Secure Logging for Irrefutable Administration

This paper presents a method that allows for securely saving a temporal sequence of data (log lines) in a file. Log lines are signed by an authority, and are thus unalterable without detection. Data is also encrypted in the file, and may be accessed with the granularity of a single log line with the possession of a decryption key. Also, it is possible that for some lines data must be accessed by a group of cooperating users.
