DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.
The DeepCover Secure Authenticator (DS28E15) combines secure challenge and response authentication functionality based on the FIPS180-3 specified Secure Hash Algorithm (SHA-256) with 512 bits of user-programmable EEPROM. Additional secure memory holds a secret/key for SHA-256 operations. Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E15 generates the SHA-256 message authentication code (MAC) computed from data in the user memory, the SHA-256 secret, a host controller random challenge, and the 64-bit ROM ID. A secure and low-cost factory-programming service is available to preprogram device data including the SHA-256 secret. The DS28E15 communicates over Maxim's single-contact 1-Wire® bus.

Product Detail

The DS28E15 evaluation system (EV system) provides the hardware and software necessary to evaluate and program the DS28E15 DeepCover® Secure Authenticator. EV system operation requires a host PC for user-friendly evaluation.
This evaluation system includes a DS9400 USB-to-I2C PC adapter, a DS2465 EV board, a DS9120Q+ evaluation socket board for a TDFN DS28E15, and five DS28E15 sample devices in a TDFN package. The EV software runs on Windows® 8, Windows 7, Windows Vista®, and Windows XP® operating systems. Detailed instructions for downloading and installing software, as well as general EV system operation are included in the EV system data sheet; software and documentation are available at the link above.
Note: The DS2465 EV board and DS9400# subcomponents are not available for direct sale outside of evaluation systems. A data sheet specific to DS9400# is not available.
