Abstract

A dynamic token having a log function and a working method therefor. After the dynamic token determines that a key interrupt flag is set, a keyboard is scanned to obtain a first key value, and a currently pressed key is judged according to the first key value; if the currently pressed key is a first key, a dynamic password and a log corresponding to the dynamic password are generated; the dynamic password is stored in a display data buffer area, and the log is stored in a log storage area; key interrupt is enabled; and if the currently pressed key is a second key or a combination of a third key and a fourth key, the log is read from the log storage area, and the read log is stored in the display data buffer area. According to the present invention, by recording information related to the completed identity authentication by means of a dynamic token, a user can recheck whether the completed identity authentication is identity authentication completed by himself/herself, thereby improving the security of an identity authentication mechanism and the dynamic token which uses a dynamic password.

Claims20

Dependent claims

A working method for a dynamic token with log function, characterized in that said working method comprises the following steps:

S1) powering up, by the dynamic token, executing initializing operation, initializing function of general interruption and key waking up function;
S2) determining, by the dynamic token, whether a set interruption flag exists, if yes, executing Step S3;
otherwise, keeping on executing Step S2;
S3) determining, by the dynamic token, the set interruption flag, if the set interruption flag is timer interruption flag, executing Step S4;
if the set interruption flag is key interruption flag, executing Step S5;
S4) resetting, by the dynamic token, the timer interruption flag and going back to Step S2;
S5) shutting down, by the dynamic token, the key interruption, scanning a keyboard and obtaining a first key value;
S6) determining, by the dynamic token, a press key which is currently pressed down according to the first key value, if the press key which is currently pressed down is a first press key, executing Step S7;
if the press key which is currently pressed down is a second press key or combination of a third press key and a fourth press key, executing Step S8;
S7) generating, by the dynamic token, a dynamic password and a log corresponding to the dynamic password, storing the dynamic password in a display data buffer, storing the log in a log storage area, initializing the key interruption and going back to Step S2;
and
S8) reading, by the dynamic token, the log from the log storage area, storing the read log into the display data buffer, activating the key interruption and going back to Step S2.

9 more elements

A dynamic token with log function, wherein said dynamic token comprises:

an initializing module configured to, after being powered up, execute initializing operation, activating general interruption and press key waking function;
a first determining module configured to determine whether a set interruption flag exists;
a second determining module configured to, after the first determining module determines that the set interruption flag exists, determine the set interruption flag;
a resetting module configured to, after the second determining module determines that the set interruption flag is timer interruption flag, reset the timer interruption flag and trigger the first determining module to determine whether the set interruption flag exists;
a first obtaining module configured to, after the second determining module determines that the set interruption flag is key interruption flag, shut down the key interruption, scan a keyboard and obtain a first key value;
a third determining module configured to determine a press key which is currently pressed down according to the first key value obtained by the first obtaining module;
a first processing module configured to, after the third determining module determines that the press key which is currently pressed down is a first press key, generate a dynamic password and a log corresponding to the dynamic password, store the dynamic password in a display data buffer, store the log in a log storage area, initialize the key interruption and trigger the first determining module to determine whether the set interruption flag exists;
and
a second processing module configure to, when the third determining module determines that the press key which is currently pressed down is the second press key or combination of a third press key and a fourth press key, read a log from the log storage area, store the read log in the display data buffer, activate the key interruption and trigger the first determining module to determine whether a set interruption flag exists.
