This study aims to conduct a cost-effectiveness analysis of three different anesthesia strategies,namely chatting while under local anesthesia(Chat-LA),total intravenous anesthesia(TIVA),and general anesthesia with laryngeal mask airway(GA-LMA),employed in transperineal magnetic resonance imaging(MRI)/ultrasound(US)fusion prostate biopsy(TP-MUF-PB).A retrospective study was conducted involving 1202 patients who underwent TP-MUF-PB from June 2016 to April 2023 at The First Affiliated Hospital of Soochow University(Suzhou,China).Clinical data and outcomes,including total costs,complications,and quality-adjusted life years(QALYs),were *** sensitivity and subgroup analyses were also ***-LA was found to be the most cost-effective option,outperforming both TIVA and ***,subgroup analyses revealed that in younger patients(under 65 years old)and those with smaller prostate volumes(<40 ml),TIVA emerged as a more cost-effective *** Chat-LA may generally be the most cost-effective and safer anesthesia method for TP-MUF-PB,personalization of anesthesia strategies is crucial,considering specific patient demographics such as age and prostate volume.

A Secure Mutual Authentication Protocol Based on Visual Cryptography Technique for IoT-Cloud

引用

Chinese Journal of Electronics 2024年第1期33卷 43-57页

作者： Brou Bernard Ehui chen chen Shirui WANG hua GUO jianwei LIU School of Cyber Sciences and Technology Beihang University State Key Laboratory of Software Development Environment Beihang University Sino-French Engineering School Beihang University Beihang Hangzhou Innovation Institute Yuhang

Because of the increasing number of threats in the IoT cloud, an advanced security mechanism is needed to guard data against hacking or attacks. A user authentication mechanism is also required to authenticate the user accessing the cloud services. The conventional cryptographic algorithms used to provide security mechanisms in cloud networks are often vulnerable to various cyber-attacks and inefficient against new attacks. Therefore,developing new solutions based on different mechanisms from traditional cryptography methods is required to protect data and users’ privacy from attacks. Different from the conventional cryptography method, we suggest a secure mutual authentication protocol based on the visual cryptography technique in this paper. We use visual cryptography to encrypt and decrypt the secret images. The mutual authentication is based on two secret images and *** user requests the ticket from the authentication server(AS) to obtain the permission for accessing the cloud services. Three shared secret keys are used for encrypting and decrypting the authentication process. We analyze the protocol using the Barrows-Abadi-Needham(BAN)-logic method and the results show that the protocol is robust and can protect the user against various attacks. Also, it can provide a secure mutual authentication mechanism.
