Sistem Kriptokompresi Menggunakan Algoritma Asimetris Rabin-P dan Algoritma Lossless Compression Golbach Code

<p>The in line line with the development of information technology, information security must also be considered. Advances in information technology provide many advantages for the survival of human life, but the advantages offered by technology also cause losses such as data theft. Data originating from word processing documents is one form of document that is commonly used to store information, whether private or confidential. The security issues are one of the most important aspects in the world of information technology which is a human need in the era of globalization, for example document security. Therefore, document security is very necessary and must be protected from irresponsible parties, either when stored in storage or when distributed. In addition to the security aspect, the thing that needs to be considered is also about the storage media. Therefore, additional steps are needed to streamline the storage media by compressing the data that has been secured so that its size becomes smaller. In this study, we will combine cryptographic techniques and compression techniques called cryptocompression. The cryptocompression system in this research is applied by encrypting data in text files using the public key of the Rabin-p algorithm which will produce an encrypted text file. Then it is compressed using Goldbach Code lossless compression algorithm to reduce its size. From the results of this test, it is concluded that the cryptocompression system is able to maintain the confidentiality of information because it has been encrypted and can save more efficient storage space because it has been compressed first. Text files that have been encrypted and compressed can be returned to the original file through a decompression and decryption process according to the size and number of characters contained in the original text file.</p><p><strong>Keywords :</strong> <em>Cryptography, Compression, Cryptocompression, Rabin-p, Goldbach Code</em></p>

مراجعة طرق إخفاء البيانات العكسية في الصورة المشفرة

In the past few years, the world had witnessed a revolution in multimedia and Information Technology (IT) development and utilization. This results from the increase of the internet-based-communications including the transfer of the digital data in text files, audio, video, and/or image formats. Which is why, multimedia and IT became one of the crucial parts of people’s daily lives. There are numerous threats that target Image integrity, confidentiality, and authentication, therefore, the information security is a very important concept. The Reversible Data Hiding (RDH) is a data hiding method. RDH-Encrypted Image (RDH-EI) procedure which is working through embedding additional data to an image had emerged. Lately, the RDH-EI with the wide range is used, which is why, it has attracted the interest and focus of the employers as well as the academics. Thus, a survey that discusses previous researches will be carried out for the purpose of identifying the most significant (RDH-EI) approaches throughout the past five years. Several methods of RDH-EI with the different embedding rate, when its value is low (< 0.1 bpp), it is impossible to reconstruct the image without fault. Otherwise in the case where the embedding rate is high (>0.1 bpp), it is possible to obtain an image that is quite similar to the original image but it still needed for preprocessing step.

Automation of data processing of the results of the chemical experiment on modeling the production of synthetic rubber using Microsoft Excel

The article presents an approach to the processing of chemical experiment’s data using a Microsoft Excel software. Instead of storing the experiment data in text files, it is proposed to use a Microsoft Excel file of a certain structure. A macro has been developed to automate the process of transferring data from text files to a common file. The described approach can be applied when solving problems accompanied by storing a large amount of statistical data, which can be obtained as a result of natural or computational experiments. The macro has been tested on the data of a laboratory and numerical experiment on the synthesis of a styrene-butadiene copolymer. This copolymer is formed as a result of carrying out the process of copolymerization in continuous mode in a cascade of continuous stirred tank reactors. The results of the experiment are the characteristics of the formed product for each reactor of the cascade at the end of each hour of process modeling. Transferring data into a single file of a certain structure allows you to graphically present the results of the experiment and facilitates further analysis of the characteristics of the product being studied, depending on the formulation and process conditions.

SU‐C‐BRD‐03: Analysis of Accelerator Generated Text Logs for Preemptive Maintenance

Purpose:To develop a model to analyze medical accelerator generated parameter and performance data that will provide an early warning of performance degradation and impending component failure.Methods:A robust 6 MV VMAT quality assurance treatment delivery was used to test the constancy of accelerator performance. The generated text log files were decoded and analyzed using statistical process control (SPC) methodology. The text file data is a single snapshot of energy specific and overall systems parameters. A total of 36 system parameters were monitored which include RF generation, electron gun control, energy control, beam uniformity control, DC voltage generation, and cooling systems. The parameters were analyzed using Individual and Moving Range (I/MR) charts. The chart limits were calculated using a hybrid technique that included the use of the standard 3σ limits and the parameter/system specification. Synthetic errors/changes were introduced to determine the initial effectiveness of I/MR charts in detecting relevant changes in operating parameters. The magnitude of the synthetic errors/changes was based on: the value of 1 standard deviation from the mean operating parameter of 483 TB systems, a small fraction (≤ 5%) of the operating range, or a fraction of the minor fault deviation.Results:There were 34 parameters in which synthetic errors were introduced. There were 2 parameters (radial position steering coil, and positive 24V DC) in which the errors did not exceed the limit of the I/MR chart. The I chart limit was exceeded for all of the remaining parameters (94.2%). The MR chart limit was exceeded in 29 of the 32 parameters (85.3%) in which the I chart limit was exceeded.Conclusion:Statistical process control I/MR evaluation of text log file parameters may be effective in providing an early warning of performance degradation or component failure for digital medical accelerator systems.Research is Supported by Varian Medical Systems, Inc.
