TLDR
New protocols based on both passkeys and numeric comparison (short authenticated strings) are presented and security properties and group management for these protocols are discussed.Abstract:
A security association specifies the cryptographic keys and algorithms to be used for secure communication among the participants in the association. Key agreement in ad hoc scenarios, that is, without key management infrastructure is a challenging task, in particular, if the security association should involve a group of entities. In this paper, existing pairwise ad hoc key agreement protocols are extended for groups of arbitrary number of entities. New protocols based on both passkeys and numeric comparison (short authenticated strings) are presented. Also security properties and group management for these protocols are discussed.read more

SPATE: small-group PKI-less authenticated trust establishment
Yue-Hsun Lin,Ahren Studer,Hsu-Chin Hsiao,Jonathan M. McCune,King-Hang Wang,Maxwell Krohn,Phen-Lan Lin,Adrian Perrig,Hung-Min Sun,Bo-Yin Yang +9 more
TL;DR: The implementation of SPATE on Nokia N70 smartphones allows users to establish trust in small groups of up to eight users in less than one minute, and the example SPATE applications provide increased security with little overhead noticeable to users once keys are established.

Chia-Hsin Owen Chen,Chung-Wei Chen,Cynthia Kuo,Yan-Hao Lai,Jonathan M. McCune,Ahren Studer,Adrian Perrig,Bo-Yin Yang,Tzong-Chen Wu +8 more
TL;DR: GAnGS, a protocol for the secure exchange of authenticated information among a group of people, is proposed and designed to be robust to user errors, such as miscounting the number of participants or incorrectly comparing checksums.

A Survey of User Interaction for Spontaneous Device Association
TL;DR: A novel taxonomy is used to structure the survey with respect to the different conceptual models and types of user action employed for device association, and an in-depth survey of existing techniques discussing their individual characteristics, benefits, and issues is provided.

Authentication protocols based on low-bandwidth unspoofable channels: A comparative survey
Long Hoang Nguyen,A. W. Roscoe +1 more
TL;DR: In this article, an analytical survey of authentication protocols of this type is given, and a number of strategies used to build interactive pair-wise and group protocols that minimise the human work relative to the amount of security obtained as well as optimising the computation processing are discussed.

Encrypted key exchange: password-based protocols secure against dictionary attacks
TL;DR: A combination of asymmetric (public-key) and symmetric (secret- key) cryptography that allow two parties sharing a common password to exchange confidential and authenticated information over an insecure network is introduced.

Diffie-Hellman key distribution extended to group communication
TL;DR: This paper considers a class of protocols that are natural extensions of DiffieHellman to the n-party case and argues that these protocols are optimal with respect to certain aspects of protocol complexity.

Talking to Strangers: Authentication in Ad-Hoc Wireless Networks.
TL;DR: This paper presents a user-friendly solution, which provides secure authentication using almost any established public-key-based key exchange protocol, as well as inexpensive hash-based alternatives, over the wireless link.
