Syn: Adversary, Enemy, Opponent, Antagonist.
Usage: Enemy is the only one of these words which necessarily implies a state of personal hostility. Men may be adversaries, antagonists, or opponents to each other in certain respects, and yet have no feelings of general animosity. An adversary may be simply one who is placed for a time in a hostile position, as in a lawsuit, an argument, in chess playing, or at fence. An opponent is one who is ranged against another (perhaps passively) on the opposing side; as a political opponent, an opponent in debate. An antagonist is one who struggles against another with active effort, either in a literal fight or in verbal debate.

The Adversary is a fictional character, a demonic supervillain appearing in American comic books published by Marvel Comics.
An adversary is generally considered to be a person, group, or force that opposes and/or attacks.
Adversary may also refer to:
- Satan ("adversary" in Hebrew), in Judeo-Christian religion
In cryptography, an adversary (rarely opponent, enemy) is a malicious entity whose aim is to prevent the users of the cryptosystem from achieving their goal (primarily privacy, integrity, and availability of data). An adversary's efforts might take the form of attempting to discover secret data, corrupting some of the data in the system, spoofing the identity of a message sender or receiver, or forcing system downtime.
Actual adversaries, as opposed to idealized ones, are referred to as attackers. Not surprisingly, the former term predominates in the cryptographic and the latter in the computer security literature. Eve, Mallory, Oscar and Trudy are all adversarial characters widely used in both types of texts.
This notion of an adversary helps both intuitive and formal reasoning about cryptosystems by casting security analysis of cryptosystems as a 'game' between the users and a centrally co-ordinated enemy. The notion of security of a cryptosystem is meaningful only with respect to particular attacks (usually presumed to be carried out by particular sorts of adversaries).
There are several types of adversaries depending on what capabilities or intentions they are presumed to have. Adversaries may be
- computationally bounded or unbounded (i.e. in terms of time and storage resources),
- eavesdropping or Byzantine (i.e. passively listening on or actively corrupting data in the channel),
- static or adaptive (i.e. having fixed or changing behavior),
- mobile or non-mobile (e.g. in the context of network security)
and so on. In actual security practice, the attacks assigned to such adversaries are often seen, so such notional analysis is not merely theoretical.
How successful an adversary is at breaking a system is measured by its advantage. An adversary's advantage is the difference between the adversary's probability of breaking the system and the probability that the system can be broken by simply guessing. The advantage is specified as a function of the security parameter.
