Application of Smart Card in PC network environment

Ever since smart card was invented, it has been widely applied in many areas including access control in network. However, it has more potential and plays a very important role in online security system.

1. Local access control

In local server, there is a smart card reader, when an user inserts his personal card into the reader with his personal PIN, he can access the system immediately. The smart card is a key to users access. It authorizes user’s accessiblity with the smart card reader. In the smart card, user’s personal information and accessiblity is stored and this information controls up to which level he can go in the system.

2. Long distance access

When user is verified by local server, it will send a connecting request to long distance server. To avoid password to be lost in the process of transmission, “one time password (OTP)” is applied. In interactive working situation, the host will use question-answer protocol to verify user’s smart card. The host security model will generate a random R and send it to local server to the smart card. Smart card will input this R with secret parameter K. This will be calculated by card’s processor and generate a result – X and  the result will be directed back to host. The host will do a reverse calculation to get the R. If R equals to R, the user will be able to access the system.
