본 논문은 IoMT(의료 사물인터넷) 환경에 적합한 경량 인증 프로토콜의 보안성을 분석하였다. 분석 결과, 형식적 분석에서 완전 순방향 보안 부재, 재전송 공격 취약성, 오프라인 비밀번호 추측, 중간자 공격 등의 주요 취약점을 식별하였다. 이를 해결하기 위해 본 연구에서는 일회성 키 교환, 안전한 난수 생성, 비밀번호 강화, 공개 키 인증 등의 개선 방안을 제안하였다. 제안된 기법들은 자원이 제한된 의료 기기 환경에서도 효율성을 유지하면 서 보안을 크게 강화하며, 보다 안전한 IoMT 인증 시스템 구축에 기여할 것이다.

This paper analyzes a lightweight authentication protocol tailored for Internet of Medical Things (IoMT) environments. Through formal analysis, we identify key vulnerabilities including the absence of perfect forward secrecy, susceptibility to replay attacks, offline credential guessing, and man-in-the-middle threats. To address these issues, we propose practical improvements such as ephemeral key exchange, secure nonce generation, password hardening, and authenticated key verification. These enhancements significantly strengthen the protocol’s security while maintaining efficiency, making it more suitable for resource-constrained medical devices and contributing to the advancement of secure IoMT authentication systems.

In this paper, the biometric data is transmitted in real time from the IoT environment is runoff, forgery, alteration, prevention of the factors that can be generated from a denial-of-service in advance, and the security strategy for the biometric data to protect the biometric data secure from security threats offer. The convenience of living in our surroundings to life with the development of ubiquitous computing and smart devices are available in real-time. And is also increasing interest in the IOT. IOT environment is giving the convenience of life. However, security threats to privacy also are exposed for 24 hours. This paper examines the security threats to biological data to be transmitted in real time from IOT environment. The technology for such security requirements and security technology according to the analysis of the threat. And with respect to the biometric data transmitted in real time on the IoT environment proposes a security strategy to ensure the stability against security threats and described with respect to its efficiency.
