Stop reverse-engineering

SypherMedia Library (SML) Circuit Camouflage Technology is an anti-reverse engineering and anti-cloning protection for integrated circuits that has both Commercial and Government Applications. The Circuit Camouflage Technology significantly increases the level of difficulty while decreasing reliability of reverse engineering efforts of a circuit.

Technologies specifically designed for Anti-Tamper, Intellectual Property protection and Cloning Prevention

With worldwide applications rights and over 50 granted US patents and numerous international patents, Inside Secure has developed the know-how and proprietary trade secret techniques uniquely positioned to implement these designs. We offer training and licensing options, enabling your design team to implement SML circuit camouflage technology on your devices as well as a range of courses in hardening silicon IP to reverse engineering, cloning, and tamper attacks.

The Circuit Camouflage Technology has never been successfully reverse engineered leading to a pirated part. SML is a unique and innovative technology that when incorporated into an ASIC design, makes the silicon itself resisting reverse-engineering attacks. SML utilizes foundry standard cells, standard tools and design methodology, doesn’t rely on coatings or shields, and provides a high return on investment for silicon manufacturers, chip makers wanting Intellectual Property protection and having products in high attack environments.

The SML is available in silicon technologies down to 28nm and Inside Secure is currently working on a project in FINFET 14nm.

Extend the lifetime of your silicon designs and protect your critical intellectual property

Using these designs and techniques, chip makers keep sensitive and strategic aspects of custom designs secret from competitors and counterfeiters, providing hardware protection to secure intellectual properties. Additionally, Inside Secure's Camo SmartFill provides high tamper resistance from unauthorized modifications to the design by filling the entire chip with circuitry allowing attackers no space in which to insert a Trojan circuit without destroying the underlying function of the ASIC.

In summary, Inside Secures's Circuit Camouflage Technology together with Camo SmartFill:

  • Keeps designs secret from competitors and counterfeiters 
  • Protects against state-of-the-art circuit extraction attacks
  • Is applicable to any CMOS process and any digital design
  • Significantly extends the security life of your product
  • Is low-risk technology that has been in practice for over 20 years
  • Easily applies to any standard cell design flow
  • Minimal impacts area, performance, and power consumption
  • Camouflage of analog IP is also available
  • Secures design during device manufacturing


Normal AND2 gate


Camouflage AND2 gate

The camouflage AND2 gate appears identical to the normal AND2 gate. It performs a different logic function. A reverse engineer mistakenly interpreting both gates as normal AND2 gates would extract an incorrect netlist from silicon.

Circuit Camouflage Industry Testimonials

"Inside Secure's SypherMedia Library(TM) Circuit Camouflage Technology has been successfully integrated by Infineon Technologies into customer specific products."

Infineon Technologies

"The SypherMedia Library™ Circuit Camouflage is the most effective hardware intellectual property protection solution I have encountered. To analyze and extract the functionality of even a small number of cells is a daunting task. An ASIC secured by Inside Secure's Circuit Camouflage Technology is highly resistant to even the most sophisticated and modern reverse engineering and circuit extraction attacks. I have had the opportunity to evaluate their technical approaches over the past number of years and can attest that their methodology has far outpaced that of the reverse engineering community."

Michael Strizich - President - Analytical Solutions, Inc. 

"Inside Secure's Circuit Camouflage Technology provides a powerful layer of defense against reverse engineering and circuit extraction of semiconductor chips. To prevent pirating, our CryptoFirewall™ cores for pay TV applications must withstand a broad range of attacks. The ability of Inside Secure's technology to help secure the underlying ASIC circuitry is beneficial to the industry."

Paul Kocher - President & Chief Scientist - Cryptography Research, Inc. 

"Whether the end application concerns national security, prevention of commercial espionage, or otherwise, Inside Secure's technology is an essential part of any chip-level IP protection plan."

Jeff Draper - Information Sciences Institute - Researcher and DARPA Project Contributor

"Inside Secure's Circuit Camouflage Technology is an innovative and effective technology to prevent reverse engineering and circuit extraction of any fabricated design. Tela Innovations has worked with Inside Secure to demonstrate in silicon how the combination of our layout style and Inside Secure's Camouflage Technology can create a substantial barrier for analysis labs to obtain a functional netlist. This greatly extends the security life and adds value to fielded designs. This intellectual property protection and anti-cloning technology is a great complement to commercial and government designs and significantly enhances the overall security of hardware products."
