Center for Security, Theory and Algorithmic Research

at IIIT Hyderabad deals with designing efficient algorithms for various problems, modeling and abstraction of various concepts, and security guarantees of the computation when operating in an adverse environment. Some of the problems lie at the intersection of multiple domains and require a combination of theoretical rigor and practical acceptability. The center participated actively in societal projects such as Virtual Laboratories for Data Structures and Principles of Information Security.

The center is working on cutting edge problems in several areas such as distributed and multi-core algorithms, quantum information and computation, system and network security, data structures, complexity theory, secure multiparty computation, and the like. Distributed algorithms for symmetry breaking via randomization, and a formal study of fault-tolerance of distributed computing are presently being pursued actively. Secure solutions for problems arising in the field of system security and network security such as security of routing protocols, efficient authentication protocols, are under active study. Some of these use key management techniques. Similarly, data structures for geometric queries such as range searching, maximal and skyline points that support efficient querying are being designed.

The center also runs a post-graduate program, M. Tech., in Computer Science and Information Security under the aegis of the Ministry of Communication and Information Technology (MCIT), Goverment of India. The center teaches several advanced courses in the above areas such as System and Network Security, Research in Information Security, Complexity and Advanced Algorithms, apart from supporting the core courses for the undergraduate programmes of the institute.


CQST Inagurated
