Smart cards created using the Java Card platform have Java applets stored on them. The applets can be added to or changed after the card is issued. There are two basic types of smart cards. The memory smart card is the familiar removable memory device; it usually features read and write capabilities and perhaps security features. The more complex version, the processor smart card, is a very small and extremely portable computing device that could be carried in your wallet. Java-based smart cards belong to the latter category. They store data on an integrated microprocessor chip. Applets are loaded into the memory of the microprocessor and run by the Java Virtual Machine. Similarly to MULTOS, another smart card development technology, Java Card enables multiple application programs to be installed and coexist independently. Individual applets are protected by a firewall to preserve their integrity and prevent tampering. Applications can be updated dynamically. In the United States, the Department of Defense, Visa, and American Express are among the organizations creating Java Card-based applications.

THE CHALLENGE: Karen, the new information security manager for a utility company, has a gut feeling that despite the lack of any previously known security breaches, her new company's sensitive customer information is vulnerable. The systems administrator has assured Karen that the data is safe because it is compressed with a private algorithm. Karen thinks he may be confusing a coding algorithm with an encryption algorithm. Should Karen speak up? >>Take the challenge http://searchsecurity.discussions.techtarget.com/WebX?[EMAIL PROTECTED]@.1dcf9d94/65!viewtype=threadDate&skip=&expand= ______________________ QUIZ #10 | iSeries(AS/400) commands Take our latest quiz and see if you can logically figure out which commands to use for specific tasks on IBM's iSeries (AS/400). Even if you've never worked with the iSeries, we bet you can figure out how to run one! iSeries (AS/400) commands http://search400.techtarget.com/sDefinition/0,,sid3_gci841205,00.html ______________________________ RECENT ADDITIONS AND UPDATES [1] logical negation symbol http://whatis.techtarget.com/definition/0,,sid9_gci843775,00.html [2] transcription error http://searchdatabase.techtarget.com/sDefinition/0,,sid13_gci843776,00.html [3] polarization http://whatis.techtarget.com/definition/0,,sid9_gci843762,00.html [4] NSFNET http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci843763,00.html [5] HDCD http://whatis.techtarget.com/definition/0,,sid9_gci843768,00.html ____________________________________________________________________ ::::::::::::::::::: WHATIS.COM CONTACTS ::::::::::::::::::: LOWELL THING, Site Editor ([EMAIL PROTECTED]) ____________________________________________________________________ MARGARET ROUSE, Assistant Editor ([EMAIL PROTECTED]) ___________________________________________________________________ :::::::::::::::::::: ABOUT THIS NEWSLETTER ::::::::::::::::::::: Created by TechTarget (http://www.techtarget.com) TechTarget - The Most Targeted IT Media Copyright 2002, All Rights Reserved.
