Multi-party Diffie-Hellman Key Exchange + Peer-to-peer + JAVA

 

00:07 demo prebuilt version of app. with 5 communicating and one eavesdropper peers

01:16 PassiveEve picking up messages from Alice, Bob, Carla , Dave, and Elena

01:32 Alice picking up messages from Elena

01:42 Bob picking up messages from Alice

01:52 Carla picking up messages from Bob

02:02 Dave picking up messages from Carla

02:14 Elena picking up messages from Dave

03:30 Alice, Bob, Carla, Dave, and Elena obtain shared key

05:20 PassiveEve can see p, alpha, alpha^a, alpha^b, alpha^c, alpha^d, alpha^e etc...

but cannot use any combination of those to efficiently reproduce alpha^abcde

00:07 demo prebuilt version of application

01:05 PassiveEve picking up messages from Alice, Bob, and Carla

01:22 Alice picking up messages from Carla

01:32 Bob picking up messages from Alice
