Provably-Secure Authenticated Group Diffie-Hellman KeyExchange

PDF Version Also Available for Download.

Description

Authenticated key exchange protocols allow two participantsA and B, communicating over a public network and each holding anauthentication means, to exchange a shared secret value. Methods designedto deal with this cryptographic problem ensure A (resp. B) that no otherparticipants aside from B (resp. A) can learn any information about theagreed value, and often also ensure A and B that their respective partnerhas actually computed this value. A natural extension to thiscryptographic method is to consider a pool of participants exchanging ashared secret value and to provide a formal treatment for it. Startingfrom the famous 2-party Diffie-Hellman (DH) key exchange protocol, ... continued below

Description

Authenticated key exchange protocols allow two participantsA and B, communicating over a public network and each holding anauthentication means, to exchange a shared secret value. Methods designedto deal with this cryptographic problem ensure A (resp. B) that no otherparticipants aside from B (resp. A) can learn any information about theagreed value, and often also ensure A and B that their respective partnerhas actually computed this value. A natural extension to thiscryptographic method is to consider a pool of participants exchanging ashared secret value and to provide a formal treatment for it. Startingfrom the famous 2-party Diffie-Hellman (DH) key exchange protocol, andfrom its authenticated variants, security experts have extended it to themulti-party setting for over a decade and completed a formal analysis inthe framework of modern cryptography in the past few years. The presentpaper synthesizes this body of work on the provably-secure authenticatedgroup DH key exchange.
