Secure Set-Based Policy Checking and Its Application to Password Registrationr enforcement is often in conflict with user privacy. In order to check the satisfiability of a policy, a server usually needs to collect from a client some information which may be private. In this work we introduce the notion of secure set-based policy checking (SPC) that allows the server to veri

,: Efficient Partial Keyword Search on Encrypted Dataa client who has the corresponding secret key can generate search queries (say, trapdoor) in order to search for the encrypted data on the server. In this paper, we focus on . in the public key setting in order to enhance usability. We call this “Searchable Encryption with Partial Matching (SEPM)”.

Such passwords might also be harder to guess, thus possibly providing higher security..Given these potentially unique advantages, we set out to closely investigate the security of

iDeFEND: Intrusion Detection Framework for Encrypted Network Dataption is used to protect the confidentiality of network data. When end-to-end encryption is applied, Network Intrusion Detection Systems are blind and can not protect against attacks. In this paper we present iDeFEND, a framework for inspecting encrypted network data without breaking the security mo

Practical Password-Based Authentication Protocol for Secret Sharing Based Multiparty Computationeen put into practice. Authentication of clients is one critical mechanism for implementing SS-based MPC successfully in practice. We propose a password-based authentication protocol for SS-based MPC. Our protocol is secure in the presence of secure channels, and it is optimized for practical use wi
