Why Encryption and Security is Important for Computers and Email

Encryption and Security is Important

Classical Encryption Techniques

• Classical Encryption Techniques: Lecture Notes (PDF): Learn more about the building blocks of classical encryption techniques along with helpful definitions and lots of examples.
• Explanation of Classical Encryption Techniques (PDF): Several different techniques are thoroughly covered in this presentation, including substitution, transposition, and product ciphers.
• A Review on Classical and Modern Encryption Techniques (PDF): Classical and modern encryption techniques are investigated and then compared here.

Finite Fields

• Introduction to Finite Fields and Their Applications (PDF): Starting with algebraic equations, this paper touches on how finite fields work and how they can be used in everyday life.
• Efficient Software Implementation of Finite Fields With Applications to Cryptography (PDF): This paper explains how finite fields can be incorporated into computer technology, with the end result being added security.
• Finite Fields and Cryptology (PDF): Featured in the Computer Science Journal of Moldova, this paper seeks to discuss large finite fields in relation to cryptographic schemes.

Advanced Encryption Standard

• National Institute of Standards and Technology: Advance Encryption Standard (PDF): Listed are the expectations for certain government departments that work with sensitive material that needs cryptographic protection.
• 128-Bit AES Decryption (PDF) This document provides more than just an explanation of the Advanced Encryption Standard. It also describes different types of controllers and instances of AES in both hardware and software design.

Confidentiality Using Symmetric Encryption

• Encryption 101 (PDF): Take a look at this presentation that demonstrates how encryption plays an important role in information security and privacy.
• Secure Communication Using Symmetric and Asymmetric Cryptographic Techniques (PDF): This paper describes how to properly send transmissions of information using a satellite while ensuring that it is protected from any type of security threat.
• A Review on Securing Distributed Systems Using Symmetric Key Cryptograpy (PDF): DES and AES, two popular symmetric key cryptography algorithms, are looked at in depth, evaluated, and compared to one another here.

Number Theory and Hash Algorithms

• Euler and His Contribution to Number Theory (PDF): Sometimes, in order to completely understand an idea, it helps to know more about the people involved in its creation and evolution.
• Hashing Algorithms (PDF): In addition to an explanation of "hashing," this presentation serves to provide information on the type of hashing, how it works, and what implementation looks like.
• Does Hashing Make Data "Anonymous"? In addition to providing a clearer explanation of what it means to be anonymous when it comes to data, the page also allows several people working for the Federal Trade Commission to weigh in with their opinions on the matter.

Authentication Applications

• Kerberos: A Network Authentication Protocol: This page gives a detailed description of what Kerberos is and how it works as a solution to network security problems.
• Federal Financial Institutions Examination Council's Authentication in an Internet Banking Environment (PDF): Financial institutions usually have real concerns about security. This document serves to explain how agencies need to use more than one type of authentication application in order to give people access to their website and services.

Electronic Mail Security

• Security Controls Over the FDIC's Electronic Mail Infrastructure (PDF): While some security was already in place, the FDIC sought to add even more elements of security to protect information sent over email.
• Email Security: An Overview of Threats and Safeguards: In order to protect emails, it is important to understand what threats are out there and what can be done to prevent a breach.
• Securing Email: This paper discusses encryption and decryption in relation to email security, current threats, and methods for creating secure emails.

IP Security and Web Security

• A Security Architecture for the Internet Protocol (PDF): This paper discusses the implementation of security when it comes to the Internet Protocol layer and discusses the three components involved in its implementation.
• Internet Protocol Version 6: Federal Agencies Need to Plan for Transition and Manage Security Risks (PDF): The U.S. Government Accountability Office explains how different agencies need to make the change over to a new version of IP while taking a closer look at the associated risks of lack of security.

Firewalls

• A History and Survey of Network Firewalls (PDF): While firewalls offer network security, there is a lot that goes into implementing them and creating filtering rules.
• Network Communication and Firewalls: This chapter explains what a firewall is, what it does, and how it filters the flow of traffic through a network.
• Understanding Firewalls and Their Uses: This page looks to examine several different types of firewalls and how they provide an extra layer of security.
