Apart from this, the scheme in  provides a single keyword search whereas the schemes in [10, 13] handle the conjunctive search queries.
The most recent conjunctive search schemes [30, 33] provide a secure channel-free token transmission.
If T is fresh, the algorithm performs a conjunctive search using (T', C', y).
We highlight the significant characteristics of MUSE-TFV in comparison with the existing multiuser searchable schemes [9, 17-19] and conjunctive search schemes [21-23] in Table 1.
On the other hand, a conjunctive search scheme discussed in  offers such architecture, but it does not support multiple users in the system.
