Abstract

A computerized system offers a uniform platform for conducting electronic transactions in multiple different environments. The system includes a portable, multi-purpose, integrated circuit (IC) card and complimentary computer software which enables access and management of resources maintained on the IC card. The software runs on a user's personal computer, empowering the user to initialize the IC card, configure the card with the resources that the user wants to maintain on the card, and to manage those resources. The software enables the user to generate private/public key pairs and establish or change passcodes for access to the card resources. The IC card itself provides the electronic vehicle for securely transporting the user's private keys and certificates without exposing them in plaintext form. The IC card is designed with enough processing capabilities to perform rudimentary cryptographic functions so that the private keys may be employed for signing or encryption without ever being released from the card.
