When using authentication based on cryptography, an attacker listening to the network gains no information that would enable it to falsely claim another's identity. Kerberos is the most commonly used example of this type of authentication technology. The authors concentrate on authentication for real-time, interactive services that are offered on computer networks. They use the term real-time loosely to mean that a client process is waiting for a response to a query or command so that it can…

IAuth: An authentication system for Internet applications
  • Suan-Suan Chew, K.L. Ng, C. Chee
  • Computer Science
    Proceedings Twenty-First Annual International Computer Software and Applications Conference (COMPSAC'97)
  • 1997
TLDR
IAuth is designed, which provides secure distribution of cryptographic keys while establishing authenticity between a user and a Web-based application, and there is no need for a user to possess a cryptographic key if the application requires data encryption or digital signing.
Implementation of Authentication and Transaction Security based on Kerberos
  • R. Arora
  • Computer Science, Mathematics
  • 2011
TLDR
This project tried to implement authentication and transaction security in a Network using Kerberos, embedded with Authentication Server application and used to derive a 64 bit key from user's password.
Kerberos Active Directory for HP Thin Clients
TLDR
KAD is a protocol for client, server and a third party user, to perform security verifications for users and services, and Kerberos Active Directory security protocol is used to authenticate Thin Client users.
ENHANCED KERBEROS AUTHENTICATION FOR DISTRIBUTED ENVIRONMENT
TLDR
The need for an additional Session Key and a nonce to be used between the Authentication Server (AS) and Client i.e. Alice helps to make the security stronger and Kerberos environment to prevent such attacks.
Security management in Kerberos V5 for GSM network
  • M. Jaiganesh, B. Ramdoss
  • Computer Science

  • 2008
TLDR
This application aims at using Kerberos V5 to secure the communication between a J2Me MIDlet communicating over the GPRS, and a Banking Transaction Server.
Authentication over Internet Protocol
TLDR
A concept of user authentication in IP communication providing the receiver with the possibility to determine sender՚s identity at the Internet layer level provides both the capability of defence against DoS attacks and possibility of utilizing the presented model over existing Internet network, which is directly responsible for transmission.
Kerberos Style Authentication and Authorization through CTES Model for Distributed Systems
TLDR
An authentication and authorization model for distributed systems and an improvement over Kerberos protocol to authenticate the users and to access the services and resources that offsets certain limitations of KerberOS are described.
A new pre-authentication protocol in Kerberos 5: biometric authentication
TLDR
The initial authentication exchange in Kerberos 5 is modified by using biometric data and asymmetric cryptography to create a new preauthentication protocol in order to make Kerbero 5 more secure.
Performance analysis of the Kerberos protocol in a distributed environment
TLDR
It is concluded that improved throughput and delay characteristics can be achieved by using efficient implementations of the Kerberos protocol, together with multiple sessions for each access to the kerberos server.

TLDR
Kehne, Schonwalder, and Langendorfer have proposed a nonce-based protocol for multiple authentications that they claim improves upon the Kerberos protocol because it does not depend on the presence of synchronized clocks.

Timestamps in key distribution protocols
TLDR
It is shown that key distribution protocols with timestamps prevent replays of compromised keys and have the additional benefit of replacing a two-step handshake.
