Cryptosat, a startup launching a Trusted Execution Environment in space, has released its first Cryptosim Software. Designed for developers, Cryptosim combines an API tutorial with a satellite trajectory simulation. This will enable developers to get a feel for how they can interact with software on Cryptosat’s low earth orbit (LEO) satellites once in space.
Cryptosat’s tamper-proof root-of-trust is achieved through complete device isolation by launching LEO satellites. Running code on an orbiting satellite is significantly different from running code on AWS. To reduce the learning curve, Cryptosim intends to walk developers through the process for interacting with software installed on the satellite.
The simulator UI includes a tutorial that describes the API functions supported by Cryptosat and a map that shows the satellite trajectory. There is also a JavaScript console where the user can programmatically try the API and interact with the simulated satellite to request its status, sign messages, request randomness, generate Delay-Encryption key-pairs and more.
The Cryptosim API teaches developers about the asynchronous manner in which the satellite software works. It is designed this way to account for the fact that satellites are not visible to ground stations 100% of the time.
Functions that can be called using the current build of Cryptosim include:
Public randomness (Random Beacon)
Private randomness: where a user requests random bits to be encrypted to a public key they provide in the request
Retrieving a signed timestamp: used by applications that require a trusted source of time or smart contracts that need to ensure a certain amount of time has passed in the real world
Delay encryption: where a satellite generates a cryptographic key-pair and publishes the public key. The private key is not released before a specified amount of time has passed, preventing premature decryption
Signing any data in space

Cryptosat is inviting developers to trial its API and acclimatize themselves to the capabilities of its LEO satellites. It is encouraging blockchain teams to propose new use cases for its product, over and above the multiple applications that have already been envisioned.
Using its own satellites built from the ground up, Cryptosat can guarantee that no third party has interfered with the compute environment prior to its being launched into orbit. This provides a unique guarantee that not even nation-state actors can tamper with the operations that are carried aboard the satellite.
