Abstract

Serial number of operating system windows 7 needs to be safeguarded, so can’t be used by the others. Security of the data can use by modern cryptography such as Vernam Cipher methods and classic cryptography such as Caesar Cipher methods. The security level both of this method depends on the keywords used and it will difficult to crack if the random key is used more and more. To get a random key, we can take from chaos of Lorenz equations as key-generator for encryption and description. Before utilizing chaos in the Lorenz equations, we have to find the maximum t (time) for the inverse problem solution to fit with the forward problem solution. We can use Runge-Kutta method in the Lorenz equations for forward problem solution and inverse problem solution. The solution of integral that obtained by the Runge-Kutta method can be searched by Trapezoidal method. The result of Runge-Kutta solution and Trapezoidal will be used as key-generator for encryption and description. In the simulations performed, the best orde in Runge-Kutta method is 4 and t max is 2. The encryption key is used as the initial condition of Lorenz equation, then the result is integrable by the Trapezoidal method. The result of orde 4 from Runge-Kutta method and Trapezoidal method used as a key-generator.  Application of Lorenz equation as key-generator for encryption and decryption, may change the cryptography algorithms of symmetric to be asymmetric.

Abstract

PT. Pharmacy X is one of Indonesia’s best-regarded manufactures of ethical medicine. It also manufactures “Naspro”, then well-known analgesic. As one of the companies which had stood since 1948 in the era of trace competition today, PT. Pharmacy X seeks to maintain and even more improve the quality of the products it produces so that it can survive and be able to develop products up to a better level again. For this matter, a decision taken by a leader of great influence on the success of an organization to achieve its goals, and it needs a proper method to analyze the objective factors that influence the success or failure in achieving that goal. Methods of Critical Success Factors (CSF) and CSF analysis is used by PT Pharmacy X to interpret the objects more clearly, to define the activities, and carried out every information’s needed. CSF can be determined if the objective or the direction and objectives of the organization have been identified. Destination PT. Pharmacy X is entered in 60 large pharmaceutical company in IMS-ITMA version. In addition to CSF, Value Chain analysis is also used in line with the CSF analysis that is useful to identifying the most critical processes, and provide a focus on achieving goals through actions or the most appropriate process to be implemented. The main activity is the most important factor in realizing the goal of PT. Pharmacy X, such as material ordering, forecasting sales, orders received from distributors, production processes, delivery of goods to a distributor, create demand, sales monitoring, evaluation and monitoring of stock sales.
