The reason of doing is like this because local zone time is recorded in CMOS(Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor (CMOS)) in, can distort by removing CMOS battery or software, so local zone time is also unreliable, need to obtain the more reliable current network time as current time.
In the time obtaining current time success, described encryption apparatus obtain the initial time of the described BIOS cryptographic validity of storing in described FLASH, described BISO cryptographic validity and described BIOS cryptographic validity exceed the time limit remind state, described in exceed the time limit remind state comprise opening and closing.
Then, described encryption apparatus calculates the time interval between described current time and the initial time of described cryptographic validity.
Whether described encryption apparatus is greater than described BIOS cryptographic validity according to the described time interval, judges whether described BIOS cryptographic validity exceeds the time limit.
Concrete, if described interval greater than described BIOS cryptographic validity described encryption apparatus judge that described BIOS cryptographic validity exceeds the time limit, if the described time interval be not more than described BIOS cryptographic validity described encryption apparatus judge that described BIOS cryptographic validity does not exceed the time limit.
In the time that described cryptographic validity exceeds the time limit, described encryption apparatus is removed described BIOS password.
In the time that described cryptographic validity does not exceed the time limit, the described BIOS password of described encryption apparatus prompting input.
In the time that the described state that exceeds the time limit to remind is unlatching, described encryption apparatus obtains the prompting rule of the described BIOS cryptographic validity of storing in described FLASH, and described prompting rule comprises reminder time.
