Authentication methods

Listening has been paid much attention to by language researchers and teachers. Many researchers have been conducted on how to teach and learn listening skills effectively. However, as far as the writers have investigated, most of the researches focus largely on methods of teaching and learning rather than on exploiting new sources of authentic materials for teachers to make use of.

In this work, one of the methods deploying encryption to cipher data is represented. The primary object of this project is applying Advanced Encryption Standard (AES) in communications based Orthogonal Frequency Division Multiplexing (OFDM). This article discusses the security of the method encrypting directly QAM symbols instead of input bit-stream.

Like paper-based signatures, digital signatures intend to respect a number of security assumptions. Methods of digital signature apposed by a single user have been defined and are widely used. But is it sufficient? What if a legal document requires witnesses and notarization, or a contract needs the signatures of several officers?This paper will first show the basics to understand digital signatures and how the a security properties of integrity, authentication, and non-repudiation are respected.

We have looked at protocols for distributing and establishing keys used for authentication and confidentiality But who should you give these keys to? Who should you trust? What are the rules governing when to and not to give out security credentials In this lecture, we will look at the broad area of secure and trusted systems We will focus on access control models These methods are often used to abstract the requirements for a computer system But, they hold for general systems where security is a concern (e.g. networks, computers, companies…) ...

To use data encryption algorithms in network communications, all parities must first agree on using the same secret keys Rely on couriers Set up a meeting to determine a secret key Use postal service, email service, phone service … However, these conventional methods are inflexible for network communication applications Public-key cryptography (PKC) Invented in the 1970’s Without the need of sharing prior secrets to distribute secret keys securely Can also be used for authentication

A backdoor in a computer system (or cryptosystem or algorithm) is a method of bypassing normal authentication, securing illegal remote access to a computer, obtaining access to plaintext, and so on, while attempting to remain undetected. The backdoor may take the form of an installed program (e.g., Back Orifice) or may subvert the system through a rootkit.
