While cryptographic encryption can be used as protection from unauthorized access, protection from linkability must be achieved by ensuring the anonymity or untraceability of communication. Secure electronic voting provides a case in point. A voter’s encrypted electronic vote should be untraceable, thus preserving the voter’s privacy.
