应用层不是通过普通的Read/Write命令读/写RPMB上的数据,而是通过SECURITY PROTOCOL OUT/IN命令来访问RPMB的。 UFS主机在访问设备RPMB时,是通过下面消息交互完成的。 每条消息包含一条或者若干条消息数据帧。消息数据帧大小是512字节,具体如下: 从中,我们看到: 认证密钥(Key)是32字节; 1使用SHA-256
UFS主机在访问设备RPMB时,是通过下面消息交互完成的。 每条消息包含一条或者若干条消息数据帧。消息数据帧大小是512字节,具体如下: 从中,我们看到: 认证密钥(Key)是32字节; 1使用SHA-256计算MAC,就是任意长度的数据,产生的MAC值总是256比特,即MAC大小为32字节。 逻辑块数据大小为256字节。 写计数(Write Counter)...
RPMB单元描述符 此描述符包含有关设备电源功能和电源状态的信息。RPMB单元描述符的地址设置为:DESCRIPTOR IDN = 02h,INDEX = C4h,SELECTOR = 00h;电源参数描述符的地址设置为:DESCRIPTOR IDN = 08h,INDEX = 00h,SELECTOR = 00h。 1.1 标志(flags) 标志一般是 TRUE 或 FALSE 的单个布尔值,可以清除或重置...
