Abstract: In today’s digital age, data centers have become one of the most important infrastructures in businesses and organizations. They store and manage critical enterprise data and resources, as well as being the core support for business operations. However, as data centers grow and expand, cybersecurity has become an important challenge. In order to efficiently retrieve ciphertexts and achieve secure communication between data center and data user, this article proposes a multi-ciphertext equality test broadcast signcryption scheme. The scheme uses broadcast signcryption technology to ensure the confidentiality and unforgeability of messages, and uses multi-ciphertext equality test to achieve efficient retrieval of ciphertexts on cloud servers. Based on the hypothesis of difficult problems, the security of the scheme has been proven under the random oracle model. Numerical analysis shows that our work has relatively high computational and communication efficiency, when the number of receivers is 100, the computational efficiency of our scheme has increased by more than 20% compared to the existing schemes and is suitable for data communication in data center.
