Parallel Optimized Attribute-Based Encryption Scheme Based on SM9
Xuguang Wu · 2022
With the development of cloud computing, secure file storage based on it is even more widely popular. Attribute-based encryption (ABE) is one of the key cryptographic techniques to solve the security of cloud storage. China has independently developed its own cryptography industry standard - SM9 identification encryption, which will be wildly used in many areas. However, the current SM9-based ABE scheme cannot effectively utilize the parallelized resources of cloud computing. With the parallel computing technology, a parallel optimized ABE scheme based on SM9 is proposed. The scheme's accuracy and security are carefully examined, and its effectiveness is examined through tests.
