| Abstract(in English) | When implementing advanced automotive services in cooperation with external data centers, it is very important to ensure information security. If a relatively powerless electronic control unit, called "Client ECU", on a motor vehicle should verify that a received digitally signed message was really sent from an external legitimate creator, it may be effective to utilize the technique called Implicit Asking, or Server-Aided Computation, for accelerating the process of signature verification by the computational resources offered by a relatively powerful ECU, called "Server ECU" on the same vehicle. This article describes a protocol which securely provides such a scenario and examines its expected efficiency with a simple provisional implementation for the case of elliptic curve digital signature algorithm ECDSA. |
