Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0023] Referring first to FIG. 1 . Fig. 1 has described the processing flow to the BOOTROM startup password of switch and super password in the preferred embodiment of the present invention:

[0024] If the system administrator has set a password for the switch, in order to gain control over the boot program file system of the switch, the correct BOOTROM startup password set by the administrator must be entered to enter the boot program file system of the switch and realize the control of the switch. Operation of files in FLASH ROM; if the BOOTROM startup password set by the system administrator is lost, then according to the unique identification MAC address of the network device, obtain the super password, and enter the boot program file system of the switch by entering the super password. There is no essential difference in functionality between the ...

Abstract

This invention provides a method for generating dynamical superencryption and using the superencryption to make security management to the exchanger. The method for generating dynamical superencryption is: reads MAC address of the device, according to the above MAC address and encryption algorithm generates the dynamical superencryption, stores the dynamical superencryption. The method for using the above dynamical superencryption to make security management to the exchanger is: B1. inputting start cipher; B2, the system decides if the start cipher is correct, if yes, then enters to the step B4, if no, then enters into step B3; B3, inputting superencryption; B4, enters into bootstrap program file system. The invention can make the configuration simpler after the cipher is lost, can effectively eliminate a series trouble caused by losing the multiple cipher of exchange.

Description

technical field [0001] The invention relates to a network equipment security guarantee technology, in particular to a switch security management method. Background technique [0002] With the rapid development of Ethernet, large-scale construction of metropolitan area networks and enterprise networks has been invested in various places. Ethernet switches have been widely used due to their unique line-speed forwarding performance, so the security issues of switches are becoming more and more popular. People's concern, which also includes the security management of switches. In order to improve the security performance of the switch and better meet the needs of users, dual password protection is generally set for the management of the switch: the first password is the BOOTROM (bootloader) startup password, that is, when the device starts To operate the boot program file stored in FLASH ROM (flash memory), password identification must be performed; the second password is the s...
