Professor Dan Boneh heads the applied cryptography group and co-direct the computer security lab.

He has been part of an effort to warn about sensitive content without making private communications readable by the process. Coming up with the security measures required a delicate balancing act between cracking down on the exploitation of children while protecting the privacy of users.

Professor Boneh's research focuses on applications of cryptography to computer security. His work includes cryptosystems with novel properties, web security, security for mobile devices, and cryptanalysis.
