Variations on the Themes of Message Freshness and Replay { or the Di culty in Devising Formal Methods to

چکیده
We survey the variations on the choice and the usage of freshness identiiers, and the various forms of replay attack. Besides helping to clarify the important concepts of freshness and replay, this exercise demonstrates the potential complexity in devising formal methods to analyze cryptographic protocols.

Timed Models for Protocol Security
The notion of time is prerequisite for describing and verifying the security proper ties of key management protocols Without it properties relating to the expiration of keys and the freshness of messages and nonces cannot be formulated Recently Burrows Abadi and Needham proposed a formal system for protocol veri cation which includes an ability to reason about time In essence their Logic of Au ...
متن کاملTimestamps for Network Authentication Protocols Revisited
In network security protocols, the freshness and uniqueness of a particular protocol-run provide a strong defense against replay attacks. These two properties are incorporated into a protocol interaction by the use of time-variant parameters such as nonces, random numbers, sequence numbers and timestamps. Many of the network authentication protocols can be classi ed into two main streams by the...
متن کاملInterference Mitigation of Replay Attacks in GPS Receiver using of Finite Impulse Response Filter
The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...
متن کاملFreshness and Reactivity Analysis in Globally Asynchronous Locally Time-Triggered Systems
Critical embedded systems are often designed as a set of real-time tasks, running on shared computing modules, and communicating through networks. Because of their critical nature, such systems have to meet timing properties. To help the designers to prove the correctness of their system, the real-time systems community has developed numerous approaches for analyzing the worst case times either...
