Trust-Aware Adaptive Disclosure for Inference Privacy Preservation in Multi-Agent Networks
Researchers propose a trust-aware privacy framework for multi-agent systems that adapts message disclosure to reduce goal inference attacks.
The cs.CR paper addresses privacy-preserving consensus in networked multi-agent systems where observing adversaries attempt to infer each agent's hidden goal from its messages. A Trust-Aware Privacy Control framework uses a trust-dependent stochastic policy to adapt information release, trading off consensus performance and privacy. Experiments show reduced adversarial goal inference accuracy versus representative baselines while maintaining competitive consensus utility, with relevance to deployments such as healthcare management and smart grids.

Decentralized network congestion control for DAG-based distributed ledger system
Researchers propose node-specific variable proof-of-work to curb transaction spamming in DAG-based distributed ledgers, proving a Nash equilibrium enforces prescribed node behavior.
The paper proposes a variable, behavior-based node-specific proof-of-work model for DAG-based distributed ledger networks, where congestion is mainly driven by transaction spamming rather than user growth or token launches. The model grants equal opportunity to stakeholders regardless of computational resources and penalizes nodes issuing more than a prescribed number of transactions. System behavior is modeled as a non-cooperative game over finite network resources, and the authors prove existence of a Nash equilibrium enforcing the prescribed behavior.

AI is Working in the SOC. So Why are Security Executives More Worried Than Ever?
An Omdia survey of 500 security leaders commissioned by Rapid7 reports 97% positive AI outcomes in the SOC despite heightened executive concerns.
Omdia, commissioned by Rapid7, surveyed 500 security professionals and found 97% reporting positive outcomes from AI in security operations. 98% said AI reduces alert fatigue and 95% said it helps address staffing shortages. Despite this consensus, the report highlights a growing confidence gap and elevated concerns among security executives about where operations are headed.
