PRISM: PRivacy-Preserving Intrusion-Resilient Secure Multiparty-Computation-Based Messaging Overlay
·
- Applied
- protocol
Research question
What does the paper try to establish?
Can a messaging overlay combine privacy-preserving secure multiparty computation with continued operation or recovery despite compromised infrastructure?
Central answer
What is the proposed answer?
The title and project record establish that PRISM targets privacy-preserving, intrusion-resilient messaging using MPC. No public manuscript was located, so the overlay architecture, protocol messages, anonymity and resilience definitions, compromise threshold, proof, implementation, and evaluation remain unverified.
Evidence profile
Six dimensions, kept separate
The chart summarizes documented evidence and process. It is not a correctness probability, confidence score, or ranking, and no composite score is calculated.
LowMediumHighN/A = not assessed
A smaller value means less documented support for that dimension, not that the paper is false or unimportant.
- Epistemic evidence Low
-
The title and project record establish objectives and lineage, but no manuscript, security definition, proof, protocol specification, implementation, or evaluation was located.
Author-site paper metadata PRISM project provenance Documented full-text search gap - Auditability Low
-
No paper-specific official publication record, public archive, or author-hosted copy was located; full-text assumptions, evidence, and version identity cannot be audited from this map.
Documented full-text search gap - Production provenance Medium
-
Named authorship, ongoing-work status, and documented project lineage provide baseline human and lifecycle provenance. Contributor roles, manuscript revisions, AI or tool use, and artifact lineage remain unaudited.
Author-site paper metadata PRISM project provenance - External scrutiny Low
-
The item is ongoing work. DARPA program context is not a completed paper review or independent technical validation.
Author-site paper metadata PRISM project provenance - Reception Low
-
The dated exact-title search located 0 paper citations. Under the author-defined rule, 0–8 located citations is Low, 9–10 is Medium, and 11 or more is High; project and award pages are not citations.
Dated exact-title citation search - Contribution significance Not assessed
-
The objectives are potentially important, but novelty, achieved guarantees, and impact cannot be assessed from project and title metadata.

title inferredCan a messaging overlay hide sensitive communication relationships or content while continuing to provide useful service despite compromised components?
Author-site paper metadata -
objective Privacy-preserving messaging
term present definition unavailablePrivacy is an explicit design objective in the title. The protected objects—sender, receiver, relationship, message content, membership, metadata, or traffic patterns—and the anonymity game are not stated in the located sources.
Author-site paper metadata Documented full-text search gap -
objective Intrusion resilience
term present definition unavailableIntrusion resilience is explicit in the title, but compromise thresholds, proactive recovery, state refresh, availability target, detection assumptions, and recovery semantics are unavailable.
Author-site paper metadata Documented full-text search gap -
method MPC-based design
method named details unavailableSecure multiparty computation is named as a design basis. The computed functionality, participating roles, corruption model, setup, chosen MPC protocol, and online costs are not publicly specified.
Author-site paper metadata Documented full-text search gap -
protocol Messaging-overlay protocol
classified but not publicly specifiedThe curated taxonomy classifies the work as a protocol, while the title identifies a messaging overlay. No roles, message flow, state machine, cryptographic subprotocols, or failure handling can be extracted without the manuscript.

provenance DARPA RACE project lineage
documented project contextThe author-site projects page records PRISM as a 2019–2023 DARPA RACE effort led by Karim Eldefrawy. This connects the work to a funded research program but does not validate paper-level claims.
