Overlay for communication anonymity and privacy in a computer network

A computing device comprising:

• memory;
• and
• processing circuitry operably coupled to the memory and configured to:
• periodically receive, from a broadcasting overlay that includes a dynamic topology of a plurality of nodes in a network, an announcement from a plurality of services at a plurality of servers connected to the broadcasting overlay, wherein the announcement indicates a plurality of roles associated with the plurality of services and information associated with a plurality of encryption keys that are associated with the plurality of services;
• determine, based at least in part on the announcement, a service associated with a specified role;
• encrypt, using an encryption key associated with the service that is derived from at least the information associated with the plurality of encryption keys as indicated by the announcement, a message to be sent to the service to generate an encrypted message;
• and
• send the encrypted message to one or more of the plurality of nodes to enable the broadcasting overlay to perform best effort broadcasting of the encrypted message to propagate the encrypted message throughout the broadcasting overlay to the service.

A computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• periodically receive, from a broadcasting overlay that includes a dynamic topology of a plurality of nodes in a network, an announcement from a plurality of services at a plurality of servers connected to the broadcasting overlay, wherein the announcement indicates a plurality of roles associated with the plurality of services and information associated with a plurality of encryption keys that are associated with the plurality of services;
• determine, based at least in part on the announcement, a service associated with a specified role;
• encrypt, using an encryption key associated with the service that is derived from at least the information associated with the plurality of encryption keys as indicated by the announcement, a message to be sent to the service to generate an encrypted message;
• and
• send the encrypted message to one or more of the plurality of nodes to enable the broadcasting overlay to perform best effort broadcasting of the encrypted message to propagate the encrypted message throughout the broadcasting overlay to the service.
