Function test method and device for RPMB in eMMC and computer equipment

The invention discloses a function test method and device for an RPMB in an eMMC and computer equipment, and belongs to the technical field of storage. In the method, a host can test one or more of anauthentication key writing function, a write counter function, an authentication data writing function, an authentication data reading function and an error processing function of the RPMB to obtaina function test result of the RPMB. In this way, the RPMB can be subjected to the function test which is rigorous and high in test coverage rate, and therefore the reliability of the RPMB and the capacity of the RPMB for preventing illegal tampering can be guaranteed. 本申请公开了一种eMMC中RPMB的功能测试方法、装置和计算机设备，属于存储技术领域。在该方法中，主机可以对RPMB的认证密钥写入功能、写计数器功能、认证数据写入功能、认证数据读取功能、错误处理功能中的一个或多个功能进行测试，以得到RPMB的功能测试结果。如此，可以对RPMB进行较为严谨且测试覆盖率较高的功能测试，从而可以保证RPMB的可靠性和其防止非法篡改的能力。
