AntipaDavid Kravitz joined Certicom Research in 2010 as a Principal Member of the Technical Staff. David leads standardization and research efforts developing new cryptographic primitives and employing these primitives to meet information security requirements in emerging application spaces like personal area and mobile networks.

David has over twenty-five years of cryptography and information security experience. Prior to joining RIM, David was a Fellow of the Technical Staff at Motorola, the Chief Cryptographer for Orion Security Solutions, Chief Scientist for Wave Systems Corp., Chief Scientist - Security Systems for Digital Video Express, Vice President at CertCo/Bankers Trust, and held senior technical positions at Sandia National Laboratories and the National Security Agency. He has published and patented on: methods to balance digital rights restrictions against ease of use across multiple platforms through compromise containment (as adopted by Open Mobile Alliance); hierarchical key management, and a new encryption/decryption mode to securely handle two-block messages; an architecture that enables consumers to access services and content from multiple providers without jeopardizing the privacy interests of consumers or the intellectual property rights of providers, through introduction of a trust server that mediates the conferral and revocation of trust relationships; highly scalable on-line payments achieved via task decoupling; and trustee-based tracing extensions to anonymous cash. He had discovered a subtle cryptographic flaw in an electronic money system that Sandia was responsible for evaluating, and was awarded a Certificate of Achievement by the Director of NSA for his cumulative work in protocol and algorithm design and evaluation. In addition to his work in digital rights, key management and digital payment systems, David is the inventor of the Digital Signature Algorithm (DSA) standardized in FIPS Publication 186, Digital Signature Standard. David holds a Ph.D. in Electrical Engineering from the University of Southern California specializing in Cryptography and Coding Theory.
