Test Schedule

• Test 1
• Set-up (Two motes with TestTinySec)
• Result
• Test 2
• Set-up (One mote with TestTinySec, one with
  SecureTOSBase)
• Result
• Test 3
• Set-up (Simulation of two motes with
  TestTinySec)
• Result
• Test 4
• Set-up (Simulation of two motes with TinyViz)
• Result

5
Test 1

• Set-up
• Test application TestTinySec (using
  SecureGenericCommSenSecM)
• Compile TestTinySec and install them on two
  motes
• Encrypted and authenticated packets are sent
  between these two motes
• Result
• Mote sending an encrypted and authenticated
  packet successfully will toggle Green
• Mote receiving an encrypted and authenticated
  packet successfully will toggle Red
• Two motes will have Green and Red blinking
• Otherwise, no blink.

6
Test 2

• Set-up
• Test application TestTinySec (using
  SecureGenericCommSenSecM)
• Compile TestTinySec and install it on mote 1
• Test application SecureTOSBase (using
  SecureGenericCommSenSecM)
• Compile SecureTOSBase and install it on mote 2
• Encrypted and authenticated packets are sent
  from mote 1 to mote 2
• Result
• Mote 1 sending an encrypted and authenticated
  packet successfully will toggle Green
• Mote 2 receiving an encrypted and authenticated
  packet successfully will toggle Red
• PC using Listen tools on MOTECOMserial_at_COM15760
  0 sees Raw data
• Otherwise, no data shown.

7
Test 3

• Set-up
• Test application TestTinySec (using our
  implemented components SenSec-EA)
• Compile TestTinySec with make pc
• Run build/pc/main.exe 2 gt result.txt with
  DBGusr1,crypto,am
• Encrypted and authenticated packets are sent
  between two simulated motes
• Result
• Mote 0 (sees every byte sent, encrypted, MAC
  value computed)
• Mote 1 (sees every byte received, decrypted,
  acknowledge if MAC is verified)
• Otherwise, fail.

8
Test 3 (contd)

• Set-up
• Test application TestTinySec1 (using
  SecureGenericComm)
• Compile TestTinySec1 with make pc f Makefile1
• Run build/pc/main.exe 2 gt result1.txt with
  DBGusr1,crypto,am
• Authenticate-only packets are sent between two
  simulated motes
• Result
• Mote 0 (sees every byte sent, MAC value
  computed)
• Mote 1 (sees every byte received, acknowledge if
  MAC is verified)
• Otherwise, fail.

9
Test 3 (contd)

• Set-up
• Test application TestTinySec2 (using
  SecureGenericComm with CRC)
• Compile TestTinySec2 with make pc f Makefile2
• Run build/pc/main.exe 2 gt result2.txt with
  DBGusr1,crypto,am,crc
• Checksum packets are sent between two simulated
  motes
• Result
• Mote 0 (sees every byte sent, CRC value
  computed)
• Mote 1 (sees every byte received, acknowledge if
  CRC is verified)
• Otherwise, fail.

10
Test 4

• Set-up
• Test application TestTinySec (using
  SecureGenericCommSenSecM)
• Compile TestTinySec with make pc
• Test application TinyViz (compile and run)
• Run TinyViz run build/pc/main.exe 2 with
  debug plugin
• Encrypted and authenticated packets are sent
  between two simulated motes
• Result
• A visual simulation environment is shown
• Mote 0 (sees every byte sent, MAC value
  computed)
• Mote 1 (sees every byte received, acknowledge if
  MAC is verified)
• Not always successful.

11
Next

• Name changing (less confusing)
• Performance analysis
• Tackle packetlt8 bytes problem (very difficult)
• TPSN integration (why need another time
  synchronization?)
• TinyOS-1.1.7 (TinySec improves on some
  components)
