Wenjun Cui, Mingsheng Hu, Zhijuan Jia, Lipeng Wang · 2019
Based on the intractable problem of discrete logarithm in ECC, this paper presents a new signcryption scheme without using Hash or redundant functions. This scheme has the public verifiability and forward security. Moreover, we analysis its correctness and security. Compared with Zhou scheme, the number of model index is reached the minimum zero time. This makes the scheme have higher security and wider applications.
