Hello Thomas !

Maybe I misunderstood the question at all. I try to begin from the
very start:
A sends a message to B. A uses the public key of B (pKb) to encrypt
the message and his secret key to sign it (sKa).
Now B has to use her secret key (sKb) to decrypt the message and the
public key of A to verify the signature (pKa).
Even if B doews not have the senders public key, in our example pKa,
she would be able to decrypt the message. She wouldn't be able to
verify the signature but she could reveal the plaintext message from
the ciphertext.
I assume you are Thomas, who speaks German?? If so, go to
www.pro-privacy.de, Inhaltsverzeichnis, Schl�sselerzeugung and click
on the first "RSA". We tried to give a practical examole of the
algorithms RSA, Diffie-Hellmann and ElGamal.
Did I get your question right??
