PROVEN FRAMEWORK
Our Homomorphic Encryption Audit Methodology
Our systematic, multi-layered audit process is designed to uncover critical vulnerabilities in FHE implementations, ensuring your protocol's mathematical integrity and operational security before mainnet launch.
01
Cryptographic Protocol Review
We conduct a foundational analysis of your FHE scheme (e.g., CKKS, BFV, BGV) to verify correct implementation, parameter selection, and resistance against known lattice-based attacks.

EXPERTISE MATTERS
Why Choose a Specialized Audit
Homomorphic encryption protocols are a critical frontier in privacy-preserving computation. A generic smart contract audit is insufficient to uncover the subtle cryptographic and mathematical vulnerabilities that can compromise data integrity and user privacy. Our specialized audit delivers the depth of expertise your project requires.
04
Performance & Gas Optimization
Homomorphic operations are computationally intensive. We audit for gas inefficiencies on-chain and performance bottlenecks off-chain, providing actionable recommendations to reduce operational costs by up to 40% while maintaining security guarantees.

Technical Deep Dive
Homomorphic Encryption Audit FAQs
Get clear, expert answers to the most common questions about our specialized audit process for privacy-preserving protocols using homomorphic encryption.
Our audit follows a rigorous, multi-layered methodology tailored for cryptographic protocols. We conduct 1) Protocol Logic Review to verify the mathematical soundness of the HE scheme (e.g., CKKS, BFV) against the whitepaper. 2) Implementation Security Analysis, where we examine the code for side-channel vulnerabilities, parameter misuse, and correctness of operations. 3) Integration Audit, assessing how the HE layer interacts with the broader application (smart contracts, oracles, key management). This structured approach, refined over 20+ privacy-focused audits, ensures we catch both cryptographic and systemic risks.
