A capture protection server protects a cryptographic key on a device that may be captured by authenticating the user of the device (e.g., by password) before permitting the key to be used. Delegation from one capture protection server to another enables the new server to perform this capture protection function for the device. Delegation, however, opens the system to new vulnerabilities, including difficulties in limiting online password-guessing attacks and in disabling a device that has been stolen by an attacker who knows the password. Here we propose a lightweight protocol for coordinating capture protection servers that eliminates these vulnerabilities. We also report on the implementation of our protocol in a JCA-compliant cryptographic service provider, and ramifications of the JCA interfaces for our approach.
