Internet of things environment is adopted widely in different industries and business organizations with varying capacity. It provides a favorable environment to outsource the crowdsourced data in the cloud to minimize the cost of computation, which is called crowdsourcing. Crowdsourcing is a technique where individuals or organizations obtain goods and services. A professional or industry outsource the crowdsourced data in the cloud, where confidentiality and authenticity of data become essential. Signcryption is the cryptographic technique that serves both the authenticity and the privacy of transmitted messages. This technique ensures secure authentic data transmission and storage. Therefore, this paper proposes an identity-based signcryption scheme. In the proposed PSSCC framework, the user does pairing free computation during signcryption, which makes efficient calculation on user-side. Moreover, PSSCC framework is proved secure under modified bilinear Diffie-Hellman inversion and modified bilinear strong Diffie-Hellman problems. The performance analysis of PSSCC with related schemes indicates that the proposed system supports efficient communication along with less computation cost.

PSSCC：用于众包工业物联网环境的可证明安全的通信框架

物联网环境在不同行业和不同容量的商业组织中被广泛采用。它提供了一个有利的环境，将云中的众包数据外包，以最大限度地降低计算成本，这被称为众包。众包是个人或组织获得商品和服务的一种技术。专业人士或行业外包云中的众包数据，其中数据的机密性和真实性变得至关重要。签密是一种加密技术，它既能保证传输消息的真实性，又能保证消息的私密性。该技术确保安全可靠的数据传输和存储。因此，本文提出了一种基于身份的签密方案。在提议的 PSSCC 框架中，用户在签密期间进行免费配对计算，在用户端进行高效计算。此外，PSSCC 框架在改进的双线性 Diffie-Hellman 反演和改进的双线性强 Diffie-Hellman 问题下被证明是安全的。PSSCC 与相关方案的性能分析表明，所提出的系统支持高效的通信以及较少的计算成本。
