Implicit influence propagation between delegation chains without formal delegation steps

Characterize and control implicit influence propagation between concurrent delegation chains that lack explicit, DAS-signed delegation steps in SentinelAgent’s Delegation Chain Calculus, and establish mechanisms to preserve accountability and enforcement of properties P1–P7 under such interactions.

Background

While SentinelAgent’s security guarantees apply to explicit, tokenized delegation chains, the system may still be affected by indirect interactions across chains that are not represented as formal delegations.

The authors explicitly identify implicit influence propagation between chains without formal delegation steps as an unaddressed open problem, pointing to prior observations of such effects in multi-agent systems.

Remaining open problems. Collusion via side channels (analogous to covert channels in traditional access control), implicit influence propagation between chains without formal delegation steps, and Privacy Act consent modeling remain unaddressed.
