The security flaws of a direct anonymous attestation scheme proposed by He et al. was analyzed, and the result shows that the authentication protocol of the scheme is vulnerable to reply attacks and platform masquerading attacks when being used for remote attestation. An improved direct anonymous attestation authentication scheme with the involvement of key agreement was proposed to provide the property...
Radio Frequency Identification (RFID) technologies have been standardized and commercialized, but privacy problem is a major challenge due to no ideal solution used in RFID system. We propose an efficient authentication protocol conforming to the EPCglobal standard for RFID security system to solve the privacy problem such as tracing and eavesdropping. Firstly we provide a comprehensive discussion...
While log data are being increasingly used as digital evidence in judicial disputes, the extent to which existing secure logging protocols used to collect log data fulfill the legal requirements for admissible evidence remain largely unclear. We elucidate the necessary secure requirements for digital evidence and extensively survey the state of the art secure logging protocols,thereby demonstrating...
As authentication provides crucial online identity, it is the basis of data security. In this paper, a session based authentication is proposed and the long unique un-guessable session identifier is used as a parameter of an authentication token. It has the advantages of one-timeness, short-lived and no prior knowledge requirement. The session model is established with detailed implementation of communication...
This paper proposes a new security protocol with satisfying the lightweight requirements of the security of RFID system - A Minimalist Mutual Authentication Protocol for RFID System Based on EPC C1G2 Standard. The scheme makes sufficiently use of the limited resources of RFID system to encrypt, decrypt and implement mutual authentication between readers and tags, Then the paper gives qualitative analysis...
