A Novel Smart-Card Based Authentication Scheme Using Proactive Secret Sharing

Yuesheng Zhu, Bojun Wang, Cheng Cai
2016 International Journal of Computer and Communication Engineering  
Traditional smart-card oriented authentication schemes provide a secure method for authorized users to login a remote server through insecure networks.  ...  However, the authentication procedures become complicated with abovementioned enhancements, so these enhanced schemes are not practical solutions for the smart card based authentication system.  ...  These schemes above provide a method for the remote server to authenticate a user. Chun-Ta Li [13] proposed a mutual authentication scheme between two communication parties.  ...

Proving your location without giving up your privacy

Wanying Luo, Urs Hengartner
2010 Proceedings of the Eleventh Workshop on Mobile Computing Systems & Applications - HotMobile '10  
For example, they do not support the proactive gathering of location proofs, where, at the time of acquiring a location proof, a user does not yet know for which application or service she will use this  ...  Supporting proactive location proofs is challenging because these proofs might enable proof issuers to track a user or they might violate a user's location privacy by revealing more information about a  ...  Acknowledgements We thank the anonymous reviewers and our shepherd Ramón Cáceres for their helpful comments.

Refresh When You Wake Up: Proactive Threshold Wallets with Offline Devices

Yashvanth Kondi, Bernardo Magri, Claudio Orlandi, Omer Shlomovits
2021 2021 IEEE Symposium on Security and Privacy (SP)  
In particular we give a highly efficient tρ = 2 protocol to upgrade a number of standard (2, n) threshold signature schemes to proactive security with offline refresh.  ...  In this work we formulate the notion of refresh with offline devices, where any tρ parties may proactivize the system at any time and the remaining n − tρ offline parties can non-interactively "catch up  ...  They would also like to thank the anonymous reviewers for their feedback, which was useful in improving the paper.  ...

Secret interest groups (SIGs) in social networks with an implementation on Facebook

Alessandro Sorniotti, Refik Molva
2010 Proceedings of the 2010 ACM Symposium on Applied Computing - SAC '10  
Members exchange credentials that can be used inside the social network to authenticate upon friendship requests or to secure user-generated content.  ...  To this end we present a set of cryptographic algorithms leveraging on well-studied primitives, and we describe a java implementation of the framework for Facebook.  ...  An OSBE scheme allows two parties to share a key iff a predefined party among the two possesses a signature on an agreed-upon message.  ...

A Secure Voice Signature Based Lightweight Authentication Approach for Remote Access Control

Oladayo Olufemi Olakanmi, Aminat Shodipo
2019 International Journal of Advanced Network, Monitoring, and Controls  
The scheme extracts the user's voice signature as the hash of the MFCC parameters of the voice and unique passcode which is used for the authentication.  ...  However, this is quite difficult especially for any network that is characterised with low computation and energy, and relied on the third party for key management.  ...  VOICE SIGNATURE BASED AUTHENTICATION SCHEME FOR ACCESS CONTROL The voice signature based authentication scheme involves two phases; registration and authentication phases.  ...
