    • Talk 2 (10:45 - 11:10)
      • Title: Light PKI: Need of the Hour
      • Speaker: Prof. Ashutosh Saxena, Dean R & D, CMR Technical Campus
      • Abstract: The most well-known encryption technique is symmetric cryptography, which is very efficient but presents us with several challenges like transmitting the keys, storing the keys securely and renewing the keys. Asymmetric cryptography solves these challenges in an easier way where a private key is kept secret, and a public key is available to everybody. Messages encrypted with one of the keys in such a pair can be decrypted with the other key in the pair, since the keys are mathematically linked. However, it also suffers on speed as the asymmetric algorithms are approximately 1,000 times slower than symmetric algorithms. Therefore, entities use asymmetric cryptography to authenticate themselves, generate symmetric keys, and exchange the symmetric keys encrypted with the asymmetric algorithm. When the entities have received their symmetric keys, they use symmetric cryptography to protect their communication. Thus, both symmetric and asymmetric cryptography is needed for efficient communication security, especially in the scenario of IoT.However, many small, battery-powered IoT devices lack the required computing resources to use traditional PKI protocols. Most current deployments with constrained devices are not secured at all or only by shared keys, PINs or passwords. As a result, there is a large risk of hacker attacks and eavesdropping. This work presents a broad framework for PKI certificate management which can be easily used in the IoT having secureenrolment and overhead reduction.

    • Talk 6 (12:30 - 12:50)
      • Title: Design of Security Protocols for Dynamic Charging of Electric Vehicles
      • Speaker: Dr. Goutam Reddy, NIT Andhra Pradesh
      • Abstract: Global use of electric vehicles has risen, necessitating the development of an efficient charging method. While static and partially dynamic charging are currently used, they diminish a vehicle's ability to stand charge, which contributes to range anxiety. In the near future, dynamic charging of electric vehicles will be a promising technology, allowing an electric vehicle to charge autonomously while in motion. However, assessing the security risks before enabling dynamic charging is mandatory, with authentication being a necessary step. As a result, developing secure authenticated key-agreement procedures for the interacting entities is as critical as the dynamic charging application itself in this context.

    • Talk 7 (12:50 - 13:15)
      • Title: An efficient hyperchaotic keystream generator using perturbance process for Public Key Infrastructure Applications
      • Speaker: Dr. K K Soundra Pandian, Scientist 'D', Office of CCA
      • Abstract: A need for secured communication under hostile condition mandated to incorporate the cryptographic methods in a system. Chaos is another promising paradigm which offshoots from nonlinear dynamics where its randomness has no stochastic origin. Hence a deterministic Pseudo Random Number Generator (PRNG) plays a vital role in chaotic-cryptography. Though many PRNG based chaotic systems are proposed, the low- key space chaotic systems and the finite precision of processor deteriorates the periodic function. The intent of this paper is to achieve larger Lyapunov exponent by our proposed system. The proposed system provides an improved key spacing and randomness with a novel approach of perturbing the sequence obtained from the hyperchaotic system with Non-Linear Feedback based Self-Shrinking Generators (NLFSR-SSG). As a result, improved Lyapunov exponents (2.94, 0.1, 0, -15.341) are obtained and also a dynamic key stream using the proposed hyperchaotic system is generated with high resistance towards cryptanalytic attacks.

    • Talk 9 (14:25 - 14:50)
      • Title: Hide-and-Seek: Machine Learning In Encrypted Domain
      • Speaker: Prof. Yogachandran Rahulamathavan. Loughborough University London, UK
      • Abstract: Machine Learning models were built using a huge amount of high-quality and application-specific data. Even though the machine learning models can only be trained at places where the data is available, anyone can use the trained model for classification tasks via the Internet. While it sounds revolutionary, the trained ML models are not readily available to users in healthcare, finance, or marketing due to privacy issues. Users do not want to share their sensitive data with service providers due to a lack of trust. Simply encrypting the data only protects them during storage and transmission. Researchers and industries are developing novel techniques known as privacy-preserving techniques to process the data in an encrypted domain to tackle the privacy issue. Homomorphic encryption plays a key role in developing privacy-preserving machine learning algorithms. While homomorphic properties exist in traditional cryptographic schemes such as RSA, this talk will focus on fully homomorphic encryption from lattice-based cryptography. We will also go through the state-of-the-art works, challenges and future trend in this domain.
      • Bio: Yogachandran received his PhD degree in Signal and Information Processing from Loughborough University in 2011 and then worked as a postdoctoral research associate for six months on encrypted signal processing technique for privacy-preserving multimedia Big data processing. Subsequently he joined City University London as a research fellow in information security within the School of Mathematics, Computer Science and Engineering in 2012.
        Yogachandran's research interests are on developing novel algorithms for Internet-of-Things, especially on advancing privacy-preserving data processing methods for cyber-physical systems such as cloud and smart networks, application of which spans mhealth, smart home, smart grid and connected cars. This involves processing big multimedia data in cloud system without violating user's privacy. For this he redesigned the state-of-the-art machine learning techniques such as support vector machine, Gaussian mixture models, and Linear Discriminant analysis using cryptographic primitives to work on encrypted domain.

    • Talk 11 (15:05 - 15:20)
      • Title: A Signature based Authentication Modality for Adaptive Authentication in Healthcare Devices
      • Speaker: Vivin Krishnan, Software Engineer, IBM
      • Abstract: Evolving threat vectors arising from rapid penetration of internet-oriented applications has posed an increased risk to confidential data. While traditional authentication strategies have upgraded into multi-factor schemes, there continues to be a gap in terms of usability. Systems and enterprises are now gravitating towards an Adaptive authentication-based approach that uses the user's past behavior to offer protection in this scenario. This paper proposes a signature-based authentication modality that integrates with an adaptive authentication system. The system validates the contextual attributes of the user in every request. The use of an open standard allows integration with existing systems and serves as a means of verifying the client's authenticity. Formal analysis of the protocol has been done using Scyther and all the claims have been verified.
