Mathematical Foundations

Formal verification of cryptographic assumptions, hardness proofs, and security reductions.

2

Protocol Design

Analysis of protocol composition, message flows, and adversarial model coverage.

3

Implementation Security

Code review for timing attacks, memory safety, and cryptographic API misuse.

4

Hardware & Side-Channels

Assessment of TEE integration, HSM usage, and physical attack resistance.

FAQ

Frequently Asked Questions

A cryptography audit is a specialized security assessment that examines cryptographic systems at multiple layers: mathematical foundations, protocol design, implementation correctness, and hardware/side-channel resistance. Unlike general security audits, cryptography audits require deep expertise in number theory, algebra, and formal methods to identify subtle flaws that could compromise the entire system.

We audit the full spectrum of modern cryptography: zero-knowledge proof systems (zkSNARKs, zkSTARKs, Plonk, Halo2), multi-party computation protocols, fully homomorphic encryption schemes, post-quantum cryptography implementations, classical primitives (ECDSA, BLS, AES), and ZK-friendly hash functions. Our team has hands-on experience with production deployments across all these domains.

Duration depends on complexity. A focused review of a single cryptographic primitive typically takes 2 to 4 weeks. Comprehensive audits of ZK circuits or MPC protocols usually require 4 to 8 weeks. Full-stack assessments covering multiple cryptographic components may take 8 to 12 weeks. We provide detailed timelines during scoping.

No, they are complementary. A smart contract audit focuses on business logic, access controls, and Solidity/Rust-specific vulnerabilities. A cryptography audit examines the underlying cryptographic primitives, proofs, and protocols. Projects using ZK proofs, threshold signatures, or custom cryptography typically need both types of audits.

Yes. We map all findings to relevant standards including NIST SP 800-series, FIPS 140-3, ISO 27001, and CFRG recommendations. This documentation helps satisfy due diligence requirements from partners, exchanges, and regulators, and accelerates compliance processes.

Cryptographic code can be syntactically correct but mathematically broken. Issues like incorrect curve parameters, missing domain separation, or flawed proof composition require specialized knowledge to detect. Our auditors combine formal methods expertise with practical attack experience to find vulnerabilities that general security tools miss.
