One New Type Fail-Stop Signature Schemes

In later chapters, several digital signature schemes will be presented or mentioned where at least the signer is information-theoretically secure, and sometimes even the recipient, too. The main point in overcoming the impossibility proof was to notice that digital signature schemes may have structures other than that described in [DiHe76] and made precise in the GMR definition (see Sections 2.3, 2.6). 

For technical reasons, key generation is also modified, see Section 6.1.2.
