Analog Devices / Maxim Integrated DS28C36 Deep Cover® 保安驗證器

Maxim DS28C36 Deep Cover®安全驗證器提供一組源自整合式不對稱(ECC-P256)和不對稱(SHA-256)安全功能的核心加密工具。 除了硬件執行的加密引擎提供的安全服務以外，該裝置還整合了一個FIPS/NIST真隨機數生成器(RNG)。 該裝置還整合了8Kb的安全EEPROM、一個僅遞減計數器、雙引腳可配置GPIO，以及一個64位元ROM識別編號(ROM ID)。 ECC公共/私有密鑰功能透過NIST定義的P-256曲線運作，並包括FIPS 186相容的ECDSA簽名生成和驗證，以支持雙向不對稱密鑰驗證模式。 SHA-256密鑰功能相容於FIPS 180，可靈活搭配ECDSA運行或獨立用於多項HMAC功能。

The Analog Devices DS28C36 Deep Cover Secure Authenticator is offered in a TDFN-6 package with an exposed pad for superior thermal performance.
