Analog Devices / Maxim Integrated DS28C36 Deep Cover® 安全认证平台
Maxim DS28C36 Deep Cover® 安全认证平台提供从集成对称 (ECC-P256) 和不对称 (SHA-256) 安全功能中演化而来的一整套核心加密工具。 除了硬件实施加密引擎提供的安全服务之外，该器件还集成有 FIPS/NIST 真随机数生成器 (RNG)。 该器件还集成有 8Kb 安全 EEPROM、一个只减计数器、两个可配置 GPIO 引脚和一个独特的 64 位 ROM 识别号（ROM ID）。 ECC 公开/私有密钥能力可在 NIST 定义的 P-256 曲线下工作，包括 FIPS 186 兼容 ECDSA 签名生成和认证，以支持双向不对称密钥认证模型。 SHA-256 密钥能力符合 FIPS 180 标准，既可灵活地配合ECDSA 操作使用，也可独立用于众多 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.
