초록
블록체인은 증가하는 트랜잭션 수와 사용자 수로 인해 많은 계산과 네트워크 통신을 지연시켜 실시간 처리에 효율적이지 않다. 이를 해결하기 위하여, 본 연구는 클라우드 프락시 서버를 제안하므로 적법한 사용자가 블록체인을 사용할 뿐만 아니라 네트워크 지연 시간을 단축할 수 있다. 블록체인 트랜잭션 진행을 위해, 블록체인 복사 서버에서는 트랜잭션 관련 모든 데이터를 검증하지만 클라우드 프락시 서버는 간단한 영지식 증명 알고리즘으로 적법한 사용자를 검증하므로 효율적인 블록체인 실시간 처리가 가능하다. 클라우드 프락시 서버는 블록체인 사용자의 키 쌍을 등록 받아 제안한 영지식 증명으로 적법한 사용자를 검증할 수 있는 블록체인 익명성, 보안성, 확장성을 지원할 수 있다. 제안 연구 분석에서 블록체인 기반 클라우드 프락시 서버는 이전 연구들과 비교하여 네트워크 지연 시간을 단축시키고, 클라우드 프락시 서버의 키 프로세싱은 이전 연구들보다 키 계산 비용을 감소시킨다.
Abstract
Blockchains are not efficient for real-time processing because the growing number of transactions and users delays many computations and network communications. This study proposes a cloud proxy server, so that legitimate users can use blockchain as well as reduce network latency. To proceed with a blockchain transaction, the blockchain copy server verifies all transaction-related data, but the cloud proxy server verifies legitimate users with a simple zero-knowledge proof algorithm, enabling efficient blockchain real-time processing. The cloud proxy server can support blockchain anonymity, security, and scalability that can verify legitimate users with the proposed zero-knowledge proof by receiving the registered key pair of the blockchain user. In the proposed research analysis, blockchain-based cloud proxy server reduces network latency compared to previous studies and key processing on cloud proxy servers reduces the cost of key computation compared to previous studies.
