What about Post Quantum Cryptography? A topic that is becoming more and more trendy! France is at the forefront, with world-class researchers from Inria Irisa and more! → the PQCrypto2026 event has just kicked off in Saint-Malo, France, and we at Katvio.com are thrilled to be there! Post-quantum crypto is directly relevant to several internal projects we're working on: → MPC-Signing: multi-party computation signing as a stronger alternative to classic KMS solutions (see https://lnkd.in/eXUhJzaE) → DKG (distributed key generation) → Fractum: an enterprise-grade encryption tool that employs crypto algorithms for long-term cold storage of critical information (see https://lnkd.in/eRVmhA8Z) If you're at the event or curious about any of these topics, come say hi or drop us a message!

You said Sovereignty & Confidential Computing? Most databases are one breach away from full exposure - not because of bad code. But because of a structural flaw: data is stored in plaintext, and the people who operate the database can read it. We built an architecture that employs a Confidential VM/TEE enclave to encrypt data before it ever reaches Postgres. → The cloud provider cannot access the keys. The database only stores ciphertext. What you can do in the demo: • Insert a record and see the raw bytes Postgres actually stores • Search the encrypted database - postgres never sees the plaintext • Verify a live hardware attestation proving the code is unmodified → 🔗 Link in comments to try it ⬇️ If you're building systems that handle PII, financial data, or health records and want to discuss the architecture: reach out! #ConfidentialComputing #DataPrivacy #CyberSecurity #ZeroTrust #TEE #IntelTDX #MPC #KMS

 Your Mac has been running for years. When did you last audit it?  We just open sourced a hands-on security hardening toolkit for macOS — built for developers with long-lived daily-driver Macs.  7-phase security audit, malware & persistence hunting, supply chain pkgs  (npm/pip/Go/Rust), browser hardening, TCC permissions, SSH hardening, Brew cleanup. All transparent shell commands, no paid tools. ➡️ URL: https://lnkd.in/dE5_D6PW  #macOS #infosec  #hardening #opensource #supplychainsecurity

🚨 ONE leaked private key = $1.46B stolen from Bybit. We at @Katvio.com explored a solution that makes such breaches extremely difficult. 💡 What if private keys never existed in one place? We just launched a live demo of a Threshold MPC Signing Solana Oracle - a revolutionary approach to securing blockchain private keys using Multi-Party Computation (MPC) and Distributed Key Generation (DKG). 🔐 How it works: • Private key is NEVER generated in full - only cryptographic shares exist • 3-of-4 nodes must collaborate to sign transactions • No single point of failure - 1 node can be compromised without risk 🎯 Perfect for: → DeFi protocols managing treasuries → Cross-chain bridges securing assets → Any non-crypto app where single key compromise = game over 🛡️ Benefits over traditional KMS/HSMs: → Even the most secure HSMs store complete private keys in one device. Our MPC approach eliminates this single point of failure entirely - no complete key exists anywhere, making extraction mathematically impossible. 👉 Try the live demo: https://lnkd.in/eXUhJzaE (solution is not prod-ready yet) --- #Blockchain #Cryptography #MPC #DeFi #Security #Solana #Innovation #Web3 #CyberSecurity #DistributedSystems #ThresholdCryptography #PrivateKeyManagement #Oracle #SmartContracts #FinTech #EnterpriseSecurity #HSM #KeyManagement #CryptoSecurity #DistributedLedger #DecentralizedFinance #TechInnovation #SoftwareEngineering #InfoSec #DataProtection #ZeroTrust #CryptographicProtocols #SecureComputing #DistributedTrust #FaultTolerance

🔒 Building Truly Secure Hardware from Scratch We cale across an interesting blog post about the Trustless TEE Initiative - they're taking a completely different approach to secure computing by building the hardware from the ground up instead of trying to add security to existing chips. The problem with current solutions like Intel SGX? They're basically security features bolted onto hardware that wasn't designed with security as the foundation. TTEE wants to change that by creating new chips. Why this matters: Think about healthcare AI training on sensitive patient data across multiple hospitals, or law firms needing to process confidential legal documents in the cloud. Current TEEs just aren't robust enough for these scenarios - they're vulnerable to sophisticated physical attacks and supply chain compromises. What caught our attention is their approach using Physical Unclonable Functions (PUFs) - essentially chips that generate unique cryptographic keys from their own manufacturing variations and self-destruct if tampered with. Combined with advanced masking techniques, this could finally enable truly confidential computing where you don't have to trust the cloud provider or even the hardware vendor. They're launching three major projects over the next 3-4 years with significant funding. If successful, this could be the foundation for privacy-preserving AI, secure multi-party computation, and confidential smart contracts that actually work at scale. Definitely worth a read if you're thinking about the future of privacy in computing: https://lnkd.in/eJ9XEk_A #ConfidentialComputing #HardwareSecurity #PrivacyTech #AI
