   \head{An obvious approach}
   
   A simple approach would be to generate a random key for some secure (i.e.,
-  IND-CCA) symmetric scheme, encrypt the message under that key, and, encrypt
-  the key under the recipient's public key (using some IND-CCA2 public-key
-  scheme).

   This is obviously secure.  But the security results for most public-key
   schemes are less than encouraging: the reductions, even for OAEP+, are
