Abstract

The invention discloses a password protection method, and provides a password protection method aiming at the problem that a plurality of passwords can be invalid after one password is broken when the plurality of passwords are used at present. The specified bit of the password failure enabling identifier stored in the storage medium is determined, and due to the fact that only one password passes through authentication, only one specified bit exists; the designated bit is set to be in an allowed state, other bits are set to be in a non-allowed state, the password failure enabling recognition is in one-to-one correspondence with the passwords according to bits, and only when one bit of the password failure enabling recognition is in the allowed state, failure operation on the passwords is allowed; judging whether a password failure request is received or not; and when a password invalidation request is received, performing invalidation operation on the password corresponding to the specified bit. Therefore, only one password can be invalid in one-time login, and the problem that all passwords can be invalid after one password is cracked is solved.

Description

technical field [0001] The present application relates to the field of integrated circuit design and application, in particular to a password protection method, device and medium. Background technique [0002] In actual production and life, in order to ensure safety, passwords are usually set on the chips of some electronic devices in need. The problem that it is easy to be cracked and the device is no longer safe after a single password is cracked is currently usually solved by adding multiple passwords or root passwords. [0003] In recent years, the method of adding multiple passwords or root passwords is usually used to solve the problem of a single password. However, when using multiple passwords, the multi-password invalidation mechanism does not take into account the situation of invalidating multiple passwords at a time. Afterwards, all passwords can be invalidated, resulting in the failure of the chip and the system. [0004] Therefore, now those skilled in the ar...
