Deterministic encryption — A deterministic encryption scheme (as opposed to a probabilistic encryption scheme) is a cryptosystem which always produces the same ciphertext for a given plaintext and key, even over separate executions of the encryption algorithm. Examples of… … Wikipedia
Deniable encryption — In cryptography and steganography, deniable encryption is encryption that allows its users to convincingly deny that the data is encrypted, or that they are able to decrypt it[citation needed]. Such convincing denials may or may not be genuine.… … Wikipedia
Chosen-plaintext attack — A chosen plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker has the capability to choose arbitrary plaintexts to be encrypted and obtain the corresponding ciphertexts. The goal of the attack is to gain… … Wikipedia
One-way function — Unsolved problems in computer science Do one way functions exist? In computer science, a one way function is a function that is easy to compute on every input, but hard to invert given the image of a random input. Here easy and hard are to be… … Wikipedia
Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… … Wikipedia
RSA — In cryptography, RSA is an algorithm for public key cryptography. It is the first algorithm known to be suitable for signing as well as encryption, and one of the first great advances in public key cryptography. RSA is widely used in electronic… … Wikipedia
Coppersmith's Attack — describes a class of attacks on the public key cryptosystem RSA based on Coppersmith s theorem (see below). The public key in the RSA system is a tuple of integers (N,e), where N is the product of two primes p and q. The secret key is given by an … Wikipedia
Хандшух, Хелен — Хелен Хандшух (англ. Helena Handschuh) криптограф. Наиболее известная разработка симметричный блочный криптоалгоритм SHACAL. Помимо этого принимала участие в создании блочного шифра Universal Encryption Standard. С 2009 года… … Википедия
Personal health record — A personal health record or PHR is typically a health record that is initiated and maintained by an individual. An ideal PHR would provide a complete and accurate summary of the health and medical history of an individual by gathering data from… … Wikipedia
