Attribute-Based Encryption (ABE) is one of the public-key cryptographic techniques which enforces a new method of security through effective control of access on the data which is stored or communicated in encrypted form using a variety of user defined access restrictions. ABE is implemented in a fully-fledged computer system, such as smartphones or embedded devices and it can be also used to enhance the security of network communication. In Attribute-Based Encryption, the encryption key will be associated with a set of attributes and these attributes are useful in the decryption process as well. Encrypting the data for numerous receivers can also be done with ABE, in such a way that only those with the right permissions can decrypt it later. The ABE provides a high level of security due to the wide range of key based qualities that can be defined, and it is also flexible enough to be used in a variety of communication and storage situations. In Wireless Sensor Networks (WSNs), the information is transmitted through wireless links from the sensors to a central location called the sink node. The nodes present in WSN are required to carry out the task of monitoring the environments, gather the necessary data through sensing, encrypt them and send them to the sink node. Therefore, security is a major concern for wireless communication since data is transmitted via an open wireless channel that can be accessed by malicious intruders. In order to handle the security problem, we propose a new Attribute-Based Encryption and Trust Based Secure Routing Algorithm (ABE-TBSRA) strategy by combining bilinear pairing and Diffie Hellman encryption scheme with RSA algorithm to encrypt and secure the data at the sender-side itself. In addition, we propose a new trust-based security model that uses three types of trusts namely direct, indirect, and historical trust values for improving the security. The major advantages of this proposed encryption and trust based secure routing algorithm include the enhancements in security level as well as packet delivery ratio, reliability of transaction and also the network throughput with reduced energy consumption and delay.
基于属性的加密（ABE）是一种公钥加密技术，它通过使用各种用户定义的访问限制，对以加密形式存储或通信的数据进行有效访问控制，从而实施一种新的安全方法。ABE在诸如智能手机或嵌入式设备等功能完备的计算机系统中实现，并且还可用于增强网络通信的安全性。在基于属性的加密中，加密密钥将与一组属性相关联，这些属性在解密过程中也很有用。使用ABE还可以为众多接收者加密数据，使得只有那些具有正确权限的人才能在以后对其进行解密。由于可以定义广泛的基于密钥的特性，ABE提供了高级别的安全性，并且它足够灵活，可用于各种通信和存储场景。在无线传感器网络（WSN）中，信息通过无线链路从传感器传输到称为汇聚节点的中心位置。WSN中的节点需要执行监视环境的任务，通过传感收集必要的数据，对其进行加密并将其发送到汇聚节点。因此，安全性是无线通信的主要关注点，因为数据是通过恶意入侵者可以访问的开放无线信道传输的。为了解决安全问题，我们提出了一种新的基于属性的加密和基于信任的安全路由算法（ABE-TBSRA）策略，通过将双线性配对和Diffie Hellman加密方案与RSA算法相结合，在发送方本身对数据进行加密和保护。此外，我们提出了一种新的基于信任的安全模型，该模型使用直接、间接和历史信任值三种类型的信任来提高安全性。这种提出的基于加密和信任的安全路由算法的主要优点包括安全级别、数据包交付率、交易可靠性以及网络吞吐量的提高，同时降低了能耗和延迟。
