An authentication protocol is proposed which originates from the elements of the authentication protocols belonging to the HB-family and the protocols based on employment of pseudorandom number generators. Desired features of the proposed protocol have been achieved via combining the pseudorandomnes generated by a compact keystream generator, randomness and dedicated homophonic and error-correction...
In an overview paper called State of the Art: Embedding Security in Vehicles, Wolf et al. give a general state-of- the-art overview of IT security in vehicles and describe core security technologies and relevant security mechanisms. In this paper we show that a formal analysis of many of the related properties is possible. This indicates that many expected aspects in the design of vehicular security...
Anonymity and specifically sender anonymity have become essential requirements for many privacy-related applications (e.g. net counselling and whistle blowing). On the other hand, anonymity may be abused for various malicious activities (e.g. redistribution of copy-righted contents and illegal drug trading). In this paper, we address both by proposing protocols for authenticated anonymous communications...
One of the next promising generation networks is personal networks where a user can make ad-hoc networks with his/her personal devices. However, the present security mechanism does not consider at all what happens whenever a mobile node (device) is compromised, lost or stolen. Since a user may hold many different types of devices, the leakage of stored secrets sometimes results in the complete breakdown...
Network mobility introduces far more complexity than host mobility. Therefore, host mobility protocols such as Mobile IPv6 (MIPv6) need to be extended to support this new type of mobility. To address the extensions needed for network mobility, the IETF NEMO working group has recently standardized the network mobility basic support protocol in RFC 3963. However, in this RFC, it is not mentioned how...
