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 …

Order-preserving encryption allows encrypting data, while still enabling efficient range
queries on the encrypted data. This makes its performance and functionality very suitable for …

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 …

Functional encryption (FE) supports constrained decryption keys that allow decrypters to
learn specific functions of encrypted messages. In numerous practical applications of FE …

Functional encryption supports restricted decryption keys that allow users to learn specific
functions of the encrypted messages. Although the vast majority of research on functional …

Cloud computing promises users massive scale outsourced data storage services with much
lower costs than traditional methods. However, privacy concerns compel sensitive data to be …

This paper presents two non-generic and practically efficient private key multi-input
functional encryption (MIFE) schemes for the multi-input version of the inner product …

Recent breakthroughs in cryptography have positioned indistinguishability obfuscation as a
“central hub” for almost all known cryptographic tasks, and as an extremely powerful …

We construct an efficient non-generic private-key functional encryption (FE) for inner-product
values with full-hiding security, where confidentiality is assured not only for encrypted data …

In light of security challenges that have emerged in a world with complex networks and
cloud computing, the notion of functional encryption has recently emerged. In this work, we …
