Password Protected Smart Card and Memory Stick Authentication against Off-Line Dictionary Attacks
We study the security requirements for remote authentication with password protected smart card. In recent years, several protocols for password-based authenticated key exchange have been proposed. These proto...

RandHyp: Preventing Attacks via Xen Hypercall Interface
Virtualization plays a key role in constructing cloud environments and providing services. Although the main jobs of the hypervisors are to guarantee proper isolation between domains and provide them services,...

Modeling Social Engineering Botnet Dynamics across Multiple Social Networks
In recent years, widely spreading botnets in social networks are becoming a major security threat to both social networking services and the privacy of their users. In order to have a better understanding of t...

A Novel Chaining Approach to Indirect Control Transfer Instructions
Both dynamic binary translation systems and optimization systems store the translated or optimized code in the software maintained code cache for reuse. The performance of the code cache is crucial. Translated...

An Evidence-Based Trust Assessment Framework for Critical Infrastructure Decision Making
The availability and reliability of large critical infrastructures depend on decisions made by hundreds or thousands of interdependent entities and, by extension, on the information that the entities exchange ...

Clustering Recommenders in Collaborative Filtering Using Explicit Trust Information
In this work, we explore the benefits of combining clustering and social trust information for Recommender Systems. We demonstrate the performance advantages of traditional clustering algorithms like k-Means and ...

To Release or Not to Release: Evaluating Information Leaks in Aggregate Human-Genome Data
The rapid progress of human genome studies leads to a strong demand of aggregate human DNA data (e.g, allele frequencies, test statistics, etc.), whose public dissemination, however, has been impeded by privac...

Linear Obfuscation to Combat Symbolic Execution
Trigger-based code (malicious in many cases, but not necessarily) only executes when specific inputs are received. Symbolic execution has been one of the most powerful techniques in discovering such malicious ...

A Role-Involved Conditional Purpose-Based Access Control Model
This paper presents a role-involved conditional purpose-based access control (RCPBAC) model, where a purpose is defined as the intension of data accesses or usages. RCPBAC allows users using some data for cert...

Preventing Collusion Attacks on the One-Way Function Tree (OFT) Scheme
The one-way function tree (OFT) scheme proposed by Balenson et al. is widely regarded as an efficient key management solution for multicast communication in large dynamic groups. Following Horng’s claim that the ...

A More Natural Way to Construct Identity-Based Identification Schemes
Constructing identification schemes is one of the fundamental problems in cryptography, and is very useful in practice. An identity-based identification (IBI) scheme allows a prover to identify itself to a pub...

An Improved Poly1305 MAC
In this paper, we propose an improved Poly1305 MAC, called IPMAC. IPMAC is a refinement of Poly1305 MAC shown by Bernstein. We use only one 16-byte key and one 16-byte nonce for IPMAC while Poly1305 MAC uses t...

Real Perfect Contrast Visual Secret Sharing Schemes with Reversing
The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlap** shadow images without additional computations. However, the contrast of r...

Adaptive Detection of Local Scanners
Network attacks often employ scanning to locate vulnerable hosts and services. Fast and accurate detection of local scanners is key to containing an epidemic in its early stage. Existing scan detection schemes...
