چکیده مقاله :
در اين مقاله ابتدا یک روش جدید رمزنگاری مبتنی بر هویت ارائه می‌گردد و نشان داده می‌شود در مقایسه با روش‌های پیشین دارای سربار محاسباتی کمتری است. در این راستا، روش مبتنی بر هویت پیشنهادی، شبیه‌سازی شده و نتایج حاصل با نمایندگان برتر رمزنگاری مبتنی بر هویت مورد مقایسه قرار می‌گیرد. سپس در ادامه پژوهش با استفاده از پروکسی رمزنگاری مجدد و روش رمز مبتنی بر هویت ارائه‌شده در این مقاله، یک سیستم سلامت الکترونیک ابری پیشنهاد می‌گردد. این سیستم علاوه بر فراهم‌کردن محرمانگی و افزایش قابلیت دسترسی، در کلیه مراحل راه‌اندازی، تولید کلید خصوصی، رمزگذاری، تولید کلید رمز مجدد، رمزنگاری مجدد و رمزگشایی دارای زمان اجرای کمتری است و منجر به کاهش هزینه محاسباتی و سربار ارتباطی فرایند رمزنگاری در سیستم سلامت الکترونیک می‌شود.
In this paper, a new method of identity-based encryption is first presented, and it is shown that there is less computational overhead than previous methods. In this regard, the proposed identity-based encryption method is simulated, and the results are compared with the superior representatives of the identity-based encryption. Then, a cloud-based electronic health system (EHS) is proposed using the re-encryption proxy and the identity-based encryption method presented in this paper. In addition to providing confidentiality and enhancing accessibility, the system has a lower running time in the phases of setup, private key generation, encryption, re-encryption key generation, and decryption — this resulting in lower costs and overhead of the cryptographic process in the Electronics health system.
