Example Application: TinyECC

TinyECC is a software package providing Elliptic Curve Cryptography (ECC) operations on TinyOS. It supports all elliptic curve operations over Fp, including point addition, point doubling and scalar point multiplication, as well as ECDSA operations over Fp (signature generation and verification). We plan to include other ECC schemes (e.g. ECDH, ECAES) in this package in the future.

  1. Node Configuration
  2. Code Generation
  3. Updating Makefile
  4. Build
  5. Run

 

  1. Node Configuration

#include "gen/cTinyECC_TinyOSModule.h"
#include "gen/cTinyECC_Main.h"

   cTinyECC_Main *m = new cTinyECC_Main(this,main,"Main",getIndex());
   m->StdControl_init();
   m->StdControl_start();
 

  1. Code Generation

NesCT is going to build all the classes in gen directory. Replace "cp" with "copy" and slash (/) with backslash (\) for windows operating system at the following instructions.


[root@sinan tictoc]# cd components/
[root@sinan components]# cp TinyECC.nc ../Application.nc
[root@sinan components]# cd ..
[root@sinan tictoc]# ./nesct.exe -DTOSH_DATA_LENGTH=102 Application.nc

done.
 

  1. Updating Makefile

  Type makemake.bat/makemake.sh to create new Makefile for Win32/Linux.

  1. Build

Type "make" to build the binary.


[root@sinan tictoc]# make
g++ -c -g -fpermissive -fPIC -DWITH_NETBUILDER -w -DTOSNODES=1000 -DLINUX -DPLATFORM_OMNETPP -I./include -I/root/projects/tinyos-1.x/tos/interfaces -I./include_tos -I/opt/omnetpp-3.2/include simstart.cc
g++ tictoc1_n.o debug.o simstart.o tinyos.o tinyosmain.o tossim.o txc1.o -g -L/opt/omnetpp-3.2/lib -lenvir -lcmdenv -lsim_std -lnedxml -lxml2 -ldl -lstdc++ -lpthread -o tictoc
echo>.tstamp

  1. Run

Let's enable all debug options for demonstration purposes. Use "export" keyword for linux and "set" keyword for windows to change environment variable. You should see an output similar to this in TK window.
