Product Details
DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the industry's most secure key storage possible. The Deepcover Secure Authenticator (DS28EL15) combines crypto-strong bidirectional secure challenge-and-response authentication functionality with an implementation based on the FIPS 180-3-specified Secure Hash Algorithm (SHA-256). A 512-bit userprogrammable EEPROM array provides nonvolatile storage of application data. Additional protected memory holds a read-protected secret for SHA-256 operations and settings for memory protection control. Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. This unique ROM ID is used as a fundamental input parameter for cryptographic operations and also serves as an electronic serial number within the application. A bidirectional security model enables two-way authentication between a host system and slave-embedded DS28EL15. Slave-to-host authentication is used by a host system to securely validate that an attached or embedded DS28EL15 is authentic. Host-to-slave authentication is used to protect DS28EL15 user memory from being modified by a nonauthentic host. The DS28EL15 communicates over the single-contact 1-Wire® bus at overdrive speed. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.

Description
The DS9481R-200 is a USB-to-1-Wire® adapter for easy PC connectivity to 1-Wire devices. The adapter provides an RJ11 connector with the signals to communicate with all 1-Wire and iButton® devices that support a 1.8V data I/O level. Additionally, the adapter provides the support and signaling to program 1-Wire/iButton EEPROM devices. To provide a total hardware solution, the DS9481R-200 can readily be used with the family of DS9120 socket adapters to create a 1-Wire PC programmer for 1-Wire slave devices (contact factory for more information). The equivalent slave hardware solution for the iButton is the DS1402D-DR8.
