  • Not Spacy but love the Podcsdt

    I listen to the first half of this podcast every weeknight. I am not in the space industry and know little about it but I find the news updates fascinating. I feel like I’m learning and I had no idea of the rich news about space there is. Sometimes I listen to second half of the show but not always. A lot of that is a little “in the weeds” for me.

Talking Points

Recent interactions between the hosts and their guests.

When hackers control the clock.
Q: What practical steps can practitioners take to harden systems against timing attacks?
Use multiple, independent time sources, cross-verify time across sources, monitor for unexpected time drifts, and design systems to handle time as an input with integrity checks and fail-safes.
When hackers control the clock.
Q: Sure. Well, at a really high level, what is the central thesis of your piece on time as an input?
Time is a trusted input that many systems assume to be correct; manipulating it can produce significant security and reliability impacts across software, networks, and control systems.
Building a secure space internet.
Q: What are you hoping to learn from the upcoming demo mission?
The demo will validate the space fabric in an actual mission, ensuring cryptographic operations remain robust under radiation and temperature, confirming the hardware-software stack can survive space conditions, and verifying end-to-end attestations and data provenance in a real environment.
Building a secure space internet.
Q: Tell me a bit about how the key signing works with your solution.
Public keys are shared openly, but private keys are generated and stored in hardware-secured elements on the satellite. This enables on-board key generation, cryptographic signing, and attestation of the software stack, providing verifiable proofs from hardware up through the application layer.
Building a secure space internet.
Q: Yeah, okay. So I'm going to ask if you can give me sort of a comparison to typically how payloads would be run right now, just so we can contrast with what you all are building.
The current setup largely treats each payload as a single-user silo, limiting sharing and collaboration due to trust and security concerns. Space Fabric fundamentally changes this by enabling secure, multi-tenant workloads on the same satellite without requiring mutual trust, thereby lowering barriers to entry and reducing shared-cost frictions.
