Due to the small display screen of the KEY, it is easy for users to ignore even if there is a prompt message
Therefore, when the KEY product cannot fully display the information to be signed on one screen, the user may directly confirm the information to be signed without fully reading the information to be signed
The hacker can initiate a malicious transaction process or modify the user's pending signature information after the user's signature information is displayed (for example, modify the user's account number and user name to be remitted). If the user does not notice that the content of the pending signature information has been modified, press the Press the confirm button and sign the information to be signed, which is likely to cause losses to the user

The invention discloses a method and a device for assuring to-be-signed information to be completely consulted. The method includes acquiring the number of characters of the to-be-signed information required to be displayed when a to-be-signed information displaying instruction is received; computing the number of required-to-be-displayed total pages of the to-be-signed information when the number of the characters of the to-be-signed information is larger than the number of characters which can be displayed on one page of a display screen of a KEY product; modifying confirmed signing operation pointed by a confirming key of the KEY product into unconfirmed signing operation, displaying the to-be-displayed information page by page and identifying the number of pages of the to-be-signed information currently displayed on the display screen; restoring the confirmed signing operation pointed by the confirming key of the KEY product when the number of pages of the to-be-signed information currently displayed on the display screen is equal to the number of the total pages of the to-be-signed information. The method and the device have the advantage that signing operation can be carried out only after the to-be-signed information is assuredly completely consulted.
Description
technical field [0001] The present invention relates to the field of information security, in particular to a method and device for ensuring that information to be signed is completely checked. Background technique [0002] During the use of the existing KEY product with a display screen, if there is a lot of information to be displayed and the KEY cannot fully display it on one screen, the KEY will display the information to be signed while the information to be signed has not been displayed. For the prompt information that is completely displayed, for example, an arrow is displayed at the inner corner of the display screen, or a page-turning prompt information such as "current page / total number of pages" is displayed. Due to the small display screen of the KEY, it is easy for users to ignore the prompt information even if there is one. Therefore, when the KEY product cannot fully display the information to be signed on one screen, the user may directly confirm the informa...
