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:
“The fact is, the public make use of the classics of a country as a means of checking the progress of Art. They degrade the classics into authorities. They use them as bludgeons for preventing the free expression of Beauty in new forms.”
—Oscar Wilde (18541900)
“Leadership does not always wear the harness of compromise. Once and again one of those great influences which we call a Cause arises in the midst of a nation. Men of strenuous minds and high ideals come forward.... The attacks they sustain are more cruel than the collision of arms.... Friends desert and despise them.... They stand alone and oftentimes are made bitter by their isolation.... They are doing nothing less than defy public opinion, and shall they convert it by blows. Yes.”
—Woodrow Wilson (18561924)
