نویسندگان
چکیده
We present a reduction semantics for the LYSA calculus extended with session information and a static analysis for it. If a protocol passes the analysis then it is free of replay attacks.

Complexity of Checking Freshness of Cryptographic Protocols
Freshness is a central security issue for cryptographic protocols and is the security goal violated by replay attacks. This paper is the first to formally define freshness and its attacks based on role instances and the attacker’s involvement, and is the first work to investigate the complexity of checking freshness. We discuss and prove a series of complexity results of checking freshness in s...
متن کاملA Formal Analysis for Capturing Replay Attacks in Cryptographic Protocols
We present a reduction semantics for the LYSA calculus extended with session information, for modelling cryptographic protocols, and a static analysis for it. If a protocol passes the analysis then it is free of replay attacks and thus preserves freshness. The analysis has been implemented and applied to a number of protocols, including both original and corrected version of Needham-Schroeder p...
متن کاملVariations on the Themes of Message Freshness and Replay { or the Di culty in Devising Formal Methods to
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.
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...
متن کاملFreshness-Preserving Non-Interactive Hierarchical Key Agreement Protocol over WHMS
The digitization of patient health information (PHI) for wireless health monitoring systems (WHMSs) has brought many benefits and challenges for both patients and physicians. However, security, privacy and robustness have remained important challenges for WHMSs. Since the patient's PHI is sensitive and the communication channel, i.e., the Internet, is insecure, it is important to protect them a...
