"WebAttack model. In cryptanalysis, attack models or attack types [1] are a classification of cryptographic attacks specifying the kind of access a cryptanalyst has to a system under attack when attempting to "break" an encrypted message (also known as ciphertext) generated by the system.

WebCryptographic computing is a technology that operates directly on cryptographically protected data so that sensitive data is never exposed. Cryptographic computing covers a broad range of privacy preserving techniques including secure multi-party computation, homomorphic encryption, privacy preserving federated learning, and searchable encryption. WebCryptographic schemes are usually based on complexity assumptions, which state that some problems, such as factorization, cannot be solved in polynomial time. Schemes that can be proven secure using only complexity assumptions are said to be secure in the standard model.
