在全球范围内,“双碳”目标成为应对气候变化和推动经济可持续发展的当务之急。物流业是经济活动的重要组成部分,其绿色转型成为实现“双碳”目标的关键举措。在此过程中,物流业的高质量发展与环境友好型经济的构建密不可分,其在推动流通业可持续发展、减缓气候变化等方面发挥着积极作用。“双碳”目标,即碳达峰和碳中和,旨在使单位国内生产总值碳排放在特定年份达到峰值后逐步减少,最终实现碳中和状态。在此背景下,物流业的绿色转型成为实现低碳经济、建设生态文明的迫切需求。文章聚焦于物流业的绿色转型对流通业高质量发展的影响,深入分析其在经济结构调整、能源利用优化等方面的作用,旨在为实现“双碳”目标下的可持续发展提供科学依据。

With the popularity of cloud computing and mobile Apps, on-demand services such as on-line music or audio streaming and vehicle booking are widely available nowadays. In order to allow efficient delivery and management of the services, for large-scale on-demand systems, there is usually a hierarchy where the service provider can delegate its service to a top-tier （e.g., countrywide） proxy who can then further delegate the service to lower level （e.g., region-wide） proxies. Secure （re-）delegation and revocation are among the most crucial factors for such systems. In this paper, we investigate the practical solutions for achieving re-delegation and revocation utilizing proxy signature. Although proxy signature has been extensively studied in the literature, no previous solution can achieve both properties. To fill the gap, we introduce the notion of revocable and re-delegable proxy signature that supports efficient revocation and allows a proxy signer to re-delegate its signing right to other proxy signers without the interaction with the original signer. We define the formal security models for this new primitive and present an efficient scheme that can achieve all the security properties. We also present a secure on-line revocable and re-delegate vehicle ordering system （RRVOS） as one of the applications of our proposed scheme.

Digital signature is one of the most important cryptography primitives. Recently, more and more works have been done to construct signatures over lattice problems to keep them secure in the quantum age. Among them, a ring-based signature scheme named Dilithium is the most efficient one and a candidate in the third round of the National Institute of Standards and Technology’s post-quantum cryptography project. To make those schemes work well in large network, we constructed the first ring-based Identity-based signature(IBS) scheme for light-weight authentication. The construction in this paper relies on the transformations introduced by Bellare et al. in Journal of Cryptology(Vol.22, No.1, pp.1–61, 2009)and its security can be proved under the hardness of ringlearning with errors problem in the random oracle *** to better trapdoor and polynomial ring setting,our proposed scheme are much better than the previous ones in terms of both computation and communication complexities.

Functional signatures(FS) enable a master authority to delegate its signing privilege to an assistant. Concretely, the master authority uses its secret key skFto issue a signing key skffor a designated function f ∈ FFSand sends both f and skfto the assistant E, which is then able to compute a signature σf with respect to pkFfor a message y in the range of f. In this paper, we modify the syntax of FS slightly to support the application scenario where a certificate of authorization is necessary. Compared with the original FS, our definition requires that FFSis an injective function family and for any f0, f1 ∈ FFS there does not exist an intersection between range(f0) and range(f1). Accordingly, we redefine the security of FS and introduce two additional security notions, called unlinkability and accountability. Signatures σfin our definition do not expose the intention of the master authority. We propose two constructions of FS. The first one is a generic construction based on signatures with perfectly re-randomizable keys, non-interactive zero-knowledge proof(NIZK) and traditional digital signatures, and the other is based on RSA(RivestShamir-Adleman) signatures with full domain hash and NIZK. We prove that both schemes are secure under the given security models.
