Since the term first coined in 1999, the Internet of Things (IoT) has gained significant
momentum in connecting physical objects to the Internet and facilitating machine-to-human …

Blockchain technology plays a significant role in the industrial development. Many industries
can potentially benefit from the innovations blockchain decentralization technology and …

We describe a comparatively simple fully homomorphic encryption (FHE) scheme based on
the learning with errors (LWE) problem. In previous LWE-based FHE schemes, multiplication …

In this work, we study indistinguishability obfuscation and functional encryption for general
circuits: Indistinguishability obfuscation requires that given any two equivalent circuits C_0 …

We introduce a new technique, that we call punctured programs, to apply indistinguishability
obfuscation towards cryptographic problems. We use this technique to carry out a systematic …

We construct the first (key-policy) attribute-based encryption (ABE) system with short secret
keys: the size of keys in our system depends only on the depth of the policy circuit, not its …

We describe plausible lattice-based constructions with properties that approximate the
sought-after multilinear maps in hard-discrete-logarithm groups, and show an example …

Blockchain technologies recently received a considerable amount of attention. While the
initial focus was mainly on the use of blockchains in the context of cryptocurrencies such as …

Functional encryption is a modern public-key paradigm where a master secret key can be
used to derive sub-keys SK_F associated with certain functions F in such a way that the …

In an attribute-based encryption (ABE) scheme, a ciphertext is associated with an ℓ-bit public
index ind and a message m, and a secret key is associated with a Boolean predicate P. The …
