Multilinear maps
blog
I’m looking at Indistinghuishability Obfuscation (iO). Which seems to be coming from Fully Homomorphic Encryption (FHE), Functional Encryption (FE) and Multilinear Maps (MM).
Watching Sanjam Garg introduction to this iO, I noticed one interesting slide that puts things into context:
- 2 parties key exchange in 1976 (DH)
- 3 parties in 2000 (Joux)
- X parties in 2013 (GGH)

EDIT:
Apparently, @Leptan is telling me that all multiparty key exchange using multilinear maps are broken as of today. Cf Cryptanalysis of GGH Map
