Abstract
A mobile device obtains an encryption key pair, including a public key and a private key, and engages in a process, that uses the private key, for requesting a digital certificate from a Public Key Infrastructure (PKI) Certificate Authority. The mobile device receives a digital certificate signed by the PKI Certificate Authority, and obtains, via a biometric input unit device, biometric data related to an identity of a user of the device. The mobile device derives a password using the biometric data, and stores, and password protects using the derived password, the public key, the private key, and the digital certificate in a secure key store.
