CS 579:Foundations of Cryptography
This course provides a broad introduction to cornerstones of security
(authenticity, confidentiality, message integrity, and non-repudiation)
and the mechanisms to achieve them as well as the underlying
mathematical basics. Topics include: block and stream ciphers,
public-key systems, key management, certificates, public-key
infrastructure (PKI), digital signature, non-repudiation, and message
authentication. Various security standards and protocols such as DES,
AES, PGP, and Kerberos, are studied. |

CS 600:Advanced Algorithm Design and Implementation
Design, implementation, and asymptotic time and space analysis of advanced algorithms, as well as analyzing worst-case and average-case complexity of algorithms. Students will be expected to run experiments to test the actual performance of the algorithms on sample inputs. Introduction to NP-complete problems and approximation algorithms.

CS 693:Cryptographic Protocols
This course covers the design and analysis of security protocols, and studies different attacks and defenses against them. Topics include: signature and authentication protocols, privacy, digital rights management, security protocols for wired, wireless and distributed networks, electronic voting, payment and micropayment protocols, anonymity, broadcast encryption and traitor tracing, quantum cryptography, and visual cryptography. The course includes a project. |

| | | Research | | My research interests are in cryptography and algorithmic number theory. In the field of cryptography, my research is focused on wireless security, secret sharing, privacy, and biometrics, and my contributions range from analysis to protocol design. In algorithmic number theory, my research is centered on lattice theory, in particular on developing new algorithms and heuristics for lattice basis reduction. |
