Quickly find out if this is the right IP for you with our semiconductor-trained AI assistant, Volt.

Description

ICTK's vPUF technology leverages the natural process variation in via holes to create a unique, highly secure inborn identity for use in secure applications. vPUF meets the ISO/IEC 20897 PUF specification and is silicon proven on major foundries, nodes, and processes.

Key characteristics include:

(1) Steadiness
(2) Randomness
(3) Tamper Resistance
(4) Uniqueness
(5) Physically Unclonable
(6) Mathematically Unclonable

Deliverables
Soft IP
  • Synthesizable RTL
  • Verilog integration testbench
  • Datasheet
  • Verification test bench and test vectors
Hard IP
  • Verilog
  • Datasheet
  • Integration guide
  • Test bench
Features
  • Root of Trust: The unique silicon-fingerprint acts as a secure anchor for trust in cryptographic operations
  • Digital Secret Key: The fingerprint serves as a secret key for encrypting data and authenticating devices.
  • Crypto Root Key: The secret vPUF key is self-generated within the chip and never leaves it, existing only when the power is ON
  • Unique Inborn ID: vPUF provides unique silicon "Inborn ID", so no key injection is needed
  • Key Chain Generation: vPUF allows for the creation of secure keys derived from a single source, enhancing key management
  • No Error Correction Code: vPUF's reliability means there's no need for error correction code, simplifying the key process
  • Implementation using standard ASIC flow: vPUF bitcells are standard cells recognized by automatic place-and-route tools
  • Camouflaged among Logic Cells: vPUF cells are randomly distributed on the chip, making it difficult to distinguish them from regular logic cells
  • ISO/IEC 20897 Compliant: vPUF has been tested in accordance with the ISO/IEC PUF standards for security requirements and test methods
