AKA stands for the Authentication and Key Agreement security protocol. It is a mechanism which performs authentication and session key distribution in Universal Mobile Telecommunications System (UMTS) networks. AKA is a challenge-response based mechanism that uses symmetric cryptography. AKA is typically run in a UMTS IM Services Identity Module (ISIM), which resides on a smart card like device that also provides tamper resistant storage of shared secrets.

As current authentication mechanisms evolve and as new authentication mechanisms are introduced, system entry services such as login, rlogin, and telnet must continually be customized to incorporate these changes.

With the Pluggable Authentication Module (PAM) framework, multiple authentication technologies can be added without changing any of the login services, thereby preserving existing system environments. PAM can be used to integrate login services with different authentication technologies, such as RSA, DCE, Kerberos, S/Key, and smar ....etc

Definition
Reliable user authentication is becoming an increasingly important task in the Web-enabled world. The consequences of an insecure authentication system in a corporate or enterprise environment can be catastrophic, and may include loss of confidential information, denial of service, and compromised data integrity. The value of reliable user authentication is not limited to just computer or network access. Many other applications in everyday life also require user authentication, such as banking, e- commerce, and physical access contr ....etc

Authentication and security have been major issues right from the beginning of the computer age. One of the emerging and efficient keys to security problem is Biometrics-a technology that strives towards identifying the identity of a living person based on biological characteristics. Biometrics possesses many advantages over conventional user authentication processes. Because a biometric is an intrinsic property of some individual they are difficult to duplicate and impossible to share. Examples of automated biometrics include fingerprints, fac ....etc

Biometric recognition refers to the use of distinctive physiological (e.g., fingerprints, face, retina, iris) and behavioral (e.g., gait, signature) characteristics, called biometric identifiers (or simply biometrics) for automatically recognizing individuals. Perhaps all biometric identifiers are a combination of physiological and behavioral characteristics and they should not be exclusively classified into either physiological or behavioral characteristics. For example, fingerprints may be physiological in nature but the usage of the input d ....etc

Introduction

This paper explores the various techniques used to authenticate the visual data recorded by the automatic video surveillance system. Automatic video surveillance systems are used for continuous and effective monitoring and reliable control of remote and dangerous sites. Some practical issues must be taken in to account, in order to take full advantage of the potentiality of VS system. The validity of visual data acquired, processed and possibly stored by the VS system, as a proof in front of a court of law is one of such issues ....etc

CHAPTER 1
INTRODUCTION
1.1 OVERVIEW
With the increasing use of distributed systems, users often need to access multiple resources to finish a single business transaction. Traditionally, users have had to sign on to all these systems, each of which may involve different usernames and authentication requirements. With the introduction of the single sign-on technique, users can login once and be authenticated for all systems involved in a given business transaction.
PAM and PAM-aware applications reduce the complexi ....etc
