Hey there,
How are you doing? Okay, so I understand that you're looking for someone to implement a PUF solution to encrypt tags. I have taken note that you've seen 2 solutions so far - Semi-Randomized Access Control or a physical unclonable function. I will explain in great detail during discussion which one is more suitable. Let me ask you something:
1. Do you want the security for your products? (so you can fetch product info)
2. What is the deadline for this project?
I have excellent work history, top ratings & feedback from my clients, so I assure you that you're in the right hands. If you have any questions or concerns, please let me know at earliest.
Sincerely,
Wasif
