As smartphones are generalized, various technologies and services have been introduced and are in wide use. From simply using calling or texting services, Internet banking and transaction system that require sensitive personal information emerged. Google’s Android, one of the representative OS of smartphones, was developed based on an open source, having various weaknesses and exposed to securi...

Metal ceramic restorations were considered the gold standard as reliable materials. Increasing demand for esthetics supported the commercialization of new metal free restorations. A growing demand is rising for zirconia prostheses. Peer-reviewed articles published till July 2013 were identified through a Medline (Pubmed and Elsevier). Emphasizing was made on zirconia properties and applications...

Object-oriented database systems began developing in the mid-80’s out of a necessity to meet the requirements of applications beyond the data processing applications which were [are] served by relational database systems. This paper serves as an overview on the achievements of object-oriented database technology so far, and also discusses the weaknesses that have to be yet resolved by the objec...

Web-based mechanisms, often mediated by malicious JavaScript code, play an important role in malware delivery today, making defenses against web-borne malware crucial for system security. This paper explores weaknesses in existing approaches to the detection of malicious JavaScript code. These approaches generally fall into two categories: lightweight techniques focusing on syntactic features s...

A significant number of attacks on systems are against the non-cryptographic components such as the human interaction with the system. In this paper, we propose a taxonomy of human-protocol interaction weaknesses. This set of weaknesses presents a harmonization of many findings from different research areas. In doing so we collate the most common human-interaction problems that can potentially ...

A recent article in TREE [1] presented a heavily documented review of experimental evolution, addressing three major issues: main questions and applications; experimental design and study systems; and caveats and limitations. Here, we comment on the latter issue. The soundness of a scientific method depends on not only its adequacy relative to the specific goals, but also the relative suitabili...

We propose a new attack on Feistel ciphers with a non-surjective round function. CAST and LOKI91 are examples of such ciphers. We extend the attack towards ciphers that use a non–uniformly distributed round function and apply the attack to CAST.
