  • 본 논문은 블록체인에서 사용 중인 디지털서명을 국내외 동향으로 분석하여 향후 기존 디지털서명 기술이 새로운 대안의 디지털서명으로 대체될지 전망을 분석하였다. 디지털서명의 국내외 동향은 해시함수, 타원곡선, 디지털서명 알고리즘 등으로 구별하여 파악하였다. 디지털서명의 해외 동향에서는 ECDSA 외에 몇몇 새로운 알고리즘 도입이 진행 중에 있었지만 국내 동향에서는 단 하나의 사례도 찾기 힘들 정도로 여전히 대부분 업체에서는 ECDSA를 사용 중에 있었다. 아직까지 국내에서는 ECDSA의 채택률이 압도적이지만 해외에서는 조금씩 새로운 디지털서명을 채택 중에 있었다. 향후에는 ECDSA의 채택률이 줄어들고 새로운 디지털서명의 채택률이 올라갈 것으로 예상된다.

  • South Korea is a nation highly reliant on virtual water imports, which raises concerns of water crisis and food crisis at the national level. Virtual water and water footprint studies that consider the environment, social, and economic issues have been consistently addressed. However, there is a lack of Korean research, so the calculation method and comparison analysis are greatly dependent on foreign research results. The calculation results for Korean domestic agricultural products have been released in earnest since 2014. Thus, there has been an increase in comparison studies using domestic virtual water and water footprint results. This study identified the Korean agricultural and livestock water footprint research direction to determine the citation relationship trends. Domestic and foreign research results were analyzed from Korean water footprint related literature from the past 10 years. Therefore, a citation relationship diagram was formed from the literature analysis results. Virtual water and water footprint related research performance are provided in the appendix so researchers can utilize the various information related to this field in the future. In addition, national strategy policy making is expected to be presented for effective water resources management.
