Talk title: Access-Controlled IoT and Human Interactivity: Reputation, Transactions and Blockchain
Talk abstract:As indicated in the IEEE Cyber Security document “Building Code for the Internet of Things”: “Even in the case where isolation boundaries are well-defined, complete, and sufficient to protect a system or component against compromise, interacting IoT systems might require well-defined ways of adjusting this isolation to access parts of another system (for example, in the case of a smart cities subsystem compensating for another during a natural disaster). The decision process governing this adjustment of the isolation boundary needs to be able to gauge the context of the situation and the trustworthiness of the entities being considered for inclusion inside the boundary.” As elements of a methodology to securely and efficiently instantiate this decision process while resisting adversarial traffic analysis and undetected interference, this talk will address how to set up dedicated maintainable “communication lines” and utilize permissioned blockchains in order to establish and update the reputation of devices relative to their certified attributes and the tasks they are suitably equipped to engage in. The system inherits the desired transaction unlinkability property from the US Department of Transportation- piloted Security Credential Management System PoC for V2V/V2X communications, and cryptographically binds on-chain and off-chain operations with respect to authentication, authorization and preservation of confidentiality.
Biography: Dr. David W. Kravitz is VP of Crypto Systems Research at DarkMatter, and heads DarkMatter’s
blockchain team that is focused on providing an IoT-compatible access-controlled transaction platform. His extensive information security
experience spans a wide range of application areas, including voice- and data- critical infrastructure, digital rights management, payments,
smart grid, IoT, and high-value assets transfer. He began his career at the National Security Agency, where as Senior Technical Advisor he “combined his exceptional skills in protocol and algorithm design with his evaluation capabilities to profoundly enhance the security posture of communications,” as stated in the Certificate of Achievement he was awarded by the Director of NSA. He has also held senior positions at Sandia National Laboratories, CertCo/Bankers Trust Electronic Commerce, Digital Video Express, Wave Systems Corp., Motorola Labs, Certicom Research/BlackBerry, and IBM Research. He was the principal architect of the Membership Services identity management framework of the Linux Foundation’s Hyperledger Fabric project for permissioned blockchain, and invented the Digital Signature Algorithm of the FIPS 186 Digital Signature Standard, the elliptic curve variant of which, ECDSA, underlies Bitcoin and Ethereum. He serves as a Technical Advisor for CENTRI, and holds a Ph.D. and Masters in Electrical Engineering – Systems from University of Southern California, a Masters in Mathematical Sciences from Johns Hopkins University, and a Bachelors in Mathematics from Rutgers University.
