    Extended game theoretic dirichlet based collaborative intrusion detection systems
    (Springer Verlag service@springer.de, 2016) Paul, S.; Makkar, T.; Chandrasekaran, K.
    Security has always been one of the key issues of any man-made system, this paved the way for a submodule or application or a device to monitor or system for malicious activities. This system or submodule or device is known as Intrusion Detection System (IDS). As technology evolves so does the associated threats and thus the intrusion detection system needs to evolve. Game theory throws in a different perspective which have not been looked upon much. Game theory provides a way of mathematically formalizing the decision making process of policy establishment and execution. Notion of game theory can be used in intrusion detection system in assisting in defining and reconfiguring security policies given the severity of attacks dynamically. We are trying to formulate a robust model for the theoretical limits of a game theoretic approach to IDS. The most important flaw of game theory is that it assumes the adversary’s rationality and doesn’t take into consideration multiple simultaneous attacks. Therefore, a collaborative trust and Dirichlet distribution based robust game theoretic approach is proposed which will try to resolve this issue. Reinforced learning approaches using Markov Decision Process will be utilized to make it robust to multiple simultaneous attacks. © Springer Science+Business Media Singapore 2016.

    Communication Architecture for Autonomous Aerial Traffic Management
    (Institute of Electrical and Electronics Engineers Inc., 2022) Paul, S.; Jana, S.; Chopra, O.; Ratnoo, A.; Ghose, D.
    This paper presents a multi-agent communication paradigm for autonomous aerial traffic management. Multi-drone missions based on the existing ROS-based communication architecture heavily depend on the master node, and communication delay between nodes might not be sufficient for efficient inter-agent collision avoidance. In this paper, we have proposed a hybrid ROS-ROS2 communication architecture for centralised traffic management with the provision of distributed communication for collision avoidance and conflict resolution at intersections. The base station server responsible for traffic management runs on a ROS2 environment, ROS is used for communication with each onboard autopilot, and an intermediate add-on-module interfaces ROS and ROS2 messages. The content of the communication packets between the different nodes is decided based on the design requirements. Overall communication architecture is validated through simulation and hardware experiments. © 2022 IEEE.

    A Novel Approach of Network Security Using Genetic Algorithm
    (Springer Science and Business Media Deutschland GmbH, 2024) Bera, A.; Sinha, D.; Maity, S.; Paul, S.
    This article focuses on providing security of sensitive information and message transmission using symmetric key cryptosystem based on genetic algorithm and combined with mathematical and bitwise operators to provide confidentiality, authenticity, integrity, and nonrepudiation of the messages. A plain text is encrypted using a private key and resizer parameter taken as input from the user to produce an intermediate cipher which is further encrypted using genetic algorithm and mathematical operations to obtain the final cipher. The level of complexity of encryption and the size of the final cipher text can be regulated using the resizer parameter. The final cipher is decrypted first to obtain an intermediate cipher, which in turn is decrypted using the private key to get back the plain text. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
