Official Bitcoin System Security Analysis: Deep Diving
2008 Bitcoin creator Satoshi Nakamoto has announced the principles of decentralized cryptocurrency. Although this main work formed the basis for the Bitcoin network, it is not possible in the official aspects of the system’s safety. In recent years, various researchers and cryptographers have been trying to analyze the Bitcoin protocol more strictly. This article provides an official overview of the Bitcoin system security analysis.
Bitcoin Protocol Overview
The Bitcoin protocol is based on a combination of cryptographic primitives including:
: Using a bag features such as Sha-256 (Safe Mags Algorithm 256) to create a digital fingerprint of each block.
2.
3.
Official security analysis
The official security analysis of the Bitcoin protocol includes the creation of a mathematical model that changes the characteristics of the system, including its safety restrictions. This is usually done with devices such as an element breakthrough (such as COQ or LCF) and cryptography library (eg Opensl).
One of the best -known official Bitcoin protocol security analysis was carried out by Daniel Buchmann’s researcher in 2013. [1]. A combination of mathematical patterns used in Buchmann’s analysis, including:
* Cryptographic Protocols : A detailed description of cryptographic primitives used in Bitcoin protocols.
* Mathematical Modeling
: Creating a mathematical model that seized the characteristics of the system, including its safety restrictions.
Buchmann’s analysis has shown that the Bitcoin protocol is safe with this type of attack called the “double edition attack” [2]. Specifically, the analysis has shown that the Bitcoin employment mechanism is safe against the attacker that can reach all previous blocks and try to replace them in some way.
Another researcher David Chaum also conducted the official security analysis of Bitcoin Protocol in 2014. [3]. The Chaum analysis was focused on the use of zero knowledge certificates (ZKP) to justify the reliability and integrity of the transactions without disclosing the sensitive information about the sender or recipient.
Chaum analysis showed that ZKP -based solutions can be used to control safe and private transactions, even in malicious actors [4].
Challenges and restrictions
Although official security analysis has been carried out in various aspects of the Bitcoin protocol, many challenges and restrictions must be taken into account:
* Complexity : Bitcoin protocol is a complex system with many interacting components, making it difficult to create a comprehensive mathematical model.
* Lack of Standardization : The Bitcoin community has not yet accepted standardized cryptographic protocols or testing procedures that can make it difficult to compare the safety of different implementation.
* Protocol development : Because new features and improvements are added to the Bitcoin protocol, existing official analysis may become obsolete.
Conclusion
The official security analysis of the Bitcoin system is a promising area of research that ensures a strict mathematical system to understand the security features of the network. Although there are challenges and restrictions in this work, it indicates that cryptographic primitives can be safely used in the Bitcoin protocol.
