The Challenge

Security Threats Are Moving Below the Software Stack

Modern SoCs face physical and runtime attacks that manipulate voltage, clocking, thermal conditions, electromagnetic exposure, laser stimulation, timing behavior, and early execution states. These attack vectors often operate below the visibility of conventional software or firmware security controls.

▦

Protocol-Only Blind Spots

Software, firmware, and protocol security cannot always observe abnormal physical-layer behavior inside the silicon fabric.

⌁

Fault-Injection Attacks

Undervoltage manipulation, clock glitching, EMFI, and laser fault injection can corrupt execution at critical moments.

◈

Boot & Root-of-Trust Exposure

Early execution phases are especially sensitive because they establish trust, privileges, keys, and secure policy.

▣

Limited Runtime Visibility

Conventional security telemetry often lacks direct visibility into physical stress, timing anomalies, and silicon-level attack repetition.

Our Solution

Execution-Coupled Security Intelligence

VegaSecure™ introduces runtime silicon security based on direct observation of physical and micro-architectural execution behavior inside the SoC.

Instead of relying only on software-visible events, VegaSecure monitors abnormal timing behavior, voltage and clock stress, execution integrity deviations, and malicious physical stress patterns from within the functional execution fabric.

VegaSecure extends security awareness into the silicon runtime layer where physical attacks actually occur.

Architecture Overview

Runtime Security Architecture

VegaSecure combines execution integrity awareness, physical-layer anomaly detection, timing and stress observation, and security telemetry into a coordinated runtime security framework.

The architecture is designed to protect boot-critical and early execution phases while also supporting runtime attack detection, mitigation policy, and system-level security response.

  • Boot-critical and early-execution protection
  • Runtime execution integrity awareness
  • Voltage, clock, timing, and physical-stress anomaly detection
  • Fault-injection resilience against undervoltage, clock glitch
  • Physical-layer attack telemetry and repetition tracking
  • Integration with root-of-trust, security firmware, and system-level policy
