Solution Brief: PQMicroLib-Core-for-SCA-Protected-Post-Quantum-Keys-in-Embedded-Devices

Abstract

Protect long-lived PQC secrets without hardware redesign

The Challenge

Embedded and IoT devices increasingly rely on long-lived private keys that must remain secure in the field for 10–20 years. With the transition to Post-Quantum Cryptography (PQC), the risk profile is expanding. Private keys are large and complex, meaning mathematical operations are computationally more intense, in turn leading to implementations that are inherently more exposed to side-channel attack (SCA). Edge devices are particularly vulnerable. Additionally, many brownfield devices cannot be redesigned or afford secure elements, despite constant security requirements. Because devices shipped today must survive the quantum transition window, there is a structural gap between deployable solutions and the required assurance levels.

The Solution

PQShield delivers DPA-protected solutions to defend long-lived PQC secrets against physical attacks. PQMicroLib-Core Edge Grade, designed for exposed, embedded environments, provides:

  • Pure software side-channel countermeasures
  • Deployable Over The Air (OTA)
  • No special hardware required

For customers requiring higher coverage, invasive attack resistance, greenfield devices, or additional performance, PQPlatform provides the next assurance step.
