完整性受保护的安全存储设备的实施

Implementation of an integrity-protected secure storage

Abstract

An internal but not integrated security token is provided for a device which comprises a first integrated circuitry comprising a secure processor. The security token is provided by a second integrated circuitry separate from the first circuitry. The second integrated circuitry comprises a secure non-volatile storage. The secure processor communicates information to the second circuitry in a secure manner for the secure information to be securely stored in the secure non-volatile storage, and the second integrated circuitry communicates information stored in its secure non-volatile storage to the secure processor in a secure manner. Communications is secured by means of cryptography. The first integrated circuitry and the second integrated circuitry are internal parts of the device. An initialization method for distributing a secure key to be shared between the circuitries and to be used in cryptography is also disclosed.
为一种包括第一集成电路的设备提供内部的但不是集成的安全令牌,该第一集成电路包括安全处理器。通过与第一电路相分离的第二集成电路来提供安全令牌。第二集成电路包括安全的非易失性存储设备。安全处理器以安全的方式将信息传送到第二电路以便安全信息安全地存储于安全的非易失性存储设备中,而第二集成电路以安全的方式将它的安全非易失性存储设备中存储的信息传送到安全处理器。借助密码术来保证通信安全。第一集成电路和第二集成电路是设备的内部部分。也公开了一种用于分发将要在电路之间共享的并且将要在密码术中使用的安全密钥的初始化方法。
