  • Patent number: 11909868
    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.

  • Patent number: 11860859
    Abstract: A distribution server restructures content and information published to a topic tree for more efficient and meaningful presentation to a subscribing client. To do so, the distribution server receives a request to create a topic view from a client and creates the topic view in response. The topic view includes a set of selected topics and a topic view mapping. The topic view mapping maps the topic paths for the set of selected topics to a set of reference topics at a set of reference paths. In other words, the topic view restructures the content and information by creating new branches in the topic tree. Whenever a selected topic receives an update from a publisher, the distribution server publishes the update as restructured content and information to the reference topics at the reference paths. A client subscribed to the reference path receives the update in a restructured manner.

  • Patent number: 10666738
    Abstract: To represent the indirect lifecycle binding between the validity of data for a given topic, and the presence of sessions responsible for updating the data associated with that topic, sessions may register a policy referred to herein as a “session will” against specific nodes in the topic tree maintained by a data distribution system server. A session will binds the lifecycle of the topic node to that of the registering session. When a session that is responsible for updating a particular topic is disconnected, the data distribution system server initiates actions in accordance with the session will to determine how to manage updating the topic and the sub-topics in the topic path.
