Key Agreement Over Inter-Process Communication

Today’s computer is often infected by malwares and conventional communication channels such as inter-process (IPC) are attractive attack surface for attackers because important information user’s personal data passwords transmitted between processes over IPC. In addition, there no other protection than the access control mechanism provided underlying OS, but it not always sufficient. To improve situation, this paper proposes a key agreement protocol using network socket, which one of IPC methods. Our provides means legitimate to cryptographically communicate We use an uncertain channel secure we found that behaves due process scheduling OS. The proposed based on random number sharing messages attacker probabilistically fails obtain detection who interrupts protocol. against impersonates processes. experiment behavior actual device confirm our achieves 128-bit security in realistic execution time within 8.5 ms. best knowledge, proposal first countermeasure with cryptographic strength under reasonable assumptions.
