New Colored Visual Secret Sharing Schemes
Ching-Nung Yang,Chi-Sung Laih +1 more
TL;DR: A new construction for the colored VSS scheme is proposed that can be easily implemented on basis of a black & white V SS scheme and get much better block length than the Verheul-Van Tilborg scheme.
Journal ArticleDOI
Malicious web content detection by machine learning
TL;DR: This study analyzes the characteristic of a malicious webpage systematically and presents important features for machine learning, and demonstrates that the proposed method is resilient to code obfuscations and can correctly determine whether a webpage is malicious or not.
Journal ArticleDOI
On key distribution management for conditional access system on pay-TV system
TL;DR: It is shown that the proposed complete scheme is efficient and suitable for a pay-TV system which provides both pay per channel (PPC) and pay per view (PPV) services and is also a flexible one for dynamic management.
Journal ArticleDOI
A Hop-Count Analysis Scheme for Avoiding Wormhole Attacks in MANET
TL;DR: Instead of detecting wormholes from the role of administrators as in previous methods, a new protocol is implemented, MHA, using a hop-count analysis from the viewpoint of users without any special environment assumptions.
Journal ArticleDOI
A new threshold scheme and its application in designing the conference key distribution cryptosystem
TL;DR: A new threshold scheme is presented, which is based on the definition of cross-product in an N -dimensional vector space, which provides a protection of property against problems such as abnegation incidents or betrayal incidents.
