Crypto 3: Modular Embedded Security Testing for Side Channel and Fault Injection Analysis
We are pleased to introduce a significant advancement in embedded security testing: Crypto 3, the newest framework driving Inspector Software’s next-generation security analysis. Available starting with Inspector Software 2025.8, this release redefines how side channel analysis and fault injection testing are designed, executed, and automated—making advanced security testing more accessible to teams of all skill levels.
A Shift from Monolithic to Modular Security Testing
With more than 20 years of experience in embedded security validation, Inspector Software has delivered over 100 dedicated modules supporting side channel analysis (SCA) and fault injection (FI) techniques. While the existing Crypto 2 framework offers a comprehensive, all-in-one approach, adapting it to specific attack scenarios often requires deep expertise and considerable development effort.
Crypto 3 changes this model entirely. Its modular architecture enables faster configuration, intelligent automation, and fine-grained control—streamlining security workflows without sacrificing analytical depth.

Crypto 3 changes this model entirely. Its modular architecture enables faster configuration, intelligent automation, and fine-grained control—streamlining security workflows without sacrificing analytical depth.
Key Advantages of Crypto 3
- Reduced Development Effort: Achieve equivalent analysis results with significantly less code by implementing only the attack components you actually need.
- Faster Security Validation: Simplified workflows accelerate testing cycles, helping teams identify vulnerabilities earlier and shorten time-to-market.
- Greater Adaptability: A block-based design allows selective use of functionality, seamless integration of custom cipher implementations, and easier collaboration across teams with varying expertise.
- Prepared for the Future: Built-in extensibility and support for Post-Quantum Cryptography (PQC) allow rapid response to evolving cryptographic standards and attack techniques.
- Seamless Continuity: Crypto 2 remains fully supported, ensuring existing workflows continue uninterrupted while users transition to Crypto 3 at their own pace.
How Crypto 3 Works in Practice
Developed by our device security engineering experts, Crypto 3 introduces a simplified and modular approach to cryptographic analysis. Instead of requiring full knowledge of a complete cipher or Inspector’s internal structure, functionality is divided into independent, purpose-driven building blocks.
This design allows users to generate only the intermediate values or components required for a specific attack. For example, if an analysis depends on a single internal cipher value, Crypto 3 enables direct access without navigating complex dependencies—saving time and reducing unnecessary complexity.
At the same time, Crypto 3 maintains full backward compatibility. Users can continue using existing cipher implementations within Inspector or integrate their own, while benefiting from the efficiency and flexibility of the new framework.
Designed for Post-Quantum Agility
As Post-Quantum Cryptography continues to evolve, security testing faces new challenges. Cipher designs change rapidly, and investing heavily in one-off implementations can limit experimentation and innovation.
Crypto 3 addresses this challenge by enabling rapid prototyping and iterative testing. Its modular structure allows users to define only the components relevant to their current objective, making it easier to explore new attacks and cipher concepts without extensive integration overhead.
Additionally, many PQC algorithms involve extremely large key spaces, making exhaustive analysis impractical. Crypto 3 supports smarter analysis by allowing users to concentrate on the most relevant key candidates—improving efficiency while maintaining analytical rigor.
