Abstract

A large amount of transactions are taking place through Blockchain. Among them, the proportion of transactions through smart contracts is increasing. Accordingly, problems such as vulnerability attacks on smart contracts and fraud using smart contracts are increasing. Through security audits of smart contracts, developers can discover and resolve vulnerabilities, and users can distinguish whether smart contracts are fraudulent. However, there are currently no regulations and standards for security auditing of smart contracts, so services that perform security auditing are uneven. In this paper, we analyze security audit trends for smart contracts and identify what services are being provided. We investigate what elements are analyzed from smart contracts, focusing on security audit reports. Also, investigate what vulnerabilities can be detected. Finally, we investigate quality indicators for smart contracts and visualization elements of design extraction. Through this, we hope to be able to find visualization elements specialized for smart contracts.

블록체인을 통해 많은 양의 거래가 일어나고 있다. 그중에서도 스마트 계약을 통한 거래의 비중이 커지고 있다. 이에 따라 스마트 계약에 대한 취약점 공격과 스마트 계약을 이용한 사기와 같은 문제점들도 증가한다. 스마트 계약에 대한 보안 감사를 통해 개발자는 취약점을 발견해 해결할 수 있고, 이용자는 스마트 계약의 사기 여부를 구분할 수 있다. 하지만 현재 스마트 계약에 대한 보안 감사에 대한 규정과 표준이 없으므로 보안 감사를 수행하는 서비스들이 불균일하다. 본 논문에서는 스마트 계약에 대한 보안 감사 동향을 분석하고 어떠한 서비스들이 제공되고 있는지 파악한다. 보안 감사 보고서를 중심으로 스마트 계약으로부터 어떠한 요소들을 분석하는지 조사한다. 또한 어떠한 취약점들을 검출할 수 있는지 조사한다. 마지막으로 스마트 계약에 대한 품질 지표와 설계 추출의 가시화 요소를 조사한다. 이를 통해 스마트 계약에 특화된 가시화 요소를 찾을 수 있을 것을 기대한다.
