Abstract:

In many democratic countries, CALEA wiretaps are used by law enforcement agencies to perform investigations and gather evidence. This paper proposes a lightweight accountable wiretapping architecture for secure auditing of existing CALEA systems. Based on publicly available wiretap reporting statistics, we conservatively estimate that our architecture can support tamper-evident logging for the US’ ongoing CALEA wiretaps using three commodity PCs.
