📄️ Mobile Hardware Security
Interstellar leverages the Secure Element (SE) or Trusted Execution Environment (TEE) embedded in modern smartphones to generate and store a proxy private key that is never accessible to the OS or app layer. This proxy key enables passwordless, tamper-resistant authentication that is compliant with FIDO2/WebAuthn elliptic curve standards and can be integrated as a decentralized passkey solution.
📄️ Garbled Circuits
Garbled Circuits are a cryptographic primitive originally introduced by Andrew Yao, designed to enable secure two-party computation. One party (the "garbler") encrypts a circuit such that another party (the "evaluator") can compute the output without learning any of the underlying inputs or internal logic. Interstellar adapts this concept to build tamper-resistant one-time programs for secure transaction and authentication workflows.
📄️ Dynamic Visual Cryptography
Interstellar integrates a novel form of Dynamic Visual Cryptography (DVC) as a human-centric defense layer for critical wallet interactions. This system uses cryptographic animation-like sequences called visual cryptographic shares to render transaction validation information in a way that is perceptible only to the human eye—yet meaningless to software or malware.
📄️ Decentralized Backend
Interstellar’s architecture is built around a decentralized backend designed to manage critical authentication, transaction processing, and smart account functionality with no reliance on centralized servers or custodians. Unlike traditional wallet stacks, where security-critical logic is handled by backend APIs or cloud infrastructure, Interstellar decentralizes every sensitive operation into verifiable and tamper-resistant blockchain components.
📄️ Sybil-Resistant Asset Distribution
Interstellar’s airdrop and onboarding engine is designed to be resilient against Sybil attacks, using a decentralized combination of secure hardware attestation, dynamic visual cryptography, and on-chain enforcement to validate the presence of a real human on a real device—without relying on traditional KYC, CAPTCHAs, or centralized account reputation systems.
