KEROSTM 规格
介绍
KEROS会内置先进的加密化功能的AES256,提供2K Bytes的EEPROM用户区域的高性能保安存储装置.
EEPROM分为8个用户区域, 此8个用户EEPROM区域里保存单/双数的数据时，
个个区域可以应用不同的加密功能。组成区域里为了用户读写EEPROM区域密码和已包含使用在
ChipsBrain Global加密IC的AES256秘密KEY.
通过动态，对称，相互认证，数据加密解密,提供把使用的系统内重要并敏感的信息，
能安全的保存EEPROM区域。这种保护电路使外部攻击中也可以安全的储存信息
KEROS在host-client类型系统中，提供高安全性,低成本,简单体现.包含在KEROS的
AES256加密算法是动态, 跟host-client间提供对称互相认证.
不仅还会host-client间另行加密传输所有数据的密码.
