Abstract :
با گسترش فناوری اطلاعات، سیستم‌های سلامت الکترونیکی به‌عنوان یک رویکرد رایج برای ثبت اطلاعات پزشکی بیماران استفاده می‌شوند. با توجه به این‌که اطلاعات پزشکی، دارایی ضروری افراد و نظام سلامت هستند، نگرانی‌های زیادی پیرامون اشتراک‌گذاری امن و حفظ حریم خصوصی این اطلاعات وجود دارد. در این مقاله، ما یک روش جدید رمزگذاری مبتنی بر شناسه را به‌کمک جفت‌‌سازی دوخطی برای اطمینان از محرمانگی داده‌های بیماران و حریم خصوصی آن‌ها در سیستم‌های سلامت ابری پیشنهاد می‌کنیم. این طرح، احراز هویت را برای کاربران با استفاده از مکانیسم‌های چالش-پاسخ فراهم می‌کند. علاوه بر این، طرح پیشنهادی با استفاده از بلاک‌چین، یکپارچگی و کنترل دسترسی دقیق را برای داده‌های اشتراکی تضمین می‌کند. درستی پروتکل پیشنهادی تأیید می‌شود و امنیت آن به‌طور رسمی در مدل استاندارد اثبات خواهد شد. نتایج حاصل از پیاده‌سازی در نرم‌افزار جاوا نشان می‌دهد که طرح پیشنهادی، سربار محاسباتی را در مقایسه با روش‌های مشابه قبلی کاهش می دهد.
