发明名称 Method and system for protecting master secrets using smart key devices
摘要 A data processing system accepts a removable hardware device, which becomes electrically engaged with a system unit within the data processing system, after which the removable hardware device and the hardware security unit mutually authenticate themselves. The removable hardware device stores a private key of a first asymmetric cryptographic key pair and a public key of a second asymmetric cryptographic key pair that is associated with the hardware security unit, and the hardware security unit stores a private key of the second asymmetric cryptographic key pair and a public key of the first asymmetric cryptographic key pair that is associated with the removable hardware device. In response to successfully performing the mutual authentication operation between the removable hardware device and the hardware security unit, the system unit is enabled to invoke cryptographic functions on the hardware security unit while the removable hardware device remains electrically engaged with the system unit.
