Cosmian

Cosmian leverages advanced cryptography and encryption technologies to provide decentralized developer tools. Its Cosmian Secure Computation is a serverless free public platform that allows users to encrypt code and sensitive data at rest, in motion, and in use, including in the cloud, big data processing chains, and data repositories with different keys. It deploys the encrypted data or code to a Cosmian secure enclave and performs computations without exposing the underlying data. It only allows authorized users to decrypt the computation results.

Cosmian’s Cloudproof Encryption API and libraries encrypt big data repositories with different keys in the same dataset. It allows users to decrypt it with a unique secret key with an access policy matching the chosen policy attributes. It allows secure data partitioning, public key encryption, attributes rotation, and data access policy backed by cryptography. The tool also provides encrypted indexing and encrypted queries to securely find and retrieve encrypted data. As of June 2022, the company had an employee headcount of 20.
