Variation of GGH15 Multilinear Maps
Recently, Coron presented an attack of GGH15 multilinear maps, which breaks the multipartite Diffie-Hellman key exchange protocol based on GGH15. In this paper, we describe a variation of GGH15, which seems to thwart known attacks. Keywords. Multilinear maps, zeroizing attack, MPKE, witness encryption, LWE
