Adaptive chosen-ciphertext attack: Encyclopedia II - Adaptive chosen-ciphertext attack - Practical attacksAdaptive-chosen-ciphertext attacks were largely considered to be a theoretical concern until 1998, when Daniel Bleichenbacher of Bell Laboratories demonstrated a practical attack against systems using RSA encryption in concert with the PKCS #1 v1 encoding function, including a version of the Secure Socket Layer (SSL) Protocol used by thousands of web servers at the time.
The Bleichenbacher attacks took advantage of flaws within the PKCS #1 function to gradually reveal the content of an RSA encrypted message. Doing this requires sendin ...
