Sentinel Hardware Key (SHK) by SafeNet Inc. is the second generation key. It was created as a replacement for old Sentinel SuperPro, the first generation key with compromised secret algorithms.
Made in China. Plastic corpse. Dimensions are 55x16x8 mm. Gray “SafeNet Sentinel” sticker may be replaced with a self-designed one. Free space for extra vendor information on back side.

Compare to the SuperPro model SHK got

• New key design you may see on the image above.
• Internal memory size up to 4Kb.
• Simple file system memory structure.
• Real Time Clock (RTC) as optional feature.
• Standard ECDH algorithm for common key generation.
• Communication channel protected with AES.
• Standard AES algorithm for Encrypt/Decrypt operations.
• Standard ECDSA algorithm for Sign/Verify operations.
• New Application Programming Interface (API).
• Java-based SDK tools for developers.
• New envelope for automatic programs protection

Features are very similar to WIBU CodeMeter, but implementation absolutely different. Anyway, both keys are weak to record-and-playback attacks because of predictable behavior.

SHK dongle memory backup tools (SHK dongle dumper) has been developed by our specialists. It is absolutely free. So, do not waste the time and backup your key now. Follow the instruction to backup public key data or send a free-form request to get the instructions for backup protected memory data. At the current moment no known ways to backup secret data, so SHK emulators are version specific. Also called “table-based” or “table-driven”. It is typical for the second generation keys.
