The menace of attackers over the network is unstoppable for the past two decades. The security practitioners and researchers are devising mechanisms to safeguard the network and its components, but still attackers emerge with cutting edge technologies to disturb the intention of legitimate users in the network. Thus, before devising proper defensive mechanisms against a specific attack, it is essential to understand the motive and strategies of the attackers with the proper clarity. This paper presents a virtual honeynet framework to record all the attackers’ activities and analyzes the strategies, tools, and mechanisms followed by the attacker, in a real-time manner. We analyzed the recorded attacks in our framework with respect to different parameters like protocol, ports, honeypots, and IDPS tools to understand the motive behind the attacks. This novel virtual honeynet architecture will give insight to the readers and security practitioners to understand the strategies followed by the attackers as well as the way of designing different traps to secretly follow the attackers in the road toward foolproof safeguarding mechanisms. © Springer Nature Singapore Pte Ltd 2020.

Intrusions pose a serious securing risk in a network environment. Network intrusion detection system aims to identify attacks or malicious activity in a network with a high detection rate while maintaining a low false alarm rate. Anomaly detection systems (ADS) monitor the behaviour of a system and flag significant deviations from the normal activity as anomalies. In this paper, we propose an anomaly detection method using "K-Means + C4.5", a method to cascade k-Means clustering and the C4.5 decision tree methods for classifying anomalous and normal activities in a computer network. The k-Means clustering method is first used to partition the training instances into k clusters using Euclidean distance similarity. On each cluster, representing a density region of normal or anomaly instances, we build decision trees using C4.5 decision tree algorithm. The decision tree on each cluster refines the decision boundaries by learning the subgroups within the cluster. To obtain a final conclusion we exploit the results derived from the decision tree on each cluster.

Yang-Wang-Chang proposed an improved timestamp associated password authentication scheme based on Yang-Shieh, who had earlier proposed timestamp-based remote authentication scheme using smart cards. In this paper, we propose an efficient password authentication scheme with smart card applying RSA. The proposed scheme withstands most of the attacks with minimum computational cost.

An efficient password authentication scheme for smart card

Remote user authentication is a continual problem, particularly with mobile and handheld devices such as Personal Digital Assistants (PDAs), Smartcard, Laptops. Providing user authentication for safe access of precious, private information, or personalized services, for every system is difficult User authentication is the primary line of defence for a handheld device that falls into the hands of an unauthorized individual. Password or Personal Identification Number (PIN) based authentication is the leading mechanism for verifying the identity of actual device users. Remote authentication is the best solution for remote accessing in smart card environment. In this paper we propose a Password based authentication scheme using ECC for smart card environment, without maintaining the password table by the server. It provides high security at a reasonable computational cost. Furthermore it restricts most of the current attacking mechanisms. It is simple and can be adopted in any kind of lightweight devices.

Password based remote authentication scheme using ECC for smart card

User authentication is a continual problem, particularly with mobile and handheld devices such as Personal Digital Assistants (PDAs), Smartcard, Laptops. User authentication is a difficult for every system providing safe access to precious, private information, or personalized services. User authentication is the primary line of defence for a handheld device that comes into the hands of an unauthorized individual. Password or Personal Identification Number (PIN) based authentication is the leading mechanism for verifying the identity of actual device users. Remote mutual authentication is the best solution for remote accessing in Wi-Fi environment. In this paper we propose a new remote mutual authentication scheme in wireless environment without maintaining the password table. This is based on ElGamal's. It provides high security and mutual authentication at a reasonable computational cost. Furthermore it restricts most of the current attacking mechanisms. It is simple and can be adopted in any kind of lightweight devices. © 2010 Springer-Verlag Berlin Heidelberg.

Most public key crypto systems usefinitefield modulo arithmetic. This modulo arithmetic is applied on real numbers, binary values and polynomial functions. The computation cost is based on how it works with minimum use of scarce resources like processor and memory We have implemented the determination of the multiplicative inverse of a polynomial over GF(2p) with minimum computational cost. The "Extended Euclidean Algorithm" (EEA) has been demonstrated to work very well manually for integers and polynomials. However polynomial manipulation cannot be computerized directly. We have implemented the same by using simple bit wise shift and XOR operations. In small applications like smart cards, mobile devices and other small memory devices, this method works very well. To the best of our knowledge, the proposed algorithm seems to be the first, efficient and cost eective implementation of determining the multiplicative inverse of polynomials over GF(2p) using computers. As this is a pioneering work, the results could not be compared with that of any previous work.

This paper proposes a novel scheme where the key k is generated as discrete logarithm of indices involving prime modulus p and any base value q. This base value q is an element of Zp. The Discrete logarithm values are substituted for k in the encryption equation. During decryption the corresponding k's are used to recover the plaintext. The sender embeds the p, q values along with the encrypted message and transmits it. This obviates the need for sending the full-length key along with the encrypted message. The proposed method ensures higher security in the transmission. The strength of the method lies in the difficulty of guessing p, q values, the entire key need not be transmitted and the full set of ASCII values of the Z256 plane figure in the encryption process. The paper also discusses the difficulty of attempting brute force technique to discover p, q values. As an extension of this work, the authors are exploring the possibility of using the full set of UNICODE values instead of the restricted 8-bit ASCII set. © 2008 Elsevier B.V. All rights reserved.
