Product Details
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.Our Secure Drug Delivery video shows how Maxim security products can be used to authenticate remote drug delivery.
