Summary. In this chapter Data Matrix ECC200 for .NET , we"ve considered some aspects of smart card middleware on a variety of computer platforms. We"ve concentrated on the PC/SC architecture as it has been applied to both Windows platforms as well as a variety of other general computer platforms.

This has provided a means of making applications independent of specific smart card readers and, to a large extent, provided for the prospect of obtaining smart cards (for a particular application) from a variety of vendors. We"ve looked at the use of the PC/SC specifications to build smart card stacks on many PC configurations besides Windows. In addition, we"ve looked at the use of smart cards to support cryptographic services in the context of a PC/SC-based smart card stack.

Introduction A subscriber id VS .NET gs1 datamatrix barcode entification module is a smart card that is used in a communication device. It is usually known by its acronym, SIM.

There were approximately 600 million SIMs in GSM and 3G mobile phones and 70 million SIMs in DTH TV set-top boxes as of the end of 2001. SIM smart cards are being added to TDMA and CDMA mobile phones and to PDAs such as the Palm Pilot and the Handspring Visor ; their use as general-purpose network identity tokens is being actively explored. SIMs are by far the leading application of smart cards and the big-ticket items from most smart card manufacturers.

The SIM has two primary purposes. The first is to enable access to a particular communication network by the device (telephone handset) in which it, the SIM, has been inserted. The second is to undeniably and contractually associate the subsequent use of that network with a payment account.

The first purpose is authorization and the second purpose is authentication, non-repudiation and accounting. The SIM often provides other services such as the creation of session keys for encryption and the storage of personal information such as telephone numbers. Historically, the SIM was owned, issued, and managed by the operator of the network to which it authorized access.

In particular, it was not owned by the person paying the bills for network use or by the person using the communication device. In this regard, SIM is like a bank card that is owned by the bank. But also like a bank card, as the SIM evolves to become an application platform that can contain multiple accounts and provide access to multiple (and possibly competing) networks, this is changing.

In this new model, what used to be the purpose-built SIM smart card is a bag of bits on a multiapplication and multi-issuer smart card. Not surprisingly, this has set off a scramble for who is the card"s super user and has root privileges. Telecom operators are convinced that you should put your banking applications on their SIM cards.

Banks are of the view that you should put your telecommunications applications on. their bank card s. About the only thing they see eye-to-eye on is that person paying the piper you doesn"t call the tune. The cardholder owned and operated "white card" is an anathema to both of them.

This too is slowly changing. Besides being a tamper-resistant place to store keys and perform cryptographic operations, the easy portability of the SIM card lets both the issuer and the subscriber move the SIM"s data, including payment account information from one communication device to another and even to use this payment data in non-network settings. There is no technical reason, for example, that the same keys that protect your bits on a 3G network couldn"t protect your bits on a WiFi network.

In fact, there are some European GSM network operators that are doing exactly this. Pop the SIM out of your Nokia 5190 GSM handset, pop it into your Nokia C110 WiFi card, and carry on. It"s all digital communications and it"s always you.

The portability story of the SIM is given lie somewhat by some cellular network operators who don"t want you to use another operator"s SIM in the handset that comes with the packages they sell. Handsets that only work with one operator"s SIM are called locked, or latched, phones because they will only work with (are locked to) SIMs from the network operator that sold you the handset. If you buy a phone from VoiceStream, for example, it will likely (as of this writing) only work with a SIM provided by VoiceStream.

The cost of the handsets in these packages is heavily subsidized by the operator selling the package and they understandably want to recoup this subsidy through your use of their network. Of course, you can buy unsubsidized handsets that are not locked and can be used with any operator"s SIM. Just don"t typically expect to buy one from an operator.

SIMs are becoming application platforms. This seems strange at first blush for a smart card that has such a highly focused purpose and has been so financially successful fulfilling this purpose. Why add applications with dubious business models and risk upsetting the authorization applecart .
