method based on embedded type

Abstract

A mainframe security protection method based on the embedded type includes the following steps of firstly, placing an MBR in a sector of an ARM, randomly generating a 512B character string, conducting step-by-step encryption on the 512B character string and a 512B MBR, and generating a new 512B character string; secondly, conducting step-by-step decryption calculation through the random character string and the encrypted MBR character string during decryption, and then conducting decryption through combination with an encryption algorithm in the first step to obtain a true MBR; thirdly, generating a character string when a fingerprint verification module runs for the first time, storing the character string in some preset sector on the ARM, comparing the character string with the character string which is stored in the designated sector of the ARM at the first time when the fingerprint verification module runs, and generating a new random character string after verification so that dynamic encryption and decryption can be achieved; fourthly, transmitting 512 characters to the designated position of the MBR before entering a computer, loading the true MBR onto the designated sector, and powering on the computer; fifthly, if a mainframe is in the standby state, and inputting fingerprint information again according to a Windows message responding mechanism and all operations which are conducted on the main frame by the program Hook so as to obtain operation permission, thereby improving security greatly.

Description

technical field [0001] The invention belongs to the technical field of host security protection, and in particular relates to an embedded host security protection method, which is used for security protection of the host before and after startup. Background technique [0002] In current personal computer applications, the method of user ID+password is mostly used for user identity authentication and access control. However, if the password is forgotten or stolen by others, the security of the computer system and files will be threatened. The biometric-based authentication system is a research hotspot in the field of information security because of its uniqueness, and many operation authorization verification methods are adopted. However, since the operation of the above authentication systems is established after the host system is started, for professional technicians, they all have the ability to break through the verification process, so the safety factor is not relative...
