To students interested in working with me

If you are not yet a student at Maryland, please do not e-mail me asking to be admitted to our graduate program. Admissions are decided by a committee, and individual faculty members cannot admit students on their own. Everything you need to know about admissions can be found on the information page for prospective graduate students.
If you are a student at Maryland:
I am always seeking motivated PhD students in computer science who are interested in studying cryptography and theoretical aspects of computer security. (To see what types of problems I work on, look at my research interests or read some of my papers.) If you are interested in working with me, I strongly recommend that you take a graduate course in cryptography, or CMSC 456 (undergraduate cryptography) with me. You can also read my textbook in lieu of taking the undergraduate course.
If you send me a generic email, you can be assured that I will ignore it.
I occasionally have suitable projects for Master's students or PhD students in other departments as well. However, please note that I do not fund students until they have worked successfully with me at least one semester.
I also occasionally have implementation projects available for talented undergraduates who have taken CMSC 414 or CMSC 456, or who are mathematically inclined.
Important: If you send me e-mail about the above, please put the phrase "graduate research" in the subject line. Otherwise, your email is likely to be mislabeled as spam and discarded.
