The thesis presents verification of biometric authentication protocols. ProVerif is used as the verification tool for verifying and analysing the protocols. The protocol are analysed in ProVerif model. Various attacks to the protocols are generated in order to verify whether the protocols hold their intended properties. We have selected three biometric authentication protocols and proposed a re...

For portable communication systems, the delegation-based authentication protocol provides efficient subsequent login authentication, data confidentiality, user privacy protection, and non-repudiation. However, in all proposed protocols, the non-repudiation of mobile users is based on an unreasonable assumption that home location registers are always trusted. To weaken this assumption and enhanc...

Kerberos is the widely deployed authentication protocol. This document gives you comparison between NTLM and Kerberos authentication. And it gives information on how Kerberos authentication plays a vital role in authentication and delegation scenarios, and the situations where Kerberos authentication should be used or may be required in solution designs. Scenarios include business intelligence ...

The amount of data that must be processed, stored, and modified rises as time passes. An enormous volume from a wide range sources stored on safe platform. Maintaining such large single computer or hard drive is impracticable. As result, the cloud ideal platform for storing any quantity data. advantage in it may accessed at device. However, security big concern. Because this, despite benefits, ...

We introduce context-aware scalable authentication (CASA) as a way of balancing security and usability for authentication. Our core idea is to combine a number of passive factors for authentication (e.g., a user’s current location) with appropriate active factors. In this paper, we provide a probabilistic framework for dynamically selecting an active authentication scheme that satisfies a secur...
