Re: Davis paper revisited // separation of signed and encrypted messages into clearsigned messages

2003-08-22 18:16:56

I just want to make sure I understand this.

The problem is this:

Alice sends Bob an encrypted and signed message.

Bob decrypts the message, and then does byte-surgery to construct a
plaintext clearsigned message that the signature verifies, and anyone in the
world can read.

This is the "attack," right?
