A port of WSNProtectLayer (https://github.com/crocs-muni/WSNProtectLayer) for (Arduino-compatible) JeeLink/JeeNode devices providing a subset of WSNProtectLayer's features.
- AES encryption and MAC for secure communication
- μTESLA authenticated broadcast
- Neighbor discovery
- Simplified CTP protocol
- Configurator for nodes' IDs and pairwise keys
The project is written in C++ and requires g++ to build Linux host applications and avr-gcc compiler to build JeeLink part. EduHoc (https://github.com/crocs-muni/Edu-hoc) project is also required to build and upload JeeLink applications. EDU_HOC_HOME variable needs to be set to EduHoc directory. To build everything, run make in project directory:
makeAfter this, configurator host config_host is located in Configurator/host together with the library libconfigurator.a, base station host library libcommon.a is located in ProtectLayer/common and AES library libaes.a in ProtectLayer/common/AES. Target directory of JeeLink applications is $EDU_HOC_HOME/bin/mini328/. To use library in JeeLink devices, please see the demo applications in ProtectLayer directory.
For now, JeeLink applications are uploaded by first version of JeeTool included in EduHoc project.
Example:
cd /path/to/this/project
java -cp /path/to/JeeTool cz.muni.fi.crocs.EduHoc.Main -a /file/with/JeeLinks/paths -u ProtectLayer/demoThis example uploads the demo application to nodes listed in /file/with/JeeLinks/paths.
The network consists of regular nodes and a single base station. Base station consists of master running in Linux host and a slave as it requires more resources than a JeeLink device can provide. Slave device serves only as a radio.
ProtectLayer directory contains base station slave (BS_slave directory), all the library sources common for both Linux base station and JeeLink devices (common directory) and 3 demo applications to present possible use cases.
Configurator directory contains both Linux host application and JeeLink application to configure the device.
As stated above, Configurator is used to configure devices. It takes an input file consisting of lines containing path to devices and their IDs. There is an example config file config in Configurator/host. Configurator can generate, save and upload keys to the JeeLink devices. Please run it with argument -h to see the options. To perform the configuration, a JeeLink part must be already uploaded and running in the devices.
