-\caption{The construction of a KBlock. The hashed keyword $H(K)$ is used to 
encrypt the
-data and to seed the key generator. The obtained private key $PrvH(K)$ signs 
the encrypted data, but is not otherwise used.
-Finally, the public key $PubH(K)$ is catenated to the signed data to form the 
final KBlock.}
