Using SuperPro XM keys
Every SuperPro XM key contains 512 bytes of memory, organized as 256 cells (words) of 16 bits each. Cells are addressed as locations 00 to FF hex. Cells 00 through 07 are restricted cells that contain fixed, preprogrammed system information. Cells F0 through FF are also reserved for use by SafeNet.
When you program the key, you are actually assigning attributes to the cells. These attributes describe how the words contained in the cells are used to protect your application. There are three cell attributes: cell type, access code and cell value. Each of these attributes are explained in detail in Chapter - 2 of Sentinel SuperPro Developer’s Guide.
Why use SuperPro XM?
SuperPro XM keys provide an additional algorithm engine that uses industry standard AES (Advanced Encryption Standard) encryption to generate unique query responses. A proprietary algorithm is used to generate a 128-bit AES key that is derived from the algorithm descriptor and other developer specific information within the key. This results in an extremely secure query/response mechanism. In addition to the AES based algorithm engine, SuperPro XM keys provide the following:
256 memory cells which give you the room to protect more applications.
Protection against brute force attacks of the Write and Overwrite Passwords.
我试过根据SproDump v 0.2 Spath的源代码修改0－3F到0－FF但DUMP数据不成功，好象对这种狗的底层驱动不再是Sentinel.sys而是SNTNLUSB.SYS（USB的）。还有对于Query如何处理？SproDump没有对Query处理的代码。请帮忙看看。谢谢！
