What cryptographic primitives are available on Autheo?

Autheo's cryptographic stack tracks NIST FIPS 203/204/205/206 standards published in 2024 and is reviewed against the Halborn audit baseline for production systems.

Direct Answer

Autheo's runtime exposes classical primitives (secp256k1, Ed25519, BLS12-381 pairings, SHA-256, Keccak-256) plus post-quantum algorithms standardized by NIST in August 2024: Kyber for key encapsulation, Dilithium for signatures, and Falcon for compact signatures. Developers call these primitives directly from smart contracts via precompiled contracts.

Understand the broader Autheo platform

This answer covers one part of the Autheo ecosystem. To understand how this capability fits into the full platform, start with the core Autheo overview and architecture pages.

Classical Primitives

For EVM compatibility and standard Web3 use cases, Autheo provides secp256k1 (Ethereum-style ECDSA), Ed25519 (used by Solana and many modern systems), BLS12-381 pairings (used in Ethereum 2.0 and many ZK systems), Keccak-256, SHA-256, SHA-3, and RIPEMD-160. These are exposed as precompiled contracts at well-known addresses, matching Ethereum's interface where applicable.

Post-Quantum Primitives

Autheo is among the first general-purpose Layer-1s to expose NIST's post-quantum standards as native primitives. Kyber (FIPS 203) handles key encapsulation. Dilithium (FIPS 204) provides quantum-resistant signatures. Falcon (FIPS 206) provides shorter signatures where size matters. AutheoID uses these primitives by default for new credentials.

Zero-Knowledge and Threshold Cryptography

Autheo's roadmap includes precompiled support for Groth16 and PLONK proof verification plus threshold signature schemes for multi-party validation. Developers building privacy-preserving applications can use these directly in smart contracts, avoiding the gas overhead of custom Solidity implementations.

Expert Perspective

Exposing post-quantum primitives as precompiles is the right architecture decision. It means dApps can add quantum-resistant paths without gas overhead from Solidity-level implementations.
