Our attack breaks the multipartite key-agreement protocol in polynomial time by generating an equivalent user private key; it also... Weban attack of GGH multilinear maps [GGH13] without any low-level encodings of zero. GGH maps were proposed by Garg et al. and broken by a so-called zeroiz-ing attack by Hu and Jia [HJ15]. Since their attack extensively utilizes low-level encodings of zero, it does not work without them, and no polynomial-time attack
