ePrint Report: Constant Input Attribute Based (and Predicate) Encryption from Evasive and Tensor LWE

Shweta Agrawal, Melissa Rossi, Anshu Yadav, Shota Yamada

Constructing advanced cryptographic primitives such as obfuscation or broadcast encryption from standard hardness assumptions in the post quantum regime is an important area of research, which has met with limited success despite significant effort. It is therefore extremely important to find new, simple to state assumptions in this regime which can be used to fill this gap. An …
