It has been applied in cloud computing, TV broadcasts, and many other scenarios. Inner product broadcast encryption takes merits of both broadcast encryption and inner product encryption. However, it is crucial to reduce the computation cost and to take the recipient\u2019s privacy into consideration in the inner product broadcast encryption scheme. In order to address these problems, we focus on constructing a secure and practical inner product broadcast encryption scheme in this paper. First, we build an anonymous certificate-based inner product broadcast encryption scheme. Especially, we give the concrete construction and security analysis. Second, compared with the existing inner product broadcast encryption schemes, the proposed scheme has an advantage of anonymity. Security proofs show that the proposed scheme achieves confidentiality and anonymity against adaptive chosen-ciphertext attacks. Finally, we implement the proposed anonymous inner product broadcast encryption scheme and evaluate its performance. Test results show that the proposed scheme supports faster decryption operations and has higher efficiency.<\/jats:p>","DOI":"10.1155\/2021\/6639835","type":"journal-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T15:20:23Z","timestamp":1630423223000},"page":"1-17","source":"Crossref","is-referenced-by-count":2,"title":["Anonymous Certificate-Based Inner Product Broadcast Encryption"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1181-1258","authenticated-orcid":true,"given":"Shuang","family":"Yao","sequence":"first","affiliation":[{"name":"Department of Computer and Information Technology, Beijing Jiaotong University, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Security and Privacy in Intelligent Transportation, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5942-8245","authenticated-orcid":true,"given":"Dawei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Technology, Beijing Jiaotong University, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Security and Privacy in Intelligent Transportation, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","first-page":"480","article-title":"Broadcast encryption","author":"A.
