摘要: A smart city can utilize information and communication technologies to minimize energy, waste, resource consumption attain high-efficiency services, so it directly improves the life quality of all residents. However, also brings about some security privacy challenges. For instance, once ubiquitous network in is attacked, sensitive residents' identities will be revealed. In many application scenarios, anonymity residents a desirable property. After all, nobody wants traced for his daily activity or personal habits. this paper, we propose generic identity-based broadcast encryption scheme which satisfy information's confidentiality users' simultaneously under chosen-ciphertext attacks. What different from our previous work was published ACISP 2016 that present proof focus on environment. The IBBE construction has property its public parameter size private key are constant as well decryption cost independent number receivers. Thus, no matter point views, very appropriate system.
