A heterogeneous signcryption scheme for smart grid with trusted multi-ciphertext equality test by Xiaodong Yang, Ruixia Liu, Bin Shu, Ningning Ren, Wenjia Wang

“…Under the random oracle model, on the basis of the bilinear Diffie-Hellman, the computational Diffie-Hellman and the q-strong Diffie-Hellman problems, this paper proves that the scheme proposed herein meets the requirements of indistinguishability and one-way security under adaptive choice ciphertext attacks, and the unforgeability under the adaptive choice message attack. …”
