Tutorial: An application may require security services that maintain anonymity of users or other system entities, perhaps to preserve their privacy or hide them from attack. To hide an entity's real name, an alias may be used; for example, a financial institution may assign account numbers. Parties to transactions can thus remain relatively anonymous, but can also accept the transactions as legitimate. Real names of the parties cannot be easily determined by observers of the transactions, but an authorized third party may be able to map an alias to a real name, such as by presenting the institution with a court order. In other applications, anonymous entities may be completely untraceable.
