Security issues are a core part of distributed computing systems, and are part of everyday life since they are used in web servers, email, mobile phones, bank transactions etc. Applications which send an unencrypted password over a communication channel are extremely vulnerable. In addition, the only techniques that have been applied to most systems are security properties such as secrecy and authenticity. A system usually needs to identify its legal users for providing its services therefore, there is a need to construct an authentication system in the client server model to make sure the sent message is confidential, integral, and non-repudiate and secure. The objective of this paper is to provide strong authentication for client and server applications by using secret-key cryptography and to detect any infected packets through analysis using a TCP damp sniffer. The solution consists of two main parts: authentication and virus detection. Authentication is the first part in which login process is required. The AES symmetric key encryption is used to encrypt the password to guarantee confidentiality while message digest is another way to prove the integrity checking. The results obtained in this paper consists of a non-repudiation method which can create the digital signature and virus detection, which can be done through analysis of the payload that has been captured by using Tcpdump sniffer. Finally, the cryptographic authentication system with secure file payload analyzer can be constructed successfully and will be able to detect an infected packet as well as delete it.
