Design of a Hybrid Security Protocol based on Cryptographic Algorithms

Abstract: With increase in the use of the internet, the need to secure data is also increased. The present symmetric and asymmetric algorithms provide secure systems, but with many limitations. In the emerging world need for rapid accessing the data is increasing, a blend of both efficiency and security is required to cater the day-to-day needs. To ensure efficiency and security of the message hybrid security protocols are developed. Hybrid security protocol combines the advantages of traditional algorithms, such that more secure and efficient systems can be developed. A new hybrid protocol is developed using AES, ECC and ECDH, which in terms increase efficiency of existing protocols and provide a better security by adding an extra layer of security to the traditional AES algorithm.

Performance Test of WAP Gateway Over Web Server Using OPNET

The Security for the portable devices such as mobile phones,iPad and laptops becoming extremely important day by day.The intermediates such as gateway are the main source for communication through wireless media. In today's era, maintaining the transport level security amongst cellular devices like mobile phones and PDA(Personal Digital Assistant) become the most burning issue.During communications of smart phones with the web server through broadband method pass communication through the gateway known as Wireless Applications Protocol. The main purpose of WAP gateway is to transfer all the protocol used in WAP to the protocols used on the internet server. The WAP proxy server uses marshalling and unmarshalling methodology for the content to reduce the size of the data that has been sent through the wireless link. Further, the communication between the mobile phones and wireless application protocol is secured by using the security protocol called WTLS. The communication between the WAP gateway and web server is secured through the TLS/SSL security protocols. This paper simulates an assessment of wireless and wired networks using OPNET simulation tools. This paper simulated 2 different scenarios comparing wireless mobile client communication using WTLS gateway MD5_RSA encryption and Firewall gateway TLS encryption using MD5_RSA.The investigation results shows how the end to end security takes place between wireless clients to web servers using hybrid security protocol.

An Optimized Energy Saving Model for Hybrid Security Protocol in WMN

Wireless mesh network (WMN) is an emerging field of research with a large number of applications and associated constraints. WMN is used as a new wireless broadband network structure which is completely based on IP technologies. It has the ability to produce high speed and wide area of coverage, and it also provides a high capacity for handling the nodes. To help authenticate messages, identify valid nodes and remove malevolent node. Security and privacy are two major problems in WMN. Unfortunately, in mesh networks most privacy-preserving schemes are vulnerable to attacks. The most dangerous attack to be noted in mesh network is node impersonation attack which makes them more insecure. WMN is said to be an emerging wireless broadband network structure, where it is completely based on the IP technologies. The mesh routers and clients play a vital role in the mesh networks where they act as a backbone and help the mesh networks to achieve their target in an efficient way. The important factor in the wireless mesh network is to provide a trusted handoff between the nodes, and they need an access authentication effectively. This area can be considered as the vulnerable one, and there is a chance for some attacks which makes the network unstable. Achieving the seamless handoff is a complex case in every dynamic heterogeneous wireless mesh network. This is because providing a security for such kind of structure is very difficult and the existing procedure for providing security for heterogeneous network gives protection for certain types of attacks. In this paper, we use an optimization algorithm for finding the best position for deploying mesh routers and for developing a hybrid and secured model for detecting node impersonation attack by combining ECDSA with CHAP. We also show how our proposed model can handle the throughput, authentication delay, etc., without facing any problem such as energy consumption and delay.

Robust Hybrid-Security Protocol for HealthCare Systems

Security and Privacy are increasing concerns in nearly all industries. Recently, the use of Electronic Health Records (EHR) has been expanded to reduce the cost and provide efficient healthcare services. Therefore, it is compulsory to ensure that EHR provides the desired levels of security and privacy. In this paper, we introduce a robust hybrid-security protocol in order to increase the level of privacy and reduce the communication cost between parties. It is a secure multifactor remote user protocol that allows the patient to securely exchange her medical information with her doctor over an insecure communication channel. It makes use of three-factor authentication technique in order to protect users’ identities (i.e. password, smart device, biometrics.) Biometrics are difficult to forge, steal, or forget. A simulation of the proposed protocol is carried out by the automated formal tool, AVISPA.

IEEE 802.11p and Visible Light Hybrid Communication Based Secure Autonomous Platoon

Autonomous vehicle platoon is an enhancement of autonomous behavior, where vehicles are organized into groups of close proximity through wireless communication. Platoon members mostly communicate with each other via the current dominant vehicular radio frequency (RF) technology, IEEE 802.11p. However, this technology leads security vulnerabilities under various attacks from adversaries. Visible light communication (VLC) has the potential to alleviate these vulnerabilities by exploiting the directivity and impermeability of light. Utilizing only VLC in vehicle platoon, on the other hand, may degrade platoon stability since VLC is sensitive to environmental effects. In this paper, we propose an IEEE 802.11p and VLC-based hybrid security protocol for platoon communication, namely SP-VLC, with the goal of ensuring platoon stability and securing platoon maneuvers under data packet injection, channel overhearing, jamming, and platoon maneuver attacks. We define platoon maneuver attack based on the identification of various scenarios where a fake maneuver packet is transmitted by a malicious actor. SP-VLC includes mechanisms for the secret key establishment, message authentication, data transmission over both IEEE 802.11p and VLC, jamming detection and reaction to switch to VLC only communication and secure platoon maneuvering based on the joint usage of IEEE 802.11p and VLC. We develop a simulation platform combining realistic vehicle mobility model, realistic VLC and IEEE 802.11p channel models, and vehicle platoon management. We show the functionality of the SP-VLC protocol under all possible security attacks by performing extensive simulations. Our findings demonstrate that SP-VLC protocol generates less than $0.1\%$ difference in the speed of and distance between platoon members during security attacks in comparison to $25\%$ and $10\%$ in that of previously proposed IEEE 802.11p and IEEE 802.11p-VLC hybrid protocols, respectively.

Hybrid Cryptography Algorithms for Enhanced Adaptive Acknowledgment Secure in MANET

The mobile adhoc network is a group of mobile nodes without having the fixed infrastructure. Due to the infrastructure less network and distributed nature, make mobile adhoc network susceptible to malicious attackers. So, we use an intrusion detection system called Enhanced Adaptive ACKnowledgement (EAACK) especially for mobile adhoc networks. Based on the digital signature algorithm (DSA) and RSA the EAACK is designed. To enhance the strength of the security in the mobile adhoc networks, we introduce an innovative approach called Hybrid Security Protocol that provides integrity, confidentiality and authentication. This Hybrid Security Protocol consists of Cryptography based on Elliptic curve, Dual-RSA algorithm and Message Digest MD5. Encryption is achieved by using Elliptic Curve Cryptography, Dual-RSA algorithm for authentication and MD-5 for integrity. By using a combination of both symmetric and asymmetric cryptographic techniques, we achieve better security with integrity. Key Terms:Digital Signature, Enhanced Adaptive Acknowledgment (EAACK), Mobile Ad hoc Network (MANET), Elliptic Curve Cryptography, Dual-RSA, Message Digest-5.

Hybrid security protocol for wireless body area networks

AbstractWireless body area networks (WBANs) are receiving a significant interest as an emerging technology in next generation wireless networks. Security challenges as well as this interest are also beginning to rise to the surface. We derived specific security requirements from WBANs, and proposed a new hybrid security protocol for WBANs which satisfies these requirements. This proposed protocol dealt with the overall security including up to the in‐ on‐, and out‐body, and utilized two heterogeneous cryptosystems (the symmetric and asymmetric) for diverse environments of WBANs. Our protocol shows that it satisfies more security requirements than existing security protocols including the overall coverage of WBANs. Copyright © 2010 John Wiley & Sons, Ltd.

A hybrid security protocol for sensor networks

Sensor nodes used to transmit sensitive data, especially in military applications, require securing the data transmitted through the WSNs to maintain the confidentiality of the data and authenticate the participating sensor nodes. Since sensor nodes suffer from limited resources, in memory storage, computing power, energy capabilities and transmission rates, available network security protocols are inadequate. Symmetric algorithms cannot provide the same degree of security as public key algorithms, leading us to devise a new algorithm SHESP that uses public keys within the limitations of sensor nodes. This paper presents a way to utilise existing public key algorithms such as RSA, Diffie-Hellmann and elliptic curve in the field of WSN security by dividing the network into clusters. Our algorithm supplies data confidentiality, node authentication and data integrity while remaining within acceptable memory, time and energy constraints. We provide theoretical and experimental evidence to validate our algorithms. Results reveal significant improvement in data availability, data confidentiality and authenticity while reducing the communication and computation overhead.
