Cloud computing is a long‐standing dream of computing as a utility, where users can store
their data remotely in the cloud to enjoy on‐demand services and high‐quality applications …

Cryptography is an indispensable tool used to protect information in computing systems. It is
used everywhere and by billions of people worldwide on a daily basis. It is used to protect …

Deciding “greater-than” relations among data items just given their encryptions is at the
heart of search algorithms on encrypted data, most notably, non-interactive binary search on …

Indistinguishability obfuscation (IO) is a tremendous notion, powerful enough to give rise to
almost any known cryptographic object. Prior candidate IO constructions were based on …

The arrival of indistinguishability obfuscation (i O i O) has transformed the cryptographic
landscape by enabling several security goals that were previously beyond our reach …

Functional encryption (FE) is an extremely powerful cryptographic mechanism that lets an
authorized entity compute on encrypted data, and learn the results in the clear. However, all …

In a functional encryption scheme, secret keys are associated with functions and ciphertexts
are associated with messages. Given a secret key for a function f, and a ciphertext for a …

We propose the first construction for achieving adaptively secure functional encryption (FE)
for poly-sized circuits (without complexity leveraging) from indistinguishability obfuscation (i …

We extend the reach of functional encryption schemes that are provably secure under
simple assumptions against unbounded collusion to include function-hiding inner product …

In a functional encryption (FE) scheme, the owner of the secret key can generate restricted
decryption keys that allow users to learn specific functions of the encrypted messages and …
