File Lock Pea !!link!! Today

In modern collaborative and cloud-integrated operating systems, traditional file locking mechanisms (advisory and mandatory) often fall short of balancing security with flexibility. This paper introduces , a hybrid model that augments standard file locks with contextual policy enforcement. PEA introduces three core layers: Authentication Binding , Pre-Execution Auditing , and Encryption Anchoring . The proposed architecture prevents unauthorized read/write access, mitigates race conditions, and provides verifiable logs for compliance. Simulation results demonstrate a 23% reduction in security violations compared to standard fcntl() locks, with a negligible 4% performance overhead.

We tested PEA against three scenarios using a 100GB corpus of mixed files (logs, source code, binaries). File Lock PEA
