...ERC-standards, and, where it makes sense, an L2 or private side-chain—yet the architecture must still communicate with other chains for true interoperability. Here’s the flow I have in mind: • On-chain smart contracts store only encrypted hashes/pointers; actual PHI lives off-chain (IPFS, Filecoin, or an encrypted database—open to your recommendation). • Role-based permissions and public-key cryptography determine who can write or read a record, aligning with HIPAA requirements. • A lightweight middleware layer (REST or GraphQL) bridges existing EHR systems and handles FHIR mapping so providers can plug in with minimal refactoring. • Cross-chain messaging or bridging (e.g., Chainlink CCIP, LayerZero, or a custom relay) proves that a re...

I’m putting together the written component of a university-level course project on cryptography and data protection, and I want the documentation to revolve squarely around modern encryption techniques. The content must walk students step-by-step through symmetric encryption, asymmetric encryption, and the most common cryptographic hash functions, explaining how each works, why it matters, and where it is typically applied. What I need from you is a clear, well-structured document (approximately 25–30 pages, though quality comes first) that blends theory with concise, real-world examples. Include diagrams or simple code snippets where they genuinely help comprehension, but keep the narrative accessible to students encountering these ideas for the first time. Deliverab...

...in the full Signal protocol—X3DH for the first handshake, ECDH+Double Ratchet for forward secrecy, AES-GCM-256 with HKDF-HMAC-SHA-256 for payload protection. On paper everything looks correct, yet in practice messages still slip out in plaintext or throw a “failed to send” error whenever the recipient hasn’t generated keys or an old session is corrupted. What I need now is an experienced cryptography engineer who has actually debugged Signal-based stacks to step in right away, review my current implementation and make the encryption rock-solid. The most pressing pain point is the message-encryption phase itself; sessions sometimes never initialise or silently fall back to no cipher at all. Deliverables I expect: • Diagnose why sessions aren&rs...

I’m running an R-and-D exploration into privacy-preserving spiking neural networks and need a compact proof-of-concept written in Python. The core idea is to take a small SNN model, encrypt its inputs (and ideally weights or activations) with a well-known fully homomorphic encryption (FHE) scheme, run inference while data remains encrypted, ...Acceptance criteria • Decrypted outputs match plaintext inference within an acceptable error tolerance you specify up front. • All code executes end-to-end on a standard CPU environment (no GPUs required). • No hard-coded paths or proprietary data. This is experimental work, so clarity and reproducibility matter more than raw speed. If you enjoy pushing the edge of neural computation and cryptography, I’d lo...
