Required C,Cryptography,Elliptic Curve Cryptography (ECC),Information Security Audit,Let's Encrypt freelancer for Design Secure AES Block Cipher job

Objective is to design and implement a block cipher (AES) resistant to physical attacks (side-channel
attacks) such as CPA (Correlation Power Analysis) so it become impractical* to recover the secret
key.

Additional information:
+ Programming language: embedded C
+ Targeted hardware architecture: ARM Cortex M
+ AES HW accelerator is available through the software crypto libraries
+ AES Block Cipher Key size = 128 bit
+ Plaintext is known to an attacker

* to mounting the successful attack would require enormous efforts/money and time
