This problem can be reduced toestablishing authentic public keys among all the participants -- thesepublic keys then serve to establish a shared secret symmetric key forencryption and authentication of messages.  Unfortunately, in mostreal-world settings, public key infrastructures (PKI) are uncommon anddistributing a secret in a public space is difficult.  Thus, it is achallenge to exchange authentic public keys in a scalable, secure, andeasy to use fashion. We propose GAnGS, a protocol for the secure exchange of authenticatedinformation among a group of people. In contrast to prior work, GAnGSresists Group-in-the-Middle and Sybil attacks by malicious insiders,as well as infiltration attacks by malicious bystanders. GAnGS isdesigned to be robust to user errors, such as miscounting the numberof participants or incorrectly comparing checksums.  We haveimplemented and evaluated GAnGS on Nokia N70 phones.  The GAnGS systemis viable and achieves a good balance between scalability, security,and ease of use.
