GPU-BASED FAST PASSWORD RECOVERY SYSTEM AND METHOD FOR MS-OFFICE |
摘要 |
<p>PURPOSE: A GPU-based fast password recovery system and a method for an MS-Office are provided to rapidly restore an encryption password inputted by a user from a file encoded in an Office 97/2000 compatibility check algorithm. CONSTITUTION: A data extraction unit(410) extracts a DOCID, a SALT and a HASHEDSALT value from an encoded MS-Office, and a password generator(420) receives or generates passwords. A main unit(400) stores the extracted values at a parameter memory of a graphic processor as well as the passwords at the global memory of the graphic processor. The main unit outputs the stored passwords by using a password recovery algorithm based on the values stored at the parameter memory for the passwords stored at the global memory.</p> |
