Research And Design Of Sinulation Terminal Based On Applet

This article introduces a Research and Design of a Applet of SSH simulation terminal worked in an virtual experimental system about learning Linux. First, this paper analyzes the evolution of the terminal and simulation terminal and introduces the function and defects of early simulation Telnet terminal. Next, introduces the concept of SSH simulation terminal and analysis of the origin of SSH protocol, the basic framework, realization process, the main features and software components. This paper also introduces the theory of computer security technology, and analyzes the RSA and public-key cryptosystem. Applet technology in the form of the simulation terminals, therefore, article from the perspective of technology, introduces the concept of Applet, method and grammatical features. Papers in the latter part introduces the implementation process of the simulation terminal and the component subsystems. In the final papers, gives the presentation of the characteristics and improvements of this simulation terminal.
