Journal ArticleDOI
A survey of video encryption algorithms
Fuwen Liu,Hartmut Koenig +1 more
TL;DR: A complete survey of the representative video encryption algorithms proposed so far is given and it is shown that each scheme has its own strengths and weaknesses and no scheme can meet all specific requirements.
Proceedings ArticleDOI
A novel encryption algorithm for high resolution video
Fuwen Liu,Hartmut Koenig +1 more
TL;DR: A novel video encryption algorithm, called Puzzle, is presented, to encrypt video data in software that is fast enough to meet real-time demands and provides a sufficient security.
Proceedings ArticleDOI
Location-independent fall detection with smartphone
TL;DR: This paper presents a location-independent fall detection method implemented as a smartphone application for an inconspicuous use in nearly every situation of the daily life and applies a modular threshold-based algorithm which uses the acceleration sensor with moderate energy consumption.
Book ChapterDOI
Cryptanalysis of a SIP authentication scheme
Fuwen Liu,Hartmut Koenig +1 more
TL;DR: A SIP authentication scheme based on elliptic curve cryptography (ECC) that claimed to provide higher security than other schemes is still vulnerable to off-line dictionary and partition attacks.
Book ChapterDOI
Improving the efficiency of misuse detection
TL;DR: This paper discusses analysis techniques of IDSs used today and introduces a couple of optimizing strategies, which exploit structural properties of signatures to increase the analyze efficiency and compares them with currently deployed misuse detection techniques.
