In this paper the newly proposed RMAC system is analysed and a generic attack is presented. The attack can be used to find one of the two keys in the system faster than by an exhaustive search. Also, a serious attack on RMAC used with triple-DES is presented.

Compositional data need a special treatment prior to correlation analysis. In this paper we argue why standard transformations for compositional data are not suitable for computing correlations, and why the use of raw or log-transformed data is neither meaningful. As a solution, a procedure based on balances is outlined, leading to sensible correlation measures. The construction of the balances...

The Advanced Encryption Standard (AES) was specified in 2001 by the National Institute of Standards and Technology [1]. The purpose is to provide a standard algorithm for encryption, strong enough to keep U.S. government documents secure for at least the next 20 years. Now AES will largely replace triple-DES for government use, and will likely become widely adopted for a variety of encryption n...

We describe a higher-order spectral analysis-based approach for detecting people by recognizing human motion such as walking or running. The periodic attribute of human motion lends itself to efficient spectral inspection. In the proposed method, the stride length is determined in every frame as the image sequence evolves. The bispectrum which is the Fourier transform of the triple correlation ...

BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...

Background The endometrial echopattern on the day of human chorionic gonadotropin (HCG) administration and its relationship to the outcome of pregnancy after assisted reproductive treatment (ART) cycles was analyzed, prospectively. MaterialsAndMethods This study conducted between 2013 to 2014. The endometrial pattern was evaluated prospectively on the day of administration of HCG in 280 ART cyc...

background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

introduction: the purpose of this study was to determine the in vitro antimicrobial ability against entrococcus (e.) faecalis of triple antibiotic paste and its components compared with calcium hydroxide mixtures . materials and methods: an agar well diffusion assay and mic method were used to determine the efficacy of the experimental medicaments in removing e. faecalis. medicaments were divid...

Pairwise nonisomorphic directed and hybrid triple systems can be generated by, respectively, directing and ordering twofold triple systems and using the automorphisms of the twofold triple systems for isomorph rejection. Using this approach directed triple systems of order up to 10 and hybrid triple systems of order up to 9 are classified. In particular, it turns out that the number of nonisomo...

As the Semantic Web (SW) is being automatically populated with large number of RDF triples scalability issues related to wide scale reasoning occur. We believe these difficulties are due to the use of global reasoning engines, which carry all the load of collecting and handling all relevant triples, and they can be alleviated by distributing the load of the reasoning amongst the meaningful enti...
