Implementation of highly efficient Authentication and Transaction Security

چکیده
Kerberos is a network authentication protocol & is designed to provide strong authentication for client/server applications by using secret-key cryptography. Our research was aimed at enhancing the security of transactions over a network. In this paper, we used Kerberos Encryption Technique for authentication and transaction security in the network. Further, we created an Authentication Server that used to derive a 64 bit key from user’s password. This password was of arbitrary length. The generated key then was used by authentication server, to encrypt ticket granting ticket + session key. The key generated by authentication server was then used by the client at the time of transaction through the transaction server to validate an authentic transaction. However, there was an issue of crossvalidation of the ticket by the transaction server for which we included a database and encryption of all the text sent by any client to the transaction server.

A Trust Based Probabilistic Method for Efficient Correctness Verification in Database Outsourcing
Correctness verification of query results is a significant challenge in database outsourcing. Most of the proposed approaches impose high overhead, which makes them impractical in real scenarios. Probabilistic approaches are proposed in order to reduce the computation overhead pertaining to the verification process. In this paper, we use the notion of trust as the basis of our probabilistic app...

متن کاملA hybrid approach for database intrusion detection at transaction and inter-transaction levels
Nowadays, information plays an important role in organizations. Sensitive information is often stored in databases. Traditional mechanisms such as encryption, access control, and authentication cannot provide a high level of confidence. Therefore, the existence of Intrusion Detection Systems in databases is necessary. In this paper, we propose an intrusion detection system for detecting attacks...
متن کاملAn ECC-Based Mutual Authentication Scheme with One Time Signature (OTS) in Advanced Metering Infrastructure
Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication. This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...
