EndoSec Products Overview


EndoSec Encryption Products

EndoSec specializes in creating robust implementations of cryptographic algorithms which are resistant to a number of advanced attacks. Our algorithms are typically available in both firmware and software. Firmware cores are ready for implementation in silicon.

EndoSec Encryption products are NIST/NSA Suite B (Vanilla Algorithms) that support:

  • Advanced Encryption Standard (AES)
  • Elliptic Curve Diffie-Hellman (ECDH)
  • Elliptic Curve Digital Signature Algorithm (ECDSA)
  • Secure Hash Algorithm (SHA)

All of the NIST/NSA Suite B algorithms are available as standard cores, high speed variants, or 'secured'. We can custom tailor the cores to the specific application.

EndoSec 'Hardened' Cryptographic Modules

The EndoSec 'hardened' cryptographic modules consist of additional techniques to protect from advanced attackers. EndoSec has baseline algorithms that are easily adjusted to fit customer's needs: speed vs. security vs. gate usage.

The EndoSec cores work well in all ASIC and FPGA parts and are customized to fit each target and exploit the resources in the most useful way.

All the above modules were developed by EndoSec using US Citizens and Cleared personnel.

Intrinsic ID Product Overview

EndoSec is a Government, Aerospace, and Defense reseller for Intrinsic ID USA. Intrinsic ID is the world pioneer and leader in Physically Unclonable Function (PUF technology) security IP cores using its patented Hardware Intrinsic Security technology(tm) (HIS). Originated from Philips Research, Intrinsic ID has established itself as a leading provider of strong security solutions for combating digital security hazards worldwide.

Intrinsic-ID has developed an efficient and highly secure key storage solution. This is accomplished through Hardware Intrinsic Security or HIS technology. HIS represents an innovative and system-wide design methodology for deploying a key storage solution founded on Physically Unclonable Functions or PUFs.

Intrinsic-ID's HIS products take PUFs to the next level in security. They overcome several weaknesses of traditional embedded key storage technologies. They come with integration guidelines depending on the security level that is required. Intrinsic-ID's HIS products are implemented in ICs that are target for security evaluations. HIS technology has been extensively tested and approved by security experts at major entities, such as Philips, Thales, SiVenture, NXP, Microsemi, and a major US defense contractor. So far, no successful attacks have been reported. Immunity against sophisticated attacks and successful evaluations by major entities show that HIS-based products are ready for adoption in high security systems.

Quiddikey Functionality

Software-Hardware Binding

Using Quiddikey(c) a software image is bound to a specific device using its intrinsic security elements hidden in the hardware and a revolutionary approach based on a secure implementation of Physically Unclonable Functions (PUFs) called Hardware Intrinsic Security(tm). This can be achieved with device unique random keys as well as with a global protection key.

Decryption Without Storing Keys

Quiddikey(c) is the sole and unique security solution in the market which dynamically reconstructs the on-chip secret key used for secure file and software decryption without ever storing that key. This means that the key is not present on the device when it is powered off, but generated on-the-fly using Hardware Intrinsic Security (tm) every time it is needed. It defeats the most advanced invasive hardware attacks on the key itself by simply not storing it.

PUF Is Ideally Suited To Provide Root Of Trust

Quiddikey provides Root of Trust security to the highest level of trust.

  • No key material can be extracted when device is off
  • Truly independent root of trust
  • High quality and independent true entropy source
  • Based on well researched PUF and crypto principles
  • Quiddikey and Secure Boot

    Quiddikey is a flexible hardware key storage solution that does not store the key but reconstructs it on-the-fly from the internal hardware intrinsic properties of the device. In this way Quiddikey provides a totally flexible, low cost and efficient secure boot solution for Flash based systems.

    Cloning and Counterfeiting Protection

    Copying the Quiddikey generated activation code from one device to another results in a non-functional device since the data extracted from the chips of another device do not match with this activation code and will result in the wrong key being reconstructed, thus protecting such systems against cloning and counterfeiting attacks simultaneously.

    Security decisions can affect your systems for years to come. Our security engineering services enable you to feel more confident about the actions you take to secure your systems.

    EndoSec has decades of experience advising companies. We can help you create a robust security environment with services that include current and emerging threat assessments, policy review and development, and master planning.

    There are many components to protecting intellectual property. By looking at your security challenges from several vantage points, our security specialists can help you better prevent, plan for, and respond to threats.

    PUFs are innovative circuit elements but are on their own not sufficient to protect a system's security. They need to be integrated properly into a security product. Building a security product encompasses much more than simply adding functional blocks. Extreme care must be taken when designing such a product and integrating its components. Any addition to a system may introduce weaknesses if it is not done in a professional, secure and savvy way. The HIS methodology is based on years of research and development, and encompasses among other things the design choices for the PUF itself, innovations, optimizations and protective measures for the key generator, as well as system-wide guidelines for implementing and integrating a HIS design into a product.
