Bezpečnostní analýza elektronického "Peer to Peer" platebního systému platformy Bitcoin

Abstract

Security Analysis "Peer-to-Peer" Electronic Cash System for the master thesis on the Bitcoin platform provides an overview of the security model of peer-to-peer cryptographic currencies. In this master thesis introduces Bitcoin and its design principles, as well as its cryptographic primitives. The focus of the work is analyzing Bitcoin security. It aims to develop a better understanding of how Bitcoin is secured by analyzing various attacking methods related to the system, their relationships and defense mechanisms in Bitcoin system design. We describe that cryptography used in Bitcoin is strong that cannot be breakable, but the system is not tolerant against attacked with computing power and attack by special machines connected to the network. However, lient-side attacks are much more severe because users are highly responsible in Bitcoin. This thesis look into detail of those attacks and explain about defense against them.
