Abstract

As blockchain technology develops, encryption for blockchain blocks is also becoming more important. Encryption in the blockchain is used to secure the identity of the person who created the transaction and to prevent manipulation of information in the past block. However, increasing the security of encryption decreases the speed of block creation, one of the biggest drawbacks of the blockchain. Therefore, in this paper, we propose a method to minimize the performance of the current OTP and the degradation of the blockchain by comparing the status and performance of OTP used in the blockchain.

블록체인 기술이 발전함에 따라 블록체인 블록에 대한 암호화 또한 중요시되고 있다. 블록체인에서의 암호화는 트랜잭션을 생성한 사람의 신원보안과, 과거 블록의 정보를 조작 할 수 없도록 하게 이용된다. 하지만 암호화의 보안성을 증가시키면 블록체인의 가장 큰 단점중의 하나인 블록생성의 속도가 감소하게 된다. 따라서 본 논문에서는 블록체인에 사용되는 OTP의 현황과 성능을 비교하여 현재 OTP의 성능 및 블록체인의 성능저하를 최소화 할 수 있는 방안을 제시한다.
