The microprocessor card can add, delete, and otherwise manipulate information on the card, while a memory-chip card for example, pre-paid phone cards can only undertake a pre-defined operation. Smart cards, unlike magnetic stipe cards, can carry all necessary functions and information on the card, Therefore, they do not require access toremote databases at the time of the transection, This paper deals with what is a smart card, why smart cards are used, what are the different types of chip cards, multi application card systems, and their security This paper mainly concentrates on smart cards security. Lastly this paper discuss on applications and on future scope. Introduction Asmart card, a type of chip card is a plastic card embedded with a computer chip that stores and tansacts data between users, This data is associated with either value or information or both and is stored and processed within the card's chip, either a memory or microprocessor. The card data is transacted via reader that is part of a computing system. They provide tamper-proof storage of user and account identity. Smart cards also provide vital components of system security for the exchange of data throughout virtually any type of network. They protect against a full range of security threats, from careless storage of user passwords to sophisticated system hacks. Securing Information and Physical Assets In addition to information security, smart cards achieve grealr physical secunty of services and equipment, because the card rosticts access to allbut the authorized users E-mail and PCs are being locked- down wth smart cards.

Users can be authenticated and authorized to hhave access to specficinformation based on preset privileges. How the card data is read and written and 2. The type of chip implanted within the card and its capabilties, There is wide range of options to choose from when designing your system. Single fanation cards are offen the most cost-effective soluion, Choose the right type of smartcard fr your appication by valuabng cost versus functonalty and determine your required level of secutly. Al ofthese vaiables should be weighted agains the expected lifecycle ofthe card. On average th cards typically comprise ony 10 fo 15 percent ofthe total systom cost wth the infaeructro, issuance, traning and advertising making up tho athor 85 porcork. Thore are three prmary typos of memory cards: 1. Straight, 2. Protected, and 3. Stored Value. They should be regarded as floppy disks of varying sizes wthout tho lock mechanism. This is usually done through a password or system key. Segmented memory cards can be divided into logical sections for planned mmuli-functionaiity. These cards are not easily duplicated but can possibly be impersonated by hackers. They typically can be tracked by an on-card identifier. The memoy arayson these devices are setup as decrements or counters. A memory callis cleared each tme a telephone unit is used.

At the same time, the integration of smart cards into your system introduces its own security management issues, as people access card data far and wide in a variety of applications. What Is Security? SSocuily is basiealy the protection of omathing valuable to ensure that tis not stolen ast, or altered. Data is created, updated, exchanged and stored via networks. In ary network, diversiy abounds, certainly in tems of types of ala, but also types of users. For that reason, a system of secu fs essential to maintain computing and network funcions, keep sensitive data secret or simply maintain worker safely. Te frst simply deals. The second grapples wih issues of ncvicualfeadom, publ Concerns, legal standards-and how the need fr privacy interseets them. The eventual choice rests wth the system designer and issuer, The Elements Of Data Security Inimplementng a security system, al data networks deal wah the folowing main elements: Hardware, including servers, rodundart mass storage devices, communication channels and lines, hardware tokens smet cards and Temotly located devices e. Personne, to act as crginalorsandior users ofthe dats, professional personnel, clerical staff, administrative personnel, and computer staff The Mechanisms Of Data Security Working withthe abevo cloments, an ofacbve data security eystom works wit the folowing key mechanisms to answor: 1. Has My Data Arrived Intact? Osta integity This mechanism ensures tat dala was not lost or conupted when i was sen to you 2. Authentication This praves user of system identities 3. Non- Repuxiation 4. Confidontaliy - Ensuros only sondore and Fecoivors access tho data. Auctng and Logging Provides constant monitor and troubleshooting of secutly system function 7. Data Integr is achieved with electronic cryptography that assign a unique Henk to data ke a fingorpint. Any attomptto change tis dontty signals the change and tage any tampering Authentication This inspects, then confems, the proper identity of people Involved in a transaction of data or vale. In authenteation systoms, authonicaion is measured by assessing the mechanisms strength and how nay factors are used to confim the identity, Ina PKI sjslem a Digital Signature verifes data atts origination by Producing an ident that can be mutually vetted by all Patties involvedin the transaction. Similar in conceptto registered mail, the recpient of data re- hashes it ves the Digtal Signature, and compares the two to see that they match, Authorization and Delegation Authorization is the processes of allowing access to specific data within a system. Delegation is the utilization of a third party to manage and certify each of the users of your system. Plain tee is turned inte cipher tot via an algorithm, then decrypted backint plain txt using the same method. CCrypography is the method of converting data rom a human readable farm toa madd form, and then back torts orginal readaale frm, to make unauthorized access difcut. The process of converting encrypted data to unencrypted datas caled decryption Data Security Mechanisms and their Respective Algorithms Inorder to convertthe data, you need to have an toneryption algorithm and a koy. Tho algorithm has boon studied by erptographers for neary 20 years. During this ime, no methods have been published that descrivea way to break the algorthm, except for brte-force techniques. Triple-DES can be dane with two or wah three keys. Since the algorhm performs an encrypt: eerypt-oncrypt sequence, ths is sometimes called the EDE mode. This diagram shows Tnple. DES thiee-key mode used for encryption If ferent keys are used for encryption and decryption, the algorithm i called an asymmetre algorithm. Asymmetric algorthms are lypically stronger than a short key ength symmetric algorithm. There are two methods of Using cards for data system security hostbased and card-based, The safest systems employ both methodologies. Host-Based System Security A host-based system treats a card as a simple data carrier. Each time the card is re-written the host can write a reference to the keys, This way each transmission is different, But parts of the keys are in the clear for hackers to analyze, This securty can be increased by the use of smart memory cards that employ a password mechanism to prevent unauthorized reading of the data. Unfortunately the passwords can be sniffed in the clear, Access is then possible to the main memory. These methodologies ere often used when a network can batch up the data regularly and compare values and card usage and generate a problem card list Card-Based System Securty Thoso systoms aro typical microprocessor cae-basod, Acatd, or toten-based system treats a cad as an active compuing device. The inleracton between te host and the cad can be a sores of sops to dotrmine f the card is auhorized to be used inthe system. The process aso checks ifthe usor can be identified, authenticated and if the card wil present the appropriate credentials to Conducta transaction, The cad itself can also demand the same from fe host before proceeding wth a trensacton. The frst place an extemal hacker looks atis where they can inferegt the transmission of your data. Ina smart card- enhanced system this earts with he card The following sats of questions ao relovart to your analysis. Is the ala on th card tranemittodin the clea a is it cenerypted? Ifthe tranamissin is snifled, is each session socured wih a different key? Doos the data move from the reader tothe PC in the clear? Doos tho PC or ckart trenemitthe data in the clear? Isthore a mmecharism to upload and dovm load functioning code? How sezure i ths system? Does the OS provider have a good secu track record? Does the card manufacturer have procaine in place to secure your data? De thay Understand the libites? When the cardissubjaced to ferential Power altacks and Differential Thormal attacks does the 0S roveal any secrets? Wil he semiconductor uized meets scrutiny? This is changing over time, based on the sheer volume of transactions managed daily and the hassles that come with private key management. Private Key- based systems make good sense if your expected user base is less than , participants Public Key Systems are typically cost effective only in large volumes or where the value of data is so high that its worth the higher costs associated with this type of deployment. The Public Key encryption algorithms are only used for non-repudiation and to secure dala integrity. Public Key infrastructures as a rule employ every mechanism of data security in a nested and coordinated fashion to insure the highest level of security available today. Mark Manson.
