Adaptive Chosen-ciphertext Attack - Preventing Attacks

Preventing Attacks

In order to prevent adaptive-chosen-ciphertext attacks, it is necessary to use an encryption or encoding scheme that limits ciphertext malleability. A number of encoding schemes have been proposed; the most common standard for RSA encryption is Optimal Asymmetric Encryption Padding (OAEP). Unlike ad-hoc schemes such as the padding used in the early versions of PKCS#1, OAEP has been proven secure in the random oracle model. OAEP was incorporated into PKCS#1 as of version 2.0 published in 1998 as the now-recommended encoding scheme, with the older scheme still supported but not recommended for new applications.

Famous quotes containing the words preventing and/or attacks:

    If anything characterizes the cultural life of the seventies in America, it is an insistence on preventing failures of communication.
    Richard Dean Rosen (b. 1949)

    There exists, at the bottom of all abasement and misfortune, a last extreme which rebels and joins battle with the forces of law and respectability in a desperate struggle, waged partly by cunning and partly by violence, at once sick and ferocious, in which it attacks the prevailing social order with the pin-pricks of vice and the hammer-blows of crime.
    Victor Hugo (1802–1885)
