Anonymity and one-way authentication in key exchange protocols
, 2012
"... Key establishment is a crucial cryptographic primitive for building secure communication channels between two parties in a network. It has been studied extensively in theory and widely deployed in practice. In the research literature a typical protocol in the public-key setting aims for key secrecy ..."

for this setting and develop a model which captures these properties. Our approach allows for clients to choose among different levels of authentication. We also describe an attack on a previous protocol of Øverlier and Syverson, and present a new, efficient key exchange protocol that provides one-way
Robust, Anonymous RFID Authentication with Constant Key-Lookup
"... A considerable number of anonymous RFID authentication schemes have been proposed. However, current proposals either do not provide robust security guarantees, or suffer from scalability issues when the number of tags issued by the system is very large. In this paper, we focus on approaches that rec ..."

anonymity) into one that achieves the same guarantees with constant key-lookup cost even when the number of tags is very large. This approach uses a lightweight one-way trapdoor function and produces protocols that are suitable for deployment into current tag architectures. We then explore the issue
Ace: An Efficient Key-Exchange Protocol for Onion Routing
"... The onion routing (OR) network Tor provides privacy to Internet users by facilitating anonymous web browsing. It achieves anonymity by routing encrypted traffic across a few routers, where the required encryption keys are established using a key exchange protocol. Goldberg, Stebila and Ustaoglu rece ..."

recently characterized the security and privacy properties required by the key exchange protocol used in the OR network. They defined the concept of one-way authenticated key exchange (1W-AKE) and presented a provably secure 1W-AKE protocol called ntor, which is under consideration for deployment in Tor
Post-Quantum Forward Secure Onion Routing (Future Anonymity in Today’s Budget)
"... The onion routing (OR) network Tor provides anonymity to its users by routing their encrypted traf-fic through three proxies (or nodes). The key cryptographic challenge, here, is to establish symmetric session keys using a secure key exchange between the anonymous users and the selected nodes. The T ..."

. The Tor network currently employs a one-way authenticated key exchange (1W-AKE) protocol ntor for this purpose. Nevertheless, ntor as well as other known 1W-AKE protocols rely solely on some classical Diffie-Hellman (DH) type assumptions for their (forward) security, and thus privacy of today’s anony-mous
Secured Public key Authentication and Energy Efficient MAC Implementation in Wireless Sensor Networks
"... Abstract As wireless sensor networks (WSNs) are susceptible to attacks and sensor nodes have limited resources, designing a secure and efficient user authentication protocol for WSNs is a difficult task. Considering that most future large-scale WSNs follow a twotiered architecture, we propose an ef ..."

an efficient and Denial-ofService resistant user authentication scheme for two-tiered WSNs, which imposes very light computational load and requires simple operations such as one-way hash function and exclusive-OR operations. In addition, there is a growing requirement for preserving user anonymity recently
A novel privacy preserving authentication and access control scheme for pervasive computing environments
- IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY
, 2006
"... Privacy and security are two important but seemingly contradictory objectives in a pervasive computing environment (PCE). On one hand, service providers want to authenticate legitimate users and make sure they are accessing their authorized services in a legal way. On the other hand, users want to m ..."

integrates two underlying cryptographic primitives, namely blind signature and hash chain, into a highly flexible and lightweight authentication and key establishment protocol. The scheme provides explicit mutual authentication between a user and a service while allowing the user to anonymously interact

"... Abstract: In the absence of sufficiently optimised public key constructions, anonymous authentication for Radio-Frequency Identification Devices (RFIDs) requires state synchronisation between tags and a trusted server. Active adversaries disrupt this synchrony, making a recovery strategy necessary. ..."
Abstract

based on a lightweight trapdoor one-way function from modular squaring. The solution exploits the fact that synchrony can be recovered even if tags are endowed with only the ability to perform public-key operations, whilst the trusted server is capable of trapdoor computations. The construction
Secure Communication over Diverse Transports
- In ACM Workshop on Privacy in the Electronic Society (WPES
, 2012
"... This paper describes BTP, a protocol that ensures the confidential-ity, integrity, authenticity and forward secrecy of communication over diverse underlying transports, from low-latency, bidirectional transports like TCP to high-latency, unidirectional transports like DVDs sent through the mail. BTP ..."

Once both devices have de-stroyed a given temporary secret, any keys derived from it cannot
