SECURE SHARED KEY ESTABLISHMENT FOR PEER TO PEER COMMUNICATIONS

摘要

Systems and methods for secure peer-to-peer communications are described. Devices registered into trusted network may be capable of establishing a shared data encryption key (DEK). In embodiments, each device may be configured to obtain a share of a data encryption key (DEKi) that can be stored locally. The shares may be shares in an M of N Secret Sharing Scheme. This may involve a network that includes an integer, N, devices, and in which M devices may share a secret (i.e. the DEK) during communications, M being an integer less than or equal to N. To obtain the entire DEK during encryption/decryption, a requesting device may send requests to M of N devices for their shares of the DEK. Once M shares are obtained, they may be used generate the DEK for encrypting/decrypting data between the devices.
