DS28E15P+ (MAXIM INTEGRATED PRODUCTS)

The DS28E15P+ is a DeepCover secure authenticator with 1-wire SHA-256 and 512bit user EEPROM in 6 pin TSOC package. DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide most secure key storage possible. The DS28E15 combines secure challenge and response authentication functionality based on FIPS180-3 specified secure hash algorithm (SHA-256) with 512bits of user programmable EEPROM. Additional secure memory holds a secret/key for SHA-256 operations. Each device has its own unique 64bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E15 generates SHA-256 message authentication code (MAC) computed from data in user memory, SHA-256 secret, host controller random challenge and 64bit ROM ID. A secure and low cost factory programming service is available to pre-program device data including SHA-256 secret. It is used in authentication of consumables, secure feature control.
