  1. Saumya Shankar IIT Bhubaneswar
    • Title: Advancements in Runtime Enforcement Frameworks: Finite Memory, Compositional Approaches, and Practical Applications
    • Abstract

      In my work, we work on formal runtime enforcement approaches which monitor the execution of a system at runtime and ensure its compliance against a set of formal requirements. An enforcer can be considered as a safety wrapper for the system, (operating next to the execution of untrusted programs), which intervenes when an execution is about to violate the property being enforced. It catches the (untrustworthy) inputs (in the form of a sequence of events) and modifies those into an output sequence that complies with the specified property.

  2. Jyotirmaya Shivottam NISER
    • Title: Graph Mamba
    • Abstract

      In this work, we explore State Space Models (SSMs) to improve long-range performance of Graph Neural Network models on various tasks. We formulate a new approach that incorporates SSMs into the message creation and updation step in Graph Neural Networks, and perform several experiments to verify whether this approach leads to better performance on a set of standard datasets.

  3. Kamakshya Prasad Nayak IIT Bhubaneswar
    • Title: Gaze based analysis of small conversational groups
    • Abstract

      Gaze is critical for applications like human social behaviour analysis, visual navigation, action recognition, human-robot interaction, autism research etc. Gaze target detection or gaze following aims at estimating the person or object at which any subject is looking. Given an input video, the objective is to verify certain hypothesis in movie/series data as well as publicly available video which are natural and not recorded under guidance or supervision. Precisely, we perform the gaze analysis relating to the variation in the number of people in the scene and context under which the discussion is taking place.

  4. Rojalini Tripathy IIT Bhubaneswar
    • Title: Privacy Preserving Peer-to-Peer Federated Learning
    • Abstract

      Federated learning (FL) is an emerging technology that acquires significant attention by the research community due to its manyfold advantages and applications. FL is an area of Machine Learning(ML) that enables multiple data owners to collaboratively train a single model by exchanging model parameters instead of original data. This allows enforcing security and privacy of data as well as provides effective ways of employing AI techniques in different applications. Despite its advantages, FL faces challenges such as dependency on a central server, slow convergence, and impact of message exchanges on system efficiency. In this paper, we are proposing a peer-to-peer federated learning framework using secure multiparty computation. Our proposed framework makes FL not dependent on a central server and provides secure parameter sharing. We have implemented our proposed framework with two different datasets, considering different numbers of clients, and analyzed it. We observe that our framework performs better than existing frameworks.

  5. Kasturi Routray IIT Bhubaneswar
    • Title: Context-Aware Attribute Based Access Control for Cloud-based SCADA Systems
    • Abstract

      Cloud-based SCADA (Supervisory Control and Data Acquisition) systems enable seamless access to internet of things (IoT) operational data for employees at control facilities and operators working on the field for automated control and monitoring of industrial infrastructure. In this work, we introduced a novel approach based on ciphertext policy attribute-based encryption (CP-ABE) to ensure secure and fine-grained access control over data stored in the cloud. Our proposed scheme considers static and dynamic attributes of the users to devise an access policy. Contextual locks are introduced for defining constraints on dynamic attributes. These locks are independent of the user's attribute sets; thus, they don't require decryption keys to be associated with dynamic attributes. This avoids system overhead with frequent changes in contextual parameters. To protect the confidentiality of the access policy, we obfuscate its attributes during the data-sharing process. Moreover, our proposed scheme prevents key escrow attacks on cloud-stored data. Additionally, fog servers are employed to verify the user's contextual attributes and reduce the computational overhead of decryption for end users. Our scheme enhances the security and integrity of remote process control and monitoring in industrial systems while leveraging the benefits of real-time data analysis and decision-making.
