Abstract
Disclosed is an adaptively secure multiparty non-interactive key exchange (NIKE) from polynomially hard indistinguishability obfuscation and other standard assumptions. This improves on all prior such protocols, which required sub-exponential hardness. Several compilers are established which simplify the task of constructing new multiparty NIKE protocols, and also establish a close connection with a particular type of constrained PRF.
