ABSTRACT


Network security is a technology used to make its resources available to only authenticated people. There are varieties of techniques available on in this paper. We use Smart Card as an authentication device to have access to the resources.


Smart card is a credit card sized device having some IC’s (integrated circuits) within it. We have a crypto controller within it which is used to encrypt the users data namely: password, identity details etc. By this smart card the user will be able to access the computer resources by inserting the card in the smart card reader which is attached to the computer network. Once the card is inserted there is a query by the system which is answered by the user. If this tallies with that which had been registered and have been stored in the memory of smart card, then access is given to the user.


Smart card has variety of applications. The banks are planning in India to make use of smart cards in the place of magnetic strip cards used for credit and debit cards. These have an edge over the former in its inability to clone as the data is in the encoded form and the bus that is inside the smart card is not available for hacker to hack it. Moreover, smart cards are cheaper when are mass produced. There is a rough estimate of this cost, presently to be about $1 which may be much lower than the magnetic strip cards used. The government is also interested in making use of the same smart card for variety of other authentications like ID, bank transactions, income tax etc. Thus many applications can be built within a same smart card with no extra cost. Thus today it is the best authentication tool for network security.
