Patent ID: 11443049

Abstract:
Systems and methods described herein securely compute private data on a cloud platform. A network device in the cloud platform obtains a product or service description from a first user. The description includes a combination of public data and encrypted private data based on a first encryption key. The network device receives a query from an end device of a second user and retrieves, based on the query, the product or service description. The network device forwards the description to a trusted execution environment (TEE) instance for decryption of the encrypted private data, processing of the private data, and re-encryption of the private data with a second encryption key. The network device receives the re-encrypted private data from the TEE instance and assembles the re-encrypted private data and the public data into a query response for presentation on the end device. The network device sends, to the end device, the query response including the re-encrypted private data and the public data.
