Embodiment Construction
[0028] Such as figure 1 As shown, the implementation steps of the password-based process authentication method in this embodiment are as follows:
[0029] 1) Set the authentication password for the process, calculate the HMAC value of the process according to the authentication password and store it in the extended attribute of the process; set the password acquisition control switch in the operating system in advance, and configure it according to the startup parameters of the operating system or the settings of privileged users The password obtains the status of the control switch; after receiving the operation request of the process, jump to the next step;
[0030] 2) Determine whether password verification is required according to the password acquisition control switch. When password verification is required, the authentication password is obtained, and the HMAC value of the process is calculated based on the authentication password. The calculated HMAC value and the HMAC...

The invention discloses a progress authentication method based on a password. The method comprises the following steps: setting an authentication password for a progress, calculating the HMAC value of the progress according to the authentication password and storing the HMAC value in extended attributes; presetting a password acquisition control switch in an operating system and configuring password acquisition control switch states; after receiving an operation request of the progress, judging whether to check the password according to the password acquisition control switch, acquiring the authentication password if needing to check the password; calculating the HMAC value of the progress based on the authentication password, comparing the HMAC value obtained by calculation with the HMAC value in the extended attributes of the progress, judging that the password authentication of the progress is successful and continuing the operation request of the progress if the HMAC values are the same, otherwise rejecting the operation request of the progress. The method disclosed by the invention has the advantages of reducing the risk of falsification of the system progress and being high in safety, good in universality and high in extensibility.
Description
technical field [0001] The invention relates to the field of computer security, in particular to a password-based process authentication method. Background technique [0002] At present, with the continuous deepening of informatization, computer viruses such as viruses, Trojan horses, and worms are increasingly damaging information systems. How to protect information systems from damage is imminent. Through analysis, it can be found that almost all computer viruses are caused by users executing malicious programs intentionally or unintentionally. Malicious programs usually pretend to be normal programs or are bound to normal programs, inducing users to execute tampered malicious programs to achieve the purpose of destruction. Therefore, the installation and operation of software with potential safety hazards can easily damage the security of the information system, at least it will damage the stability of the system, affect the normal operation of the system, and at the wor...
