Authentication is the most important issue to control the home networks remotely. In this paper, a strong authentication and key agreement method for a smart home network system is presented. The proposed scheme uses a smart card which stores private information and performs cryptic operations. It also uses a modified 3GPP security system that is suitable for the home network. Our scheme provid...

Abstract : The cryptographic strength of an SP network depends crucially on the strength of its substitution boxes (S-boxes). In this paper we use the concept of information leakage to evaluate the strength of Sboxes and SP networks. We define a n equivalence class on n x n S-boxes that is invariant in information leakage. Simulation results for a 16x 16 SP network suggest that after a sufficie...

The U. S. Naval Research Laboratory's OPIE (Onetime Passwords In Everything) Software Distribution is an enhancement of Bellcore's S/Key 1.0 package. OPIE improves on S/Key in several areas, including FTP service with one-time passwords, and a stronger algorithm for generating one-time passwords. OPIE diverges from S/Key in select design decisions and in the behavior of certain programs. While ...

social health is important to be assessed as a dimension of health. the aim of study was to determine domains and sub-domains of individual social health of iranians.this study was carried out with a qualitative approach, using thematic content analysis. twenty five experts participated in interviews, using individual semi-structured interviews between november 2010 and june 2011.this data supp...

Genetic programming is an evolutionary optimization method that produces functional programs to solve a given task. These programs commonly take the form of trees representing LISP s-expressions, and a typical evolutionary run produces a great many of these trees. For this reason, a good tree-generation algorithm is very important to genetic programming. This paper presents two new tree-generat...

S-parameter characterization of high-speed interconnect components is prone to numerical, modeling, and/or measurement error due, in part, the sampled nature data. This a problem modern package design where extensive signal integrity simulations are required validate system's performance. article presents new method treating data criterion developed clearly state minimum number frequency points...

This paper focuses on nonparametric efficiency analysis based on robust estimation of partial frontiers in a complete multivariate setup (multiple inputs and multiple outputs). It introduces a-quantile efficiency scores. A nonparametric estimator is proposed achieving strong consistency and asymptotic normality. Then if a increases to one as a function of the sample size we recover the properti...

In this work we explore the phase diagram of binary Nb-S system from ambient pressures up to 250 GPa using $ab$ $initio$ evolutionary crystal structure prediction. We find several new stable compositions and phases, especially in high-pressure regime, investigate their electronic, vibrational, superconducting properties. Our calculations show that all materials, besides low-pressure phases pure...
