>> LIBCOMMAS - AUTHENTICATED MESSAGING FOR RESOURCE-LIMITED DEVICES
It seems the message of IoT security is gaining momentum as a must fix.
With security being a hot-topic in the IoT industry - it is natural to
see efforts appear to help solve the problem;
recently published an open-source library of their own providing elliptic
curve cryptographic (ECDSA) digital signing and industry accepted (SHA-2)
hashing algorithms to provide a secure machine to machine messaging framework.
I have covered a number of IoT security topics, ranging from the
commercial web cameras
that get hacked to watch you, efforts to
expose devices to hacking to expose design flaws, question the
of implementing security into micro-controllers,
efforts to create a
secure bare-bones operating system through to the extreme
concepts of modelling
to provide a defensive mechanism within an IoT deployment.
The team hit the nail right on the head with their approach:
The aforementioned "resource-constrained" platform is none other than the
all mighty and cheap Arduino UNO (Atmel AVR 8-bit CPU with 2KB SRAM,
32KB flash, and 1KB EEPROM).
I am sure I could optimize the code a little from a code size and memory
usage perspective (the use of EEPROM for memory isn't best practice)
and look at a way of integrating it with what I have already done with
RSA encryption - if only there were enough hours in the day!
The library, known as "libCommas" is hosted on
and has been released under the Apache version 2.0 open source license, a
developer friendly license that allows for quick and easy adoption of
open source into both commercial and non-commercial software. I am sure
that their efforts will not go in vain and it will be of great assistance
to many out there.
