Hello everybody,Does anybody knows about how to encrypt, sign and write firmware to flash using CEC172 at MPLABX? I have already written my ECDSA and ECDH keys to eFuse, but I don't how to do the writing of to firmware to flash. The boot process isn't well explained at the datasheet also, so I don't..
I'm trying to use DM990013 - CEC1x02 Development Board with CEC1702 microcontroller, but I'm having trouble with initial setup.
I read the datasheet and I'm aware of programming eFuse. I don't know how, the datasheet covers only Clicker Boards and I'm using Microchip default boar..
I want to use the ATECCs' KDF command in HKDF mode, however I am not able to get the result I am looking for.
A short summary from RFC-5869: HKDF consists of two steps, extract and expand. Extract takes as input a IKM (input keying material) and a salt (optional) and creates a PRK (pseu..
Hello, Goal: Accomplish a frame signature using the hash SHA256 of some data. What is the error I'm getting: When I run the sign command, 0x0F status byte is returned, meaning that despite the command was correctly received by the chip, the current state of the chip does not allow to generate a sign..
Hello, I've been using ATECC608A and I'm with some issues to achieve what I need (probably my fault). So, before using ATECC608A I was using a cryptographic built-in library (MBedTLS) and running it on a uC (XMC4500). To sign and verify frames, (1) I've created externally two public/private RSA 1024..
Hello, Context:I am evaluating a secure 4 click (MikroElectronika) which has an ATECC608A. I want to accomplish the following actions: Generate unique private/public keys, sign, verify signs and ecdh encryption. I am using an XMC4500 which communicates via I2C with the ATECC608A. Problem:Despite the..
Sorry I'm a newbie. It is possible to set an encryption password for all chips using the programmer.
So I know what the password is without having to read the control? It is possible to select the time when CHIP sends the protocols.
Example: send 50 times with a click of the button?..
