By Jan De Clercq On This Page Introduction The need for security and enhanced privacy is increasing as electronic forms of identification replace face-to-face and paper-based ones. The emergence of the global Internet and the expansion of the corporate network to include access by customers and suppliers from outside the firewall have accelerated the demand for solutions based on public key cryptography technology. A few examples of the kinds of services that public key cryptography technology enables are secure channel communications over a public network, digital signatures to ensure image integrity and confidentiality, authentication of a client to a server (and vice versa), and the use of smart cards for strong authentication. The Microsoft Windows operating system platform is smart card–enabled and is the best and most cost-effective computing platform for developing and deploying smart card solutions. What Is a Smart Card? Multi-ISO High Frequency Smart Card Reader with or without Keyboard Emulation. You won't get stuck in a rut with this scalable, upgradeable. Enabling the reader to read the unique identifier (UID) and chip serial number (CSN) of any. A smart card is a small, tamperproof computer. The smart card itself contains a CPU and some non-volatile storage. In most cards, some of the storage is tamperproof while the rest is accessible to any application that can talk to the card. This capability makes it possible for the card to keep some secrets, such as the private keys associated with any certificates it holds. The card itself actually performs its own cryptographic operations. Although smart cards are often compared to hard drives, they’re “secured drives with a brain”—they store and process information. Smart cards are storage devices with the core mechanics to facilitate communication with a reader or coupler. They have file-system configurations and the ability to be partitioned into public and private spaces that can be made available or locked. They also have segregated areas for protected information, such as certificates, e-purses, and entire operating systems. In addition to traditional data storage states, such as read-only and read/write, some vendors are working with sub states best described as “add only” and “update only.” Smart cards currently come in two forms, contact and contactless. • Contact cards require a reader to facilitate the bidirectional connection. The card must be inserted into a device that touches the contact points on the card, which facilitate communication with the card’s chip. Contact cards come in 3-volt and 5-volt models, as do current desktop CPUs. Contact card readers are commonly built into company or vendor-owned buildings and assets, cellular phones, handheld devices, stand-alone devices that connect to a computer desktop’s serial or Universal Serial Bus (USB) port, laptop card slots, and keyboards. • Contactless cards use proximity couplers to get information to and from the card’s chip. An antenna is wound around the circumference of the card and activated when the card is radiated in a specific distance from the coupler.
