Guess-then-Meet-in-the-Middle Attacks on the KTANTAN Family of Block Ciphers
The block cipher family for lightweight devices, KTANTAN, is analyzed in this paper. We propose a new cryptanalysis method which improves results of Meet-in-the-Middle attacks on K...

Alphabet-Independent Compressed Text Indexing
Self-indexes can represent a text in asymptotically optimal space under the k-th order entropy model, give access to text substrings, and support indexed pattern searches. Their ti...

Time-efficient spam e-mail filtering using n-gram models
In this paper, we propose spam e-mail filtering methods having high accuracies and low time complexities. The methods are based on the n-gram approach and a heuristics which is re...

Related-Key Impossible Differential Attacks on 8-Round AES-192
In this paper we examine the strength of AES against the related-key impossible differential attack, following the work of Jakimoski and Desmedt [12]. We use several additional obs...
