The Secure Device Connection Protocol (SDCP), is designed to enable secure
biometrics with fingerprint sensors, providing a mechanism to ensure that:
The device is trusted.
The device is healthy.
The input from the device is protected.
Thorough documentation can be found on the
wiki.
Sample Client Implementation
This repository contains a sample client implementation of the protocol
documented in the wiki, using the mbed TLS library,
which must be obtained and installed prior to building the sample.
Build
To build this sample, the mbed TLS library must have already been built and
installed on your system. CMake and a C compiler for your platform are required.
Linux (Tested on Windows Subsystem for Linux, using Ubuntu)
git clone https://github.com/Microsoft/SecureDeviceConnectionProtocol.git
cd SecureDeviceConnectionProtocol
mkdir build
cd build
cmake ..
make
Windows (With Visual Studio)
git clone https://github.com/Microsoft/SecureDeviceConnectionProtocol.git
cd SecureDeviceConnectionProtocol
mkdir build
cd build
cmake ..
And then open sdcp.sln with Visual Studio
Test
This repository contains a test executable, sdcptest, that can be used to
generate test vectors for your own client implementation of the protocol, and
can be used as a reference for the expected calling pattern of the client
functions. Example output:
