      Although cryptography is generally considered to be useful for hiding
      information or holding it confidential, cryptographic methods can also
      be used to determine whether data has been altered. Slightly more
      specialized means can also be used to provide evidence that a certain
      individual composed or verified a certain message, in the same way
      that a handwritten signature is presumed to assert a person's intent
      or agreement with respect to a contract. Properly used and supported,
      these digital signatures can be stronger and more flexible than
      physical signatures as a means of binding an identity to a document.

      Chapter one is an introduction, both to some basic concepts, and to
      the book as a whole. (The material is disjointed in places: there is
      a section entitled "Legislation" on page six and another on page
      eight, although the content is different.) The overview of
      cryptography, in chapter two, has some very weak and some very good
      points: the explanation of the four modes of DES (Data Encryption
      Standard) is much clearer than in most texts. The description is,
      however, very generic, and does not address hash or signature topics
      at all, nor does it address algorithmic and key length strength and
      weakness. Certificates are a vital part of the common digital
      signature structure, but chapter three's discussion concentrates on
      X.509 fields and request procedures, without getting into the
      underlying concepts. Data integrity is another key (sorry) concept in
      the creation of digital signatures, but while the material on
      checksums and hashing starts out well, chapter four ends in something
      of a confusing mess. Chapter five flits between real and theoretical
      systems in such a way that no valid assessment of uses and
      shortcomings is possible. A number of miscellaneous topics are listed
      in chapter six. Chapter seven looks at various business issues and
      models, generally with respect to public key infrastructure, but is
      oddly unhelpful in real world terms. Some standards are listed and
      tersely described in chapter eight. Definition sections lifted from
      various pieces of legislation are reproduced in chapter nine. Chapter
      tens lists a number of legal concepts that may have a bearing on
      digital signatures: these are more practically related to systems and
      policies in chapter eleven.

      The technical and practical aspects of this book fall far short of
      being useful either to the security professional, or to the manager
      who may need to address the topic or make decisions about systems.
      The legal sections, however, might justify, for the professional, the
      purchase of this otherwise confused work.
