FIPS PUB 186-4 Digital Signature Standard (DSS): July 2013

by National Institute of Standards and Technology

July 2013 This Standard specifies a suite of algorithms that can be used to generate a digital signature. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature as evidence in demonstrating to a third party that the signature was, in fact, generated by the claimed signatory. This is known as non-repudiation, since the signatory cannot easily repudiate the signature at a later time. Why buy an eBook when you can download a PDF for free? First you gotta find it and make sure it’s the latest version, not always easy. It’s much more cost-effective to just order the latest version from Amazon.com Anyone that has worked with this document knows how difficult it is to search to find that one bit of critical information. You could pull out a huge binder and flip thru pages endlessly. Not only is it time consuming, but it is exhausting lugging around a huge binder. This book is more than 135 pages long, so printing that out on paper is out of the question. ePublishing changes all that. Yes, the book is available as a PDF file, but how easy is it to navigate a large PDF document on a mobile device? Do you really want to search a 135-page PDF document manually? Load this copy onto your Kindle, iPad, Android Tablet, Nook, or iPhone (download the FREE kindle App from the APP Store) and you have an easily searchable copy. We recommend the Kindle. It’s inexpensive, has long battery life and can hold a lot of documents. Unlike a PDF file, most devices will allow you to easily navigate this ePub version to any Chapter. Note that there is a distinction between a Table of Contents and “Page Navigation”. Page Navigation refers to a different sort of Table of Contents. Not one appearing as a page in the book, but one that shows up on the device itself when the reader accesses the navigation feature. Readers can click on a navigation link to jump to a Chapter or Subchapter. Once there, most devices allow you to “pinch and zoom” in or out to easily read the text. (Unfortunately, downloading the free sample file at Amazon.com does not include this feature. You have to buy a copy to get that functionality, but as inexpensive as this is, it’s worth it.) We also print a slick bound copy with large text in 8 ½ by 11-inch format. This book includes original commentary which is copyright material. 4th Watch Publishing Co. is a Service Disabled Veteran Owned Small Business (SDVOSB) and is not affiliated with the National Institute of Standards and Technology.
