Open hardware-based and patent-free Physical Unclonable Function (PUF)

[synctext]

PUF technology is an emerging technology to store the essential part of a self-sovereign identity, the private key, in a tamper-proof manner. The private key is storage becomes volatile by using PUF technology [Patents].

Good intro:

• "Physically Unclonable Functions: A Study on the State of the Art and Future Research Directions"
• MIT intro slides

Commercial product with SRAM PUF. Notes on how to use this feature

For TUDelft publication on PUF technology: "Modeling SRAM start-up behavior for physical unclonable functions". Lots more by Said Hamdioui plus Haji Akhundov. More Delft reports:

• Design & development of public-key based authentication architecture for IoT devices using PUF
• Reliability Assessment and Test Methods for Anti-counterfeiting Technology
• More sophisticated 2015 work PUFs in general, SRAM PUFs in particular, can be used as a secure cryptographic key storage mechanism . Fig. 1 shows how such mechanism can be integrated to create a PUF based key storage system.

The popular 6Ts SRAM cell (see Fig. 2(a)) consists of two cross-coupled CMOS inverters formed by four transistors (Q 1 with Q5 and Q2 with Q6) and two pass transistors (Q3 and Q4). The pass transistors are used to access the cell for read and write operations. The bitline (BL), the compliment bitline (BLB) and the wordline (WL) are used to access the cell.

We simulate the start-up behavior of an SRAM cell using SPICE and BSIM4 65nm models. Process variation PDF for 65nm :

Boris Škorić from Eindhoven has published work in this field:

• exotic quantum theory work, Quantum Key Recycling with eight-state encoding (The Quantum One Time Pad is more interesting than we thought)

Hello,

I am working on my thesis "MAchine learning attacks on DRAM PUF" as part of my thesis, am currently looking for a dataset If anyone has a DRAM PUF dataset it would be really helpful.

interesting, machine learning attacks.. Have you seen the data above 'result of 10 SRAMs 23LC1024: • Length of bits: 524288'

Lots of detailed data
