  *) Nadhem Alfardan and Kenny Paterson have discovered an extension

     of the Vaudenay padding oracle attack on CBC mode encryption

     which enables an efficient plaintext recovery attack against

     the OpenSSL implementation of DTLS. Their attack exploits timing

     differences arising during decryption processing. A research

     paper describing this attack can be found at:
