Security and privacy are critical for the success of many emerging technology trends. Among these trends, big data technologies and smart infrastructures are especially important due to their significant impact on the society in general and science at large. In this talk, I will first highlight some of the security and privacy challenges of these technology trends. I will then describe my contributions towards trustworthy big data technologies and smart-infrastructures.
A fundamental challenge in big data technologies is how to achieve the search/analysis and privacy of sensitive data simultaneously. Addressing this challenge will be a key enabler for important domains such as privacy-preserving healthcare informatics, computing clouds and finance systems. To this end, we initiated the research program Privacy Enhancing Technologies for Big Data Analytics at Bosch Research. This research includes development of new Searchable Encryption schemes that permit practical searches on the encrypted data. The second part of my talk will concentrate on the security of smart-infrastructures. The challenge here is to provide scalable and reliable security in distributed and heterogeneous scenarios (e.g. smart-grid and intra/inter car network). To this end, I have developed a series of authentication and integrity mechanisms, which can address these security requirements in an efficient and scalable manner. Finally, I will discuss my future research agenda that focuses on important security and privacy needs of big data technologies and smart-infrastructures.


Dr. Attila Altay Yavuz has been a member of the security and privacy research group at the Robert Bosch Research and Technology Center North America since December 2011. He is also an adjunct faculty at the University of Pittsburgh's School of Information Sciences. He received his PhD degree in Computer Science from North Carolina State University in August 2011. He received a BS degree in Computer Engineering from Yildiz Technical University (2004) and a MS degree in Computer Science from Bogazici University (2006), both in Istanbul, Turkey.
His expertise is in the areas of applied cryptography, network security and privacy. He leads a corporate-funded research program, "Privacy Enhancing Technologies for Big Data Analytics", which aims at developing practical searchable encryption schemes. In addition, he also conducts research on the topic of "Efficient Security Mechanisms for Smart Infrastructures". His work has frequently appeared in respected conferences and journals. He also has many patents to his name, that have shaped real-world products today in the market.
