As with all smartcard types, the selection of a card operating system depends on the application that the card is intended for. The other defining difference lies in the encryption capabilities of the operating system and the chip. The types of encryption are&nbsp;<i>Symmetric Key<\/i>&nbsp;and&nbsp;<i>Asymmetric Key (Public Key)<\/i>.<\/p>\n<p>The chip selection for these functions is vast and supported by many semiconductor manufacturers. What separates a smart card chip from other microcontrollers is often referred to as trusted silicon. The device itself is designed to securely store data withstanding outside electrical tampering or hacking. These additional security features include a long list of mechanisms such as no test points, special protection metal masks and irregular layouts of the silicon gate structures. The trusted silicon semiconductor vendor list below is current for 2010:<\/p>\n<ul class=\"bodytext\">\n<li><a href=\"http:\/\/www.atmel.com\/\" target=\"blank\" rel=\"noopener\">Atmel<\/a><\/li>\n<li><a href=\"http:\/\/www.emsystem.com\/\" target=\"blank\" rel=\"noopener\">EM Systems<\/a><\/li>\n<li><a href=\"http:\/\/www.infineon.com\/cms\/en\/product\/applications\/chip-card-and-security\/index.html\" target=\"blank\" rel=\"noopener\">Infineon<\/a><\/li>\n<li><a href=\"http:\/\/www.microchip.com\/\" target=\"blank\" rel=\"noopener\">Microchip<\/a><\/li>\n<li><a href=\"http:\/\/www.nxp.com\/\" target=\"blank\" rel=\"noopener\">NXP<\/a><\/li>\n<li><a href=\"http:\/\/am.renesas.com\/\" target=\"blank\" rel=\"noopener\">Renesas Electronics<\/a><\/li>\n<li><a href=\"http:\/\/www.samsung.com\/global\/business\/semiconductor\/products\/microcontrollers\/Products_Microcontrollers.html\" target=\"blank\" rel=\"noopener\">Samsung<\/a><\/li>\n<li><a href=\"http:\/\/americas.sharpmicro.com\/Page.aspx\/americas\/en\/4b75c4dc-92d0-44cd-a08c-86eafbfa7b43\" target=\"blank\" rel=\"noopener\">Sharp<\/a><\/li>\n<li><a href=\"http:\/\/www.sony.net\/Products\/SC-HP\/index.html\" target=\"blank\" rel=\"noopener\">Sony<\/a><\/li>\n<li><a href=\"http:\/\/www.st.com\/stonline\/domains\/applications\/security\/index.htm\" target=\"blank\" rel=\"noopener\">ST Microelectronics<\/a><\/li>\n<\/ul>\n<p>Many of the features that users have come to expect, such as specific encryption algorithms, have been incorporated into the hardware and software libraries of the chip architectures. This can often result in a card manufacturer not future-proofing their design by having their card operating systems only ported to a specific device. Care should be taken in choosing the card vendor that can support your project over time as card operating system-only vendors come in and out of the market. The tools and middleware that support card operating systems are as important as the chip itself. The tools to implement your project should be easy to use and give you the power to deploy your project rapidly.<\/p>\n<p>Please see the&nbsp;<a title=\"smart card security\" href=\"https:\/\/www.smartcardbasics.com\/smart-card-security.html\">security section<\/a>&nbsp;on this website for more information regarding PKI.<\/p>\n<div class=\"indent-1\">\n<h6>Fixed File Structure Card Operating System<\/h6>\n<p>This type treats the card as a secure computing and storage device. Files and permissions are set in advance by the issuer. These specific parameters are ideal and economical for a fixed type of card structure and functions that will not change in the near future. Many secure stored value and healthcare applications are utilizing this type of card. An example of this kind of card is a low-cost employee multi-function badge or credential. Contrary to some biased articles, these style cards can be used very effectively with a stored biometric component and reader. Globally, these types of microprocessor cards are the most common.<\/p>\n<h6>Dynamic Application Card Operating System<\/h6>\n<p>This type of operating system, which includes the JavaCard&reg; and proprietary MULTOS card varieties, enables developers to build, test, and deploy different on card applications securely. Because the card operating systems and applications are more separate, updates can be made. An example card is a SIM card for mobile GSM where updates and security are downloaded to the phone and dynamically changed. This type of card deployment assumes that the applications in the field will change in a very short time frame, thus necessitating the need for dynamic expansion of the card as a computing platform. The costs to change applications in the field are high, due to the ecosystem requirements of security for key exchange with each credential. This is a variable that should be scrutinized carefully in the card system design phase.<\/p>\n<\/div>\n<div id=\"site-navigation\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>The two primary types of smart card operating systems are (1)&nbsp;fixed file structure&nbsp;and (2)&nbsp;dynamic application system.
