Abstract

Today's payment systems are becoming unmanned and changing to a way of paying with kiosks. This has the advantage of convenient payment because consumers can select a menu and specify the number of products to be purchased with just a touch of the screen. However, from the point of view of system security, the actual kiosk system has various vulnerabilities. This can hijack the administrator account, gain system privileges, and perform malicious actions. In addition, it is exposed to a number of security threats, such as the possibility of wasting unnecessary resources by abnormally increasing the number of payments, and causing the device to fail to operate normally. Therefore, in this paper, if any node of a participant in the solana blockchain approves an incorrect fork, the stake of the voting nodes is deleted. Also, since all participants can see the transaction history due to the nature of the block chain, I intend to write a thesis on a system that improves the vulnerability of kiosk payments by separating the access rights through the private blockchain.

오늘날 결제 시스템이 무인화되면서 키오스크로 결제하는 방식으로 변화하고 있다. 이는 소비자가 화면 터치만으로 메뉴 선택 및 구매 제품 개수를 지정할 수 있어 결제가 편리하다는 장점을 가진다. 그러나 시스템 보안 측면에서 바라보면, 실재하는 키오스크 시스템은 다양한 취약점이 존재한다. 이는 관리자 계정을 탈취하여 시스템 권한을 획득하고, 악의적인 행위를 진행할 수 있다. 또한 결제 개수를 비정상적으로 증가하여 불필요한 자원을 낭비하고, 기기가 정상적인 작동이 불가하도록 진행되게 할 가능성이 존재하는 등 많은 보안 위협에 노출되어 있다. 따라서 본 논문에서는 solana 블록체인의 참여자의 어떠한 노드가 올바르지 않은 fork를 승인한다면, 투표한 노드들의 지분은 삭제된다는 점을 이용한다. 또한 블록체인의 특성상 거래내역을 참여자 모두 볼 수 있기 때문에, 프라이빗 블록체인을 통해 접근권한 부분을 분리해 두도록 하여, 키오스크 결제에 대한 취약점을 개선하는 시스템의 논문을 작성하고자 한다.
