RFID ownership transfer protocols (OTPs) transfer tag ownership rights. Recently, there has been considerable interest in such protocols; however, guaranteeing privacy for symmetric-key settings without trusted third parties (TTPs) is a challenge still unresolved. In this paper, we address this issue and show that it can be solved by using channels with positive secrecy capacity. We implement t...

In order to solve the excessive computation and storage requirement arising due to the frequent sensor nodes movement in WSN, a new public key has been proposed based on ECC key agreement protocol. The mutual authentication and agreement on a session key can be realized between users, or between user and a network server in WSN. This protocol adopts ECC techniques to consult session keys and AE...

The session initiation protocol (SIP) is a powerful signaling protocol that controls communication on the Internet, establishing, maintaining, and terminating the sessions. The services that are enabled by SIP are equally applicable in the world of mobile and ubiquitous computing. In 2009, Tsai proposed an authenticated key agreement scheme as an enhancement to SIP. Very recently, Arshad et al....

Regenerating codes based on the approach of interference alignment for wireless interference channel achieve the cut-set bound for distributed storage systems. These codes provide data reliability, and perform efficient exact node repair when some node fails. Interference alignment as a concept is especially important to improve the repair efficiency of a failed node in a minimum storage regene...

In this paper, we consider a transmit power allocation problem for secure transmission in multi-hop decode-and-forward (DF) full-duplex relay (FDR) networks, where multiple FDRs are located at each hop and perform cooperative beamforming to null out the signal at multiple eavesdroppers. For a perfect self-interference cancellation (PSIC) case, where the self-interference signal at each FDR is c...

The Strong Stackelberg Equilibrium (SSE) has drawn extensive attention recently in several security domains. However, the SSE concept neglects the advantage of defender’s strategic revelation of her private information, and overestimates the observation ability of the adversaries. In this paper, we overcome these restrictions and analyze the tradeoff between strategic secrecy and commitment in ...

Recall that in the last lecture we discussed cryptographic security in the symmetric setting. The typical arrangement is that Alice and Bob share a common key that they use for encryption and decryption. This shared secret creates an distinction between the communicating parties (Alice and Bob) and the adversarial eavesdropper (Eve). The goal in this setting is to ensure that without the shared...

Abstract Smart city can improve the efficiency of managing assets and resources, optimize urban services quality citizens’ life. Wireless sensor networks (WSNs) solve many problems in smart city, such as transportation, healthcare energy. However, security privacy are biggest challenges for WSN. Recently, Banerjee et al. proposed a security-enhanced authentication key agreement scheme WSN, but ...

The standardized Authentication and Key Agreement protocol for 5G networks (5G AKA) have several security privacy vulnerabilities. In this paper, we propose a novel authentication key agreement beyond that is compatible with the AKA. Our has properties, e.g., perfect forward secrecy, resistance against linkability attacks, protection malicious SNs. Moreover, both user identity secrecy are handl...
