The development of communication technology has brought changes to various environments. The evolution from 3G to 4G Long-Term Evolution (LTE) was mainly aimed at improving communication speed. However, the evolution from 4G LTE to 5G New Radio (NR) is not aimed at improving speed alone. In addition to the existing communication types, 5G aims to improve communication to support the Internet of Things (IoT), media, and complex content to which things are connected. In such environments, point-to-point communication has a very inefficient structure to allow content providers to transmit data to many content users. In the 5G era, content providers must distribute content to numerous users, and in this process, they need to protect the content. Multireceiver encryption (MRE) is an encryption technology developed for this purpose. MRE allows multiple recipients to decrypt data using their own private key with single encryption of a data provider. With this technology, even if the number of data recipients is 100,000 or 1,000,000, data can be distributed with single encryption. Therefore, while using the existing 1 : 1 encryption method, it is possible to solve the problem of inefficiency in performing encryption for each recipient. However, existing proposed MREs can cause key escrow problems and partial key verification problems. Furthermore, the privacy issues identifying the recipient may arise because anonymity is not available to the recipient. In addition, it is necessary to ensure a fair decryption process for all recipients which a legitimate user cannot decrypt. In this study, we attempted to address these problems, and through our model, it is possible to distribute the data more securely and efficiently in a 5G environment.

使用 5G 通信在联网汽车环境中为多个接收器分配数据

通信技术的发展给各种环境带来了变化。从 3G 到 4G 长期演进 (LTE) 的演进主要是为了提高通信速度。然而，从 4G LTE 到 5G 新无线电 (NR) 的演进并不仅仅旨在提高速度。除了现有的通信类型外，5G 还旨在改进通信以支持物联网 (IoT)、媒体和物联网的复杂内容。在这样的环境中，点对点通信的结构非常低效，以允许内容提供商向许多内容用户传输数据。5G时代，内容提供商必须将内容分发给众多用户，在这个过程中，他们需要对内容进行保护。多接收器加密 (MRE) 是为此目的而开发的加密技术。MRE 允许多个接收者使用他们自己的私钥和数据提供者的单一加密来解密数据。有了这项技术，即使数据接收者的数量是 100,000 或 1,000,000，也可以通过单一加密来分发数据。因此，在使用现有的1:1加密方式的同时，可以解决对每个接收者进行加密效率低下的问题。然而，现有的 MRE 可能会导致密钥托管问题和部分密钥验证问题。此外，由于收件人无法匿名，因此可能会出现识别收件人的隐私问题。此外，需要确保对合法用户无法解密的所有收件人进行公平的解密过程。在这项研究中，我们试图解决这些问题，并通过我们的模型，
