In cryptography, an adversary's advantage is a measure of how successfully it can attack a cryptographic algorithm, by distinguishing it from an idealized version of that type of algorithm. Note that in this context, the " adversary " is itself an algorithm and not a person .
Adversary (cryptography), a malicious entity in cryptography whose aim is to prevent the users of the cryptosystem from achieving their goal; Adversary model, in online algorithms, used to show competitiveness of randomized algorithms; Adversarial alignment, when an adversarial users constructs inputs that bypass AI alignment
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.
Intrusion kill chain for information security [1]. The cyber kill chain is the process by which perpetrators carry out cyberattacks. [2] Lockheed Martin adapted the concept of the kill chain from a military setting to information security, using it as a method for modeling intrusions on a computer network. [3]
a person employed to oversee the cleaning and security of a public building, e.g. a school. a person employed to oversee the cleaning and security of a building (UK: caretaker, especially for private residences; for schools etc. janitor is also used in the UK) jelly a fruit flavoured dessert set with gelatin (US: Jell-O (trademark))
The oblivious adversary is sometimes referred to as the weak adversary. This adversary knows the algorithm's code, but does not get to know the randomized results of the algorithm. The adaptive online adversary is sometimes called the medium adversary. This adversary must make its own decision before it is allowed to know the decision of the ...
Example scenario where communication between Alice and Bob is intercepted by Mallory. Alice and Bob are fictional characters commonly used as placeholders in discussions about cryptographic systems and protocols, [1] and in other science and engineering literature where there are several participants in a thought experiment.
Deniable encryption serves to undermine an attacker's confidence either that data is encrypted, or that the person in possession of it can decrypt it and provide the associated plaintext. In their pivotal 1996 paper, Ran Canetti , Cynthia Dwork , Moni Naor , and Rafail Ostrovsky introduced the concept of deniable encryption, a cryptographic ...
