THERMAL SPRAYING AND HARD FACING

INTRODUCTION

Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface.

The feedstock (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame).

Thermal spraying can provide thick coatings (approx. thickness range is 20 micrometers to several mm, depending on the process and f ....etc

Abstract Engine anti-theft system is not only flexible and
convenient but also high-performance, high-efficient and highsecurity.
Based on the identity authentication principle of engine
anti-theft system, with the AES encryption algorithm theory, this
paper proposes the AES encryption methods and steps which are
appropriate for the identity authentication of engine anti-theft
system. It also designs the experimental program and obtains
good results.

Abstract - Encryption algorithms play a vital role in information
security systems. The study discovers the progress of Encryption
algorithms in terms of their diversity of applications. Some of the
Encryption algorithms have been developed to make transmission
and storage of data more secured and confidential. Different levels
of securities are offered by different algorithms depending on how
difficult is to break them. If it is difficult to recover the plain text in
spite of having substantial amount of cipher text then an algorithm

HARDWARE IMPLEMENTATION AND ANALYSIS OF MD5

Abstract:- Hardware implementation aspects of the MD5 hash algorithm are discussed in this paper. A general architecture for MD5 is proposed and several implementations are presented. An extensive study of effects of pipelining on delay, area requirements and throughput is performed, and finally certain architectures are recommended and compared to other published MD5 designs. Hash algorithms are used widely in cryptographic protocols and Internet communication in general. Several widely used hash ....etc

Abstract:
Sensors are tiny computers with limited computational capability and physical resources. The implementation of secure protocols for sensor network is a big challenge. In order to provide high security for sensor networks, it is very important to choose a small, efficient and effective encryption algorithm as a security primitive. The TEA (Tiny Encryption Algorithm) is an efficient algorithm that requires little memory and resources. These features make the TEA a good candidate for security mechanism for sensors. In this paper we desc ....etc
