VHDL design of a DES encryption cracking system

This thesis illustrates the design of a chip to crack a message encrypted with Digital Encryption Standard (DES). VHSIC Hardware Description Language (VHDL) is used to describe the system. Part of the design criteria of the system is to provide a scalable and reconfigurable set of DES building blocks in VHDL. In order to provide this, a modular design with a pipeline architecture is employed. This system could be synthesized to produce actual hardware in either an ASIC or FPGA part. Simulations using Synopsys with Actel\u27s 3200DX FPGA library demonstrate that the design could be run at over 16Mhz. Because a pipelined architecture is employed which retires one key every clock cycle the chip would be able to test over 1 6 million keys per second. This is a vast improvement over current software-only based approaches that achieve speeds of 1 to 2 million keys per second on expensive high-end micro-processors

A Study of Required Educational Preparation and Role of Entry Level Public Relations Practitioners: A National Educator and Practitioner Perspective

The public relations profession is in a constant state of change, and it doesn\u27t have a clear definition. Without having a clear understanding of public relations, it is difficult to know exactly how to prepare college students who aspire to become public relations practitioners for the profession. Moreover, there is only limited public relations research and literature regarding the required educational preparation and role of entry-level practitioners. Therefore, due to the limited literature, this study was conducted, in general, to learn more about the required educational preparation and role of entry-level PR practitioners and, specifically, to test the following three hypotheses. H1: Skills of expression, writing and interpersonal communication, will be ranked as the two most required skills for obtaining an entry level PR position and the top two functions most performed by entry-level PR practitioners by both practitioners and educators. H2: Skills of expression, writing and interpersonal communication, will be ranked as the top two skills to be taught to aspiring entry-level PR practitioners by both practitioners and educators. H3: Subjects directly teaching skills of personal expression, writing an public speaking, will be ranked as the two most valuable subjects to be taught to aspiring entry-level practitioners by both practitioners and educators. On a national scale, 200 practitioners and 200 educators were surveyed in four general areas: 1) skill requirements to obtain entry-level PR employment; 2) entry-level PR functions performed; 3) PR skills to be taught in college; and 4) PR-affiliated subjects to be taught in college. Sixty practitioners and 28 educators responded within the given time frame. Overall, the results clearly indicate writing to be the most important skill requirement, function performed and skill to be taught, and newswriting followed with being the number one subject to be taught. However. statistically significant differences were still found between educator and practitioner views with regard to \u27skill requirements\u27 and \u27functions performed\u27 for answers ranked lower than writing. For skill requirements, practitioners indicated an importance of interpersonal communication with the majority (66%) of practitioners ranking it either first or second. The majority of educators ranked interpersonal communication third or lower creating a statistical difference at the .002 level. For functions performed, educators and practitioners were found again to have significant differences (.01) in how they ranked the importance of interpersonal communication. Practitioners, more than educators, believe interpersonal communication is more often a function of entry-level practitioners. Only four percent of educators indicated interpersonal communication is the number one function while 29 percent of practitioners believe it is the function most often performed. More educators, seven percent, actually ranked it fifth (or last) rather than first

Presidential Address - The Academy of the State and the State of the Academy

Our experimentation with the arrangement of the Academy program this year, largely due to the insight and initiative of Dr. Don Lewis of the State University of Iowa, and ably forwarded by Dr. Sherwood Tuttle and others from our host institution, seems to have been most successful if one can judge from the results so far. This rearrangement of the program, placing the address of the president in juxtaposition with the business meeting, allows and indeed makes advisable a change in its character
