Problems solved by technology

[0010] (3) Computational overhead: Existing multi-receiver signcryption schemes are based on bilinear pairings. There are few subgroups that meet the requirements, and the computational overhead is huge, so they are not suitable for computing-limited terminal systems.
In the literature, bilinear pairing is used to generate data encapsulation keys, and the computational complexity and resource consumption are relatively large
Use the Lagrange interpolation polynomial to hide the identity information of the recipient, but it is proved that this method has a huge loophole, and the identity information of th

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] The smart metering system of the smart grid includes a layered network of servers, concentrators, a large number of smart meters and household electrical equipment, and is a system with limited communication bandwidth and computing power. Servers in traditional networks need to generate and manage a large number of keys, which undoubtedly makes the server a heavy burden. A large number of groups and end-to-end reliable communication is also required between the server and the smart meter.

Abstract

The invention discloses a multi-receiver hybrid signcryption algorithm without bilinear pairings. The multi-receiver hybrid signcryption algorithm includes the five processes of secret key generation center initialization, extraction of a part of private keys, secret key extraction, signcryption and unsigncryption. Two-way communication signcryption of multiple receivers is achieved, the signcryption algorithm in the scheme is achieved without the bilinear pairings, calculation expenses are greatly reduced, and universality is better; compared with traditional schemes, counterfeit attacks of a positive and dishonest secret key generation center can be defended, and safety is higher.

Description

technical field [0001] The invention relates to a multi-receiver hybrid signcryption scheme without bilinear pairing, which mainly combines the non-certificate public key encryption technology without bilinear pairing with hybrid signcryption to realize multi-party communication, and belongs to the technical field of telecommunications. Background technique [0002] The rapid development of computer and network technology has led to the popularization of digital services. The key distribution and update technology related to the secure multicast service of the network service system has become a research hotspot in the field of information security. [0003] Traditional public key algorithms need to use the multicast key and the public key of each receiving terminal to encrypt and send the same message one by one when sending the same message. The amount of distributed data is large and the process takes a long time, which greatly reduces system performance. [0004] Signcr...
