Digital signature standard

“

- [Instructor] The Digital Signature Standard is a US federal government standard for appropriate digital signature algorithms. The standard is published by the National Institute for Standards and Technology, NIST, and the current version of the standard came out in 2013. It's published as Federal Information Processing Standard or FIPS 186-4. Let's take a quick look at some of the contents of this 100-plus page document. As you can see, it contains great detail on the acceptable implementations of digital signatures in the federal government. What you need to know about the Digital Signature Standard is that it supports three different digital signature algorithms for use in US government applications. The first is the Digital Signature Algorithm or DSA. DSA is an algorithm described within FIPS 186-4 and it's very closely related to the ElGamal algorithm. The second endorsed algorithm is the Rivest-Shamir-Adelman or RSA…
