Are the thermodynamics of an AI data center in orbit efficient enough to be worth the investment? We're diving into the engineering and economics of computing in orbit panel at Silicon Valley Space Week. Our Co-founder and CTO @Filip Rezabek is joining the discussion alongside Jason Aspiotis at OwlO Cloud, Rob DeMillo at Sophia Space, Dr. Slava Turyshev @NASAJPL, and Joseph Yaffe at @CowboySpaceCorp, moderated by Janna Lewis @_Rocketdyne. "Orbital Data Centers: Investable infrastructure or thermodynamic bet?" ➤ Tue, Oct 27 | 12:15 PM – 1:00 PM 📍 Hahn Auditorium Attending Silicon Valley Space Week? Let’s connect! Find us at booth 14 🛰️

SpaceComputer key management service (KMS) is live in beta to start testing in your security flow today. Current capabilities include: ✓ Secret key generation and storage ✓ AWS KMS style API ✓ Custom policies ✓ Multi-tenancy ✓ AI workflow support Test out KMS, available by SDK and CLI → accounts.spacecomputer.io Follow for upcoming features releases related to AI and post quantum capabilities!

During #WorldSpaceWeek, we’re celebrating a year of progress and momentum at SpaceComputer 🛰️ From launching our key management service this week, to preparing for our upcoming launches in 2027, our team at SpaceComputer is working hard to build compute and security capabilities for the next generation of space internet applications. Behind every milestone we reach is an incredible team pushing SpaceComputer forward! 🚀

We’re excited to announce SpaceComputer Key Management Service is live in public beta. KMS acts as a verifiable control plane for cloud services, financial systems, and agentic applications rely on cryptographic keys to authorize high-value actions like signing, decrypting, and provisioning. Our priority is to build a KMS domain strongly isolated, attestable, policy-controlled, cryptographically-agile and auditable. Starting today, our KMS capabilities are available by SDK and CLI: ✓ Secret key generation and storage ✓ AWS KMS style API ✓ Custom policies ✓ Multi-tenancy ✓ AI workflow support More updates are rolling out in the coming weeks, including TEE enablement, attestable execution, threshold cryptography, and PQC capabilities.

Giving an AI agent its own private key is one of the riskiest security decisions you can make right now. A private key allows software to sign transactions for you, and researchers have already tricked AI agents into signing transfers to wallets the researchers controlled. A key management service (KMS) keeps keys locked away and still allows agents to use them, without ever having full access to the key itself. There's 3 critical reasons your agents need a KMS that is actually secure👇 1. A tricked agent can't leak the key if it never has full access to it 2. Limits live at the key level, so when you set a limit like "never send more than $500" the agent cannot bypass this limit 3. Hardware-isolated environments (like TEEs) let you verify where signing happens instead of trusting a server As agents get more capable, a trusted KMS is how you decide what they're actually allowed to do. We see this as critical infrastructure to the future of the space internet. More to share on this soon 👀

Post Quantum Cryptography (PQC) is critical infrastructure for space technologies. And this is a much deeper conversation than just preparing for the inevitability of quantum computers breaking classic cryptographic encryption. We need to build adaptable, software-enabled post-quantum migration solutions for spacecrafts that work with data in any capacity. At SpaceComputer, PQC readiness and migration is a top priority amongst our cybersecurity solutions. Subscribe & watch the full video on YouTube: youtu.be/oa4zc0JiwH0

Post-quantum migration is fundamentally a key management problem. You can’t upgrade key security if you can’t find the keys. A key management service (KMS) centralizes key generation, storage, access control, rotation, and audit, so keys live in one hardened place, like a trusted execution environment (TEE). That's security you need today. Post quantum cryptography (PQC) is security for the future where quantum computers will eventually break public key encryption. These threats are relevant today. Harvest now, decrypt later attacks collect encrypted data today to break it once quantum machines are strong enough. So why do you need both? When every key lives in a KMS and you swap in quantum-resistant algorithms, every key inherits the upgrade. The KMS becomes your layer of cryptographic agility. A KMS also automates the mechanics of generating new keys, re-encrypting data, and key rotation and retirement across your stack. It also absorbs the friction of PQC's larger keys and signatures so your applications stay fast. With quantum computing still on the horizon, and KMS options available from every cloud provider, why is SpaceComputer building a post-quantum agile platform? One simple reason: a satellite launched today must be ready for the next 5-10 years. You can't add hardware in orbit (for obvious reasons), so crypto-agility must be built in before launch. Our KMS will anchor keys in attested TEEs, non-exportable by design: they can be used but never extracted. We're starting with hardened infrastructure on Earth, eventually moving to keys born in orbit inside a satellite-based TEE, with post-quantum readiness currently in development. So we ask you: how are your security keys managed today? And if you could test a KMS built for orbit: would you? Drop a 🙋 below if you'd want early access.

Post-quantum cryptography changes the math that supports your security without changing how it works on the surface. You'll still have a private key and a public key. The algorithms are migrated within a key management service to withstand quantum computers, not just classical ones. @rezabfil breaks it down in the clip below 👇

If your satellite isn't secure at launch, it can be compromised with as little as a software-defined radio and a few software bugs. "So we have to consider the life cycle and the lifetime of the designs of the respective choices, the respective spacecrafts and make sure that there are solutions for that." That's our mission at at SpaceComputer: building secure satellite computing systems for the long term, starting at the hardware and software level.
