Abstract

Abstract

The emergence of mobile medical social networks has greatly facilitated the communication of patients' conditions to each other, promoting efficient and high-quality communication and exchange between patients. However, it also causes problems of confidentiality and privacy of patient data. To solve this problem, an attribute-based signcryption scheme based on cloud-assisted verification is proposed, which can effectively protect the privacy of patient data. Patients signcrypt their health information and upload it to the cloud server. When the data user wants to access the patient's information, the cloud server helps the data user partially decrypt and verify the integrity of the data, which reduces the amount of calculation of the data user to a certain extent. At the same time, under the random oracle model, it is proved that the scheme satisfies the unforgeability under the adaptive selection message, the indistinguishability under the adaptive selection ciphertext attack, and the attribute privacy security. Theoretical analysis and numerical simulation experimental results show that the scheme is more efficient than the existing schemes in the signcryption and unsigncryption phases.
