Abstract
An endpoint encrypts local files with a key to protect file contents. If the endpoint or processes on the endpoint becomes exposed to potentially harmful locations or resources, the key can be revoked to prevent access to encrypted files on the endpoint. In order to facilitate continued operation of the endpoint, files that are currently open can be encrypted with a second key so that the corresponding data is isolated from the other encrypted files while remaining accessible to current users.
