发明名称 Using a Portable Computing Device as a Smart Key Device
摘要 A first data processing system, which includes a first cryptographic device, is communicatively coupled with a second data processing system, which includes a second cryptographic device. The cryptographic devices then mutually authenticate themselves. The first cryptographic 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 second data processing system. The second cryptographic device 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 first data processing system. In response to successfully performing the mutual authentication operation between the two cryptographic systems, the first data processing system is enabled to invoke sensitive cryptographic functions on the first cryptographic device while the first data processing system remains communicatively coupled with the second data processing system.
