abstract = {Non-repudiation protocols are of great importance for electronic interactions. Different protocols have been proposed in this field, progressively relaxing the requirements on the computing power of both parties, and on the load and involvement of a trusted third party (TTP). Besides, there is a need to provide mobile users with a protocol adequate for ad hoc scenarios, where only unreliable channels can be guaranteed, and where the CA may not be reachable. In this paper we propose a new version of the fair non-repudiation protocol proposed by Gürgens et al. in [Sigrid Gürgens, Carsten Rudolph, Holger Vogt, On the security of fair non-repudiation protocols, in: Colin Boyd, Wenbo Mao (Eds.), ISC, Lecture Notes in Computer Science, vol. 2851, Springer, 2003, pp. 193–207]. We show unfair scenarios that can appear if one party controls the communication among the TTP and the other party. We introduce notary agents, which play the TTP role, and run our fair non-repudiation protocol. Notary agents execute inside the smart card, and sign the protocol messages with the user’s private key on his behalf. Our approach enables the protocol to run on unreliable channels, disconnected from the CA.},

abstract = {Nowadays we can perform business transactions with remote servers interconnected to Internet using our personal devices. These transactions can also be possible without any infrastructure in pure ad-hoc networks. In both cases, interacting parts are often unknown, therefore, they require some mechanism to establish ad-hoc trust relationships and perform secure transactions. Operating systems for mobile platforms support secure communication and authentication, but this support is based on hierarchical PKI. For wireless communications, they use the (in)secure protocol WEP. This paper presents a WCE security enhanced architecture allowing secure transactions, mutual authentication, and access control based on dynamic management of the trusted certificate list. We have successfully implemented our own CSP to support the new certificate management and data ciphering.},
