Research summary

The Cryptography, Security, and Privacy Research Group at Koc University, founded by Asst. Prof. Alptekin Kupcu in 2010, is tackling world-class problems in the field of applied cryptographic protocols, provable security, privacy preserving and enhancing technologies in general. Our expertise covers secure cloud systems (including storage, databases, and computation), as well as secure payments, fair exchange of items, fair computation, two-party and multi-party secure computation, password-based authentication, secure and private outsourcing, anonymity, and game theory and mechanism design. In relationship to the Royal Society Newton Advanced Fellowship that we are granted, we are working on improving the only known password-based authentication scheme provably secure against dictionary attacks even by the hackers. The original scheme that we previously created, named "Single Password Authentication", is now being improved to provide further protection against phishing and malware, to offer a better usability, to present better formality, and to integrate social aspects and incorporate the social network of the user into the authentication process to improve overall security.
