How can we strike a balance between security and performance in IoT devices, especially low-power ones, to ensure robust protection without compromising efficiency, potentially through the use of lightweight encryption and future blockchain-based technologies? @MCU, MPU & Firmware @PCB & Analog

This is an insanely loaded question but since you are already leading with lightweight encryption can you give us some sort of example?

But to what end? how much of your time are you running cryptography when you could be working. Would I use this in antilock brakes? I need security but I need timeliness more.

Ming•6/23/24, 4:43 PM

By doing risk analysis and threat modeling. You would start by looking at the value of the asset you are wanting to protect (hardware, functionality, IP, etc) and then working out the balance from the threats and the cost of protecting them.

For example, I only used AES128 on one of my low powered devices because the data it is protecting only has value for a short period of time, so the lower security is deemed ‘good enough’.

If the data was more valuable, then I would have had to use a more powerful device to enable stronger encryption.

Joseph Ogbonna•6/23/24, 4:49 PM

Oo. What other encryption level is higher than the AES

Ming•6/23/24, 4:56 PM

AES 192 and 256. These have longer keys and more rounds of processing (and therefore takes more computational effort to create).

Hey @here, @Event Pings, the next Engineering Hours is set for a week from today, June 30th, at the normal time of 15:00 GMT.

@Edison will be back to drop some knowledge on clocks and timers as we progress towards task management topics. You can sign up for an event reminder: https://discord.gg/enn7NEdH8w?event=1254450027711954956

FYI, we successfully streamed today on LI and YT so there will be multiple options to tune in on Sunday, but if you want to interact with Edison and the community the best place to join is the Engineering Hour stage here in Discord.

See you Sunday

Isn’t this precisely the intent behind ECC/ECC-DH? @Joseph Ogbonna are you asking about end to end encryption of all data?

Ttechielew Could you do both? Can your dad help arrange a part-time internship?

as per the poll conducted by @nour_oud , our server have lots of firmware developer .

Accur4te•6/26/24, 4:07 PM

i need a advice related to that field from the firmware developers here

Accur4te•6/26/24, 4:08 PM

What is the ideal roadmap to learn firmware development enough to master it at a intermediate level .

Accur4te•6/26/24, 4:08 PM

this are few udemy courses that i am looking forward to complete to learn firmware dev ( pls share your thoughts about it )

Of the two I would go for STM32 over ESP if you're considering commercial development. Also, the best way is probably to dive in but course 1 sounds like a good place to start if you need to start at the beginning.

What's the status of the internship you were considering?

For our @PCB & Analog and @Event Pings users, this Friday on Office Hours we're going to be looking at one @hemalchevli's journey into KiCAD development then on to Altium designer, diving into his experience and recommendations for each.

It starts on Friday at 15:00 GMT at https://discord.gg/cHNGvqMJG9?event=1254509681129291778

If you know what Chip they use, focus on that chip and learn it inside out. Specializing often ends up giving dispropotionate results.
