DS1964S-F5+ Allgemeine Beschreibung

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 i Button® (DS1964S) 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 user-programmable 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 DS1964S. Slave-to-host authentication is used by a host system to securely validate that an attached or embedded DS1964S is authentic. The DS1964S 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.
