DS28E15：内置1-Wire SHA-256和512位用户EEPROM的DeepCover安全认证方案
利用强大的加密认证技术和先进的物理保护措施有效保护您的研发投入
DeepCover®嵌入式安全方案通过多层高级物理保护为系统提供最安全的密钥存储，有效保护敏感数据。 DeepCover安全认证器件(DS28E15)集成了基于FIPS 180-3安全散列算法(SHA-256)的质询-响应安全认证功能和512位用户可编程EPROM。附加存储器为SHA-256操作储存密钥。每款器件带有唯一的64位ROM注册码(ROM ID)，由工厂刻入芯片。DS28E15所产生的SHA-256信息认证码(MAC)通过计算用户存储器数据、SHA-256密钥、主控制器随机质询码以及64位ROM ID生成。提供安全的低成本、工厂可编程服务，预装器件数据(包括SHA-256密钥)。DS28E15利用Maxim单触点1-Wire®总线通信。
