SAS-Based Group Authentication and Key Agreement Protocols [chapter]

Sven Laur, Sylvain Pasini
Public Key Cryptography – PKC 2008  
We give a new group message authentication protocol that utilises only limited authenticated communication and show how to combine this protocol with classical key agreement procedures.  ...  New trends in consumer electronics have created a strong demand for fast, reliable and user-friendly key agreement protocols.  ...  It allows building of secure SAS-based group key agreements, as presented in the last section.  ...

2004 Theoretical Computer Science  
In this paper, we propose a new authenticated key agreement protocol, composed of a basic protocol and a dynamic protocol, for dynamic peer groups.  ...  In order to secure communications in dynamic peer groups, authenticated key agreement protocols are required.  ...  Such a protocol is called authenticated group key agreement protocol.

Key handling in wireless sensor networks

Y Li, T Newe
2007 Journal of Physics, Conference Series  
In this paper a selection of key establishment/agreement protocols are reviewed and they are broadly divided into two categories: group key agreement protocols and pair-wise key establishment protocols  ...  Such protocols can employ private-key and/or public key cryptographic algorithms.  ...  Group Key Agreement Protocols A group key agreement protocol relies on shared long-term keys between participants and servers in order to allow participants to construct a group key.  ...

Identity-Based and Inter-Domain Password Authenticated Key Exchange for Lightweight Clients

Ford Long Wong, Hoon Wei Lim
2007 21st International Conference on Advanced Information Networking and Applications Workshops (AINAW'07)  
We propose a four-party password authenticated interdomain key exchange protocol which makes use of properties of identity-based cryptography and secret public keys.  ...  Being password-based and certificate-free, our protocol is lightweight and is suited to lightweight computing environments, such as pervasive computing.  ...  They proposed two four-party password-based authenticated key establishment protocols, which are based on key transport and key agreement techniques, respectively.  ...

Downgrade Resilience in Key-Exchange Protocols

2016 2016 IEEE Symposium on Security and Privacy (SP)  
Key-exchange protocols such as TLS, SSH, IPsec, and ZRTP are highly congurable, with typical deployments supporting multiple protocol versions, cryptographic algorithms and parameters.  ...  In the rst messages of the protocol, the peers negotiate one specic combination: the protocol mode, based on their local congurations.  ...  The TLS 1.3 downgrade countermeasures were formulated in collaboration with Eric Rescorla, Martin Thomson, and the TLS working group. Bhargavan is funded by the ERC grants CRYSP and CIRCUS.  ...

The main practical application of a SAS-MA protocol is Authenticated Key Agreement (AKA) in this communication model, i.e. SAS-AKA, which can be used for so-called "pairing" of wireless devices.  ...  A SAS-MA protocol authenticates arbitrarily long messages sent over insecure channels as long as the sender and the receiver can additionally send a very short, e.g. 20 bit, authenticated message to each  ...  If commitment scheme is (T C , C )-NM and encryption scheme is (T E , E )-SS-CCA, then the Enc-AKA protocol is (T, p)-secure against (n, τ t , τ c )-attacker for p ≥ 2nτ t τ c (2 −k + max( C , E ) and  ...
