In this scheme, the two authenticated users can transmit two bits of classical information per cluster state, and its efficiency of the quantum communication is 1/3, which is approximately 1.67 times that of the previous protocol presented by Wang et al [Chin.

The present protocol uses Einstein-Podolsky-Rosen （EPR） pairs and polarized single photons in batches. A particle of the EPR pairs is retained in the sender＇s station, and the other is transmitted forth and back between the sender and the receiver, similar to the‘ping-pong＇ QSDC protocol. According to the shared information beforehand, these two kinds of quantum states are mixed and then transmitted via a quantum channel. The EPR pairs are used to transmit secret messages and the polarized single photons used for authentication and eavesdropping check. Consequently, because of the dual contributions of the polarized single photons, no classical information is needed. The intrinsic efficiency and total efficiency are both 1 in this scheme as almost all of the instances are useful and each EPR pair can be used to carry two bits of information.展开更多

Ten feasible sequence patterns of authentication protocol with TIP and 5 sequence patterns without TFP are gained. These gained sequence patterns meet the requirements for identity authentication, and basically cover almost all the authentication protocols with TFP and without TFP at present. All of the sequence patterns gained are classified into unilateral or bilateral authentication. Then, according to the sequence symmetry, several good sequence patterns with TFP are evaluated.

In order to solve this problem, an authentication handover mechanism under multi-SDN domain(AHMMD) is proposed in this paper. In AHMMD, firstly, when the mobility entity accesses the network for the first time, its identity and service attributes are authenticated by the flow authentication protocol, which is designed based on the asymmetric encryption key; secondly, when the mobility entity moves to the neighbor domain, the authentication information will be delivered from the current controller to the neighborhood controller through a security communication channel. In order to promote the efficiency, a handover time prediction algorithm is adopted in AHMMD. Experimental results based on our AHMMD prototype have shown that the handover delay decreases by 50% while the handover cost decreases by 60%.展开更多

The enhanced scheme requires proof of the possession of both a password and a snort card, and provides more security guarantees in two aspects： 1） it addresses the untmceability property so that any third party accessing the communication channel cannot link two authentication sessions originated from the same user, and 2） the use of a smart card prevents offiine attacks to guess passwords. The security and efficiency analyses indicate that our enhanced scheme provides the highest level of security at reasonable computational costs. Therefore, it is a practical authentication scheme with attractive security features for wireless sensor networks.展开更多

Recently, Wang et al. proposed an authentication and key agreement scheme preserving the privacy of secret keys and providing user anonymity. Later, Chang et al. indicated that their scheme suffers from two security flaws. First, it cannot resist DoS （denial-of-service） attack because the indicators for the next session are not consistent. Second, the user password may be modified by a malicious attacker because no authentication mechanism is applied before the user password is updated. To eliminate the security flaws and preserve the advantages of Wang et aL＇s scheme, we propose an improvement in this paper.展开更多

Instead,extra computation cost degraded the performance.They were still vulnerable to a variety of threats, such as smart card loss attack and impersonation attack, due to hidden loopholes and flaws. Even worse, user's identity can be parsed in insecure environment, even became traceable. Aiming to protect identity, a lightweight mutual authentication scheme is proposed. Redundant operations are removed,which make the verification process more explicit. It gains better performance with average cost compared to other similar schemes.Cryptanalysis shows the proposed scheme can resist common attacks and achieve user anonymity.Formal security is further verified by using the widely accepted Automated Validation of Internet Security Protocols and Applications(AVISPA) tool.展开更多

文摘The long authentication handover delay is the greatest challenge in multi-domain SDN environment. In order to solve this problem, an authentication handover mechanism under multi-SDN domain(AHMMD) is proposed in this paper. In AHMMD, firstly, when the mobility entity accesses the network for the first time, its identity and service attributes are authenticated by the flow authentication protocol, which is designed based on the asymmetric encryption key; secondly, when the mobility entity moves to the neighbor domain, the authentication information will be delivered from the current controller to the neighborhood controller through a security communication channel. In order to promote the efficiency, a handover time prediction algorithm is adopted in AHMMD. Experimental results based on our AHMMD prototype have shown that the handover delay decreases by 50% while the handover cost decreases by 60%.

文摘In order to relvedy the security weaknesses of a robust user authentication framework for wireless sensor networks, an enhanced user authentication framework is presented. The enhanced scheme requires proof of the possession of both a password and a snort card, and provides more security guarantees in two aspects： 1） it addresses the untmceability property so that any third party accessing the communication channel cannot link two authentication sessions originated from the same user, and 2） the use of a smart card prevents offiine attacks to guess passwords. The security and efficiency analyses indicate that our enhanced scheme provides the highest level of security at reasonable computational costs. Therefore, it is a practical authentication scheme with attractive security features for wireless sensor networks.

文摘When accessing remote services over public networks, a user authentication mechanism is required because these activities are executed in an insecure communication environment. Recently, Wang et al. proposed an authentication and key agreement scheme preserving the privacy of secret keys and providing user anonymity. Later, Chang et al. indicated that their scheme suffers from two security flaws. First, it cannot resist DoS （denial-of-service） attack because the indicators for the next session are not consistent. Second, the user password may be modified by a malicious attacker because no authentication mechanism is applied before the user password is updated. To eliminate the security flaws and preserve the advantages of Wang et aL＇s scheme, we propose an improvement in this paper.

文摘Many improved authentication solutions were put forward, on purpose of authenticating more quickly and securely.However, neither the overuse of hash function,or additional symmetric encryption, can truly increase the overall security. Instead,extra computation cost degraded the performance.They were still vulnerable to a variety of threats, such as smart card loss attack and impersonation attack, due to hidden loopholes and flaws. Even worse, user's identity can be parsed in insecure environment, even became traceable. Aiming to protect identity, a lightweight mutual authentication scheme is proposed. Redundant operations are removed,which make the verification process more explicit. It gains better performance with average cost compared to other similar schemes.Cryptanalysis shows the proposed scheme can resist common attacks and achieve user anonymity.Formal security is further verified by using the widely accepted Automated Validation of Internet Security Protocols and Applications(AVISPA) tool.
