This Algorithm is used to exchange the secret /symmetric key between sender and receiver. This exchange of key can be done with the help of public key and private key step 1 Assume prime number p step 2 Select a such that a is primitive root of p and a less than p step 3 Assume XA private key of user A step 4 Calculate YA public key of user A with the help of formula step 5 Assume XB private key of user B step 6 Calculate YB public key of user B with the help of formula step 7 Generate K secret Key using YB and XA with the help of formula at Sender side. step 8 Generate K secret Key using YA and XB with the help of formula at Receiver side.

In this video tutorial we will see learn how to generate Huffmans coding tree and perform the huffmans coding algorithm to encode each character using a unique binary string. We will draw the huffmans coding tree structure, assign uniqque binary values to charachters based on their frequencies or weights. Following is the question that we are going to solve: Q) Given a string AAAABBCD, Generate the Huffman code tree? Show weight order? also calculate how many bits are required to transmit the entire string?

Data compression is a ubiquitous aspect of modern computing, but not necessarily well-understood or optimally implemented. This talk will cover fundamental compression concepts that every software engineer working with the storage or transmission of data should understand. We will explore the inner workings of several popular compression algorithms and how these algorithms work for different types of data, including situations where compressing data might not actually be beneficial. * This talk description can be compressed by 46%, from 569 bytes to 309 bytes. About the Speaker: Andrew Olson is an architect on the Big Data Platform team, where he helps design and build frameworks for Cerner's cloud-based solutions using open source projects such as HBase, Crunch, Storm, and Kafka. After graduating from Iowa State University in 2001, Andrew joined Cerner as a software engineer on the team that is now known as Millennium Foundations. An avid soccer fan, you can find him in the South Stand at most home Sporting KC games. This talk was given at DevCon, Cerner's internal engineering conference.
