Abstract:
Disclosed is an orthogonal access control system based on cryptographic operations provided by multi-hop proxy re-encryption (PRE) that strictly enforces only authorized access to data by groups of users, scalable to large numbers of users. Scalable delegation of decryption authority can be shared with a plurality of members of a group whether those members be users or devices, and members of a group can further create sub groups and delegate decryption authority to those members, whether users or devices. Members are granted access via generation of transform keys, and membership or access can be revoked merely be deleting the transform key—no elimination of the encrypted data, regardless of its storage location, is needed.

Claim (Index 2):
The system of  claim 1 , wherein the private key for the second device is stored on a private key storage of the second device and the private key for the first group of users is stored on a private key storage of the first device.
