There are few approaches that attempt to add dynamicity to the structure of stream ciphers in order to improve their security level. SCDSP is a dynamic stream cipher that based on these approaches. It uses dynamic structure and parameters to increase the complexity of the cipher to improve its security level. The dynamic parameters are specified using bits from the secret key. In this paper, SCDSP is evaluated by conducting a performance and security analysis. Furthermore, a comparison between SCDSP and the seven winners of eSTREAM competition is performed. The results show that SCDSP is very promising for practical use.

Abstract In 2013, a new stream cipher was proposed in Antal, E.-Hromada, V.: A new stream cipher based on Fialka M-125, Tatra Mt. Math. Publ. 57 (2013), 101-118. Its design was inspired and motivated by a Soviet encryption machine Fialka M-125. The authors proposed three versions of the cipher with different inner state bit-lengths. They provided the design, software implementation on a personal computer and a preliminary statistical and performance analysis of the cipher. In this article we extend their work by implementing all three versions of the cipher on two different micro-controllers: EBV SoCrates evaluation board [Official SoCrates webpage (EBV SoCrates evaluation board), www.rockerboards.org] and STM32F407VG [Official STM webpage (STM32F407VG), www.st.com]. We evaluate the performance of all implementations on both platforms. We also investigate the possibilities of performing a simple power analysis of the implementation of the 8-bit version of the cipher implemented on STM32F407VG micro-controller. It stems from our experiments that we are able to determine a part of the secret key of the cipher by observing the power trace (power consumption) of the encryption/decryption process

Descriptive Method

Objectives of this study were analyze fish auction participant satisfaction to auction services in TPI Morodemak, analyze attributes effect, services that fit to service quality measurement, and analyzed fish auction participants perception to performance and importance for fish auction house Morodemak services. Used descriptive method and purposive sampling with 49 respondents consists of commercial fishmongers, traditional fishmongers, purse seine owners, and boat lift net owners as fish auction participant. Satisfication measurement used Customer Satisfication Index (CSI), Importance and Performance Analysis (IPA) and gap analysis. Results from this study were value CSI 20% (0.2) indicate the auction participants dissatisfied with the services provided, IPA show there are four attributes should be develop, two elements have not been completed based on measurement requirements of service satisfaction, gap value average -0.05 means the auction participants were not satisfied with the performance of TPI services because the performance value was lower than the importance value.

Personal Tax

The Tax Payer obidience in fulfiling their taxation obligation will be influenced a lot by the satisfaction level toward the service fiscus. The aim of this observation is to know the response of Tax Payer toward service quality through importance and performance. The population which become the object of this observation is the personal Tax Payer registered in Bogor Tax Service Office and the number of respondents taken as the sample are 100 respondents with Slovin formula. The analysis method used is descriptive analysis and importance-performance analysis.   The result of this observation will be able to be used as one of the input to Bogor Tax Service Office in improving the quality service and for the following observation, especially those who take the same object as the observation in order to improve the quality service to the Tax Payer based on the service of its working way which is felt less. Otherwise it is important for The Tax Payer, maintaining the good work or balancing the service quality based on the working way which is evaluated less important by The Taxe Payer, but has been done reasonably well or very well by The Service Office
