He works in various fields of computer science, mainly the foundations of cryptography. He is notable for initiating research on public key systems secure against chosen ciphertext attack and creating non-malleable cryptography, visual cryptography (with Adi Shamir), and suggesting various methods for verifying that users of a computer system are human (leading to the notion of CAPTCHA).^[1] His research on Small-bias sample space, give a general framework for combining small k-wise independent spaces with small ${\displaystyle \epsilon }$-biased spaces to obtain ${\displaystyle \delta }$-almost k-wise independent spaces of small size.^[2] In 1994 he was the first, with Amos Fiat, to formally study the problem of practical broadcast encryption.^[3] Along with Benny Chor, Amos Fiat, and Benny Pinkas, he made a contribution to the development of Traitor tracing, a copyright infringement detection system which works by tracing the source of leaked files rather than by direct copy protection.^[4]
