At the, experts from Infineon, Wave Systems, HP, Wave Systems and Asguard Networks addressed a number of trending security issues and the role of trust in helping solve them. John Fitzgerald of Wave Systems addressed a commonly asked question for TCG: how to use the TPM. In this case, the TPM acts as a virtual smart card.
Why use the TPM for this application? Fitzgerald notes that passwords are easy to break and complex to manage, as well as expensive.
Poor passwords are a leading factor for breaches. Multi-factor authentication is stronger, but there are many choices and expensive and complex to manage as well. In fact, costs can be up to $150 per user, according to Gartner.
Digimon xros wars english rom. In this article, I will not speak about smart card OS emulation (perhaps it will be covered in the future.), but about a driver for a virtual smart card reader. To fully emulate the behavior of Windows Smart Card Resource Manager, you must implement lots of functions.
The TPM is included in enterprise PCs and can be turned into an inexpensive and more easily managed smart card. It’s tied to the platform and can’t be lost.
Its hardware root of trust offers strong authentication and allows only known users and known devices to access enterprise systems and data. TPMs in systems with Windows 7, 8 and 8.1 can be used as virtual smart cards.

Member 13303675 9-Aug-18 5:53 9-Aug-18 5:53 Hi Fabio, I am trying to port your driver to Windows 10, according the lines of the WDK10 UmdfSkeleton driver sample (which you used in a previous WDK Version). This resulted in a driver which installs without any complaint and hence seems fully functional in the device manager. It is accessible via TCP and pipe. However winscard ignores the Driver, i.e., it does not appear in the SCardListReaders() output. Have you ever experienced similar behavior during your driver development?
Or do you know of any fully functional Win10 port of your driver? Member 13365580 12-Mar-18 3:53 12-Mar-18 3:53 Hi Fabio, I'm trying to write a virtual smart card client to communicate with your driver via named pipes, however, I've ran into a few issues. From looking at your code (PipeReader.cpp), it seems necessary to create two pipes using CreateFile, and pipes should have PIPE_NAME and PIPE_EVENT_NAME, as defined in BixVReader.ini in%systemroot%. This works out find, and I manage to create/connect to the driver's named pipes. First, I tried reading from the data pipe, and this just blocks - i.e.
I'm not getting any check ATR requests. I'm using blocking pipes (so no OVERLAPPED) from C++ (msvc17). Then, I figured I should first send a command (1 - card inserted) to the event pipe, and this usually works (sometimes blocks as well - seems somewhat non-deterministic), however, it doesn't seem to be parsed correctly. For simplicity's sake, I tried sending command 0, which should either output 'Powered to zero' and 'Card removed' (if waitRemoveIpr is not empty). However, I only get: L ' [BixVReader]Pipe data What is the correct flow for emulating a smart card via named pipes, i.e.
How do I initiate the driver to ask for ATR, APDUs etc? Also, do I need to use asynchronous I/O (OVERLAPPED), or is blocking/synchronous OK)? Hi, please refer to the article  to have details about the implementation. The implementation provided is written in C#, not C++, but you should get an idea. Look at the file DriverCom PipeCom.cs. Pipes are opened as asynchronous, but.NET makes using them really simple. The message flow starts from the virtual smart card client.
As you correctly figured out, you have to send a notification that a (virtual) card is inserted in the reader through the event pipe. Then the driver, if there's an application waiting for a card, asks the ATR on the data pipe. Best regards, Fabio. That is excact my problem. I am using ia64, instead of x64. Thanks for your answer.
Now the configuration is success. But i found new problem, the device status said This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) How I can fix this?
I have another question too. If I want to make this to be tcp/ip type, am I just need to add this text below to BixVReader.ini? [Driver] NumReaders= 1 [Reader0] RPC_TYPE=tcp/ip VENDOR_NAME=VirtualCard VENDOR_IFD_TYPE=BixReader DECIVE_UNIT= 0 TCP_PORT= 6666 TCP_EVENT_PORT= 6667 Thanks a lot. Really appreciate your work. Member 8999743 25-Jun-17 1:51 25-Jun-17 1:51 In BixVReader for card remove/insert detection two variables are used (Reader.h): CComPtr waitRemoveIpr; CComPtr waitInsertIpr; When a smart card is absent `waitInsertIpr` will hold a pending `IWDFIoRequest` which will be completed when a smart card gets inserted.
