Abstract: A computer with data (the “source”) establishes communication channels to other computers with available computing resources (the “workers”). The computers exchange information to negotiate alternative sets of encryption techniques and security settings. The source calculates a response by negotiating a data reduction scheme that is applied to form heterogeneous data payloads.

Security-relevant parameters of the invoked encryption schemes are varied to achieve a negotiated optimal data reduction scheme. Candidate reduction schemes to apply to the user data are negotiated based on then-current communication bandwidth availability and/or computer processing resources at the source and/or at the workers.
