A comparison of circuit implementations from a security perspectiveSundström, Timmy January 2005 (has links)
<p>In the late 90's research showed that all circuit implementations were susceptible to power analysis and that this analysis could be used to extract secret information. Further research to counteract this new threat by adding countermeasures or modifying the nderlaying algorithm only seemed to slow down the attack.</p><p>There were no objective analysis of how different circuit implementations leak information and by what magnitude.</p><p>This thesis will present such an objective comparison on five different logic styles. The comparison results are based on simulations performed on transistor level and show that it is possible to implement circuits in a more secure and easier way than what has been previously suggested.</p>

There were no objective analysis of how different circuit implementations leak information and by what magnitude. This thesis will present such an objective comparison on five different logic styles.

Právní postavení podnikatelů v sociálním zabezpečení / Legal capacity of entrepreneurs in the social securityHromádková, Jana January 2008 (has links)
This graduation thesis describes the legal capacity of entrepreneurs in the social security in Czech Republic and in Germany. The thesis focuses on circumscription of rights and duties of self-employed and their distinction to those of employees. With regard to the extensity of the described issue does the essay not cover the status of entrepreneur as an employer. Beside the account of the social security system and its scheme records this thesis the distinct conception of this area in both mentioned countries. Furthermore the essay compares the social security frameworks in the Czech Republic and in Germany. At the end this diploma paper contains their general consistent and different attributes and possible reasons of the unlike conception.
