Over the past few decades, digital communication has grown by leaps and bounds. The expanding use of the internet in our day-to-day lives has resulted in a six-fold increase in the number of internet users in the past two decades alone, leading to an evolution of technologies for home use such as Cloud Computing, Artificial Intelligence, Big Data Analytics and Machine Learning.

Today, 30% of the total business worldwide is done online, with approximately 25% of banking transactions being done exclusively from smart-phones and laptops at home or the office. Moreover, 50% of the worlds population is currently using social media as a platform for connecting with their friends and colleagues; and primary and higher education institutions are using internet-based education as a tool for enriching students knowledge and at the same time keeping track of their academic performance. Now even Government agencies are moving to internet platforms, with most of their services currently available online.

Although this huge volume of internet usage has made life easier for every individual, insecurity or loss of information continues to be a major concern. There have been many cases across the globe of breach of information or platforms leading to loss of data, money, faith and much more.

Various research scientists have done a lot of work over the past five to six decades to develop security protocols for ensuring minimization of breach of data either being stored or under one network. The history of information security has been quite long and has evolved from the era of its birth to present date. During this period millions of cryptographic algorithms have evolved, some of which have been quite successful for ensuring many secure communications across the World Wide Web.

The application of security has changed as technology has evolved from tube computing to palm (nano) computing. Presently, we have many different security protocols for various types of applications of the internet like email, web browsing, webchat, video streaming, cloud-based communication, closed group communication, banking transactions, e-commerce and many more both at network level and user end.

Security has evolved to counter many kinds of attacks like intrusion, manipulation, spoofing and so on, for which techniques like cryptography, message digest, digital signature, steganography, watermarking, time stamping, access control, etc., have been incorporated into various layers of communication, resulting in protocols like HTTP, SMTP, RTP, RTCP, FTP, UDP and many more.

The issue with these protocols is that they are not being reviewed from time to time, nor are they being compiled and compared in one place. Our aim in publishing this book is to combine the analysis and comparison of various protocols which might act as a Mobile Communication Security Protocol or Multimedia Streaming Security Protocol. Therefore, this book discusses and analyzes some of the security protocols available for communication in various application areas.

The 15 chapters of this book are well placed to illustrate the security protocols for communication. Following is a brief synopsis of each chapter:

• gives a detailed history of communication and the evolution of its protocols; and relates the evolution of security and the need for it in communication protocols.
• discusses the evolution of various information security algorithms, from basic models to complex information security algorithms currently in use.
• digs further into security algorithms by focusing on the philosophy of security by cryptostake schemes, a model for public key cryptographic techniques.
• introduces a new technique for key management of security algorithms being implemented over a communication channel.
• introduces a soft computing-based intrusion detection system with reduced false positive rate, which helps in intrusion detection in a communication channel, even if the signature of the intruder is not available.
• proposes a new simple cipher, namely recursively paired arithmetic technique (RPAT): A field-programmable gate array (FPGA)-based block cipher simulation and its cryptanalysis.
• reviews security protocols like RTP, RTMP, UDP, etc., for multimedia communication over a channel; it attempts to analyze the performance of these protocols on the basis of delay as parameter.
