“…1, we can clearly understand that our proposed scheme has excellent computational efficiency. Compared with [28], [29] and [32], our scheme has a considerably lower total computation cost than the other three schemes, the total computation cost of our scheme decreased by about 37.29%, 15.18% and 77.79%, respectively. In addition to the excellent computation cost, we can see from Table 3 that our scheme has excellent security and heterogeneity.…”

“…In 2020, By analyzing scheme [26], Qin et al [27] pointed out that the security of traditional searchable encryption schemes could be strengthened and proposed two security concepts: multi-ciphertext indistinguishability (MCI) and MTP. Then, Yang et al [28] designed a searchable encryption scheme meeting MCI and MTP after learning from the articles of Qin et al in 2021.…”

“…According to scheme [28], there are two types of adversaries in CLC environment. A malicious user who can replace the user's public key but does not know the system master secret key is characterized as the first type of adversary, whereas the one that plays KGC and knows the system master secret key plays the second type of adversary.…”

“…For the sake of getting a more intuitive comparison results, we make a quantitative comparison and analysis of the selected schemes. The experimental data were obtained by running MIRACL library on a personal computer equipped with 16GB RAM, Intel processor i5 and Microsoft Windows 10 operating system, and this experimental environment is similar to that of scheme [28]. Table 1 shows the experiment data we obtained.…”

Searchable encryption (SE) technology allows users to use keywords to retrieve encrypted data and ensure that useful plaintext information of encrypted data will not be disclosed. For a secure SE scheme, if it is able to meet the multi-trapdoor privacy (MTP), the security will be improved compare with the traditional SE scheme. However, there are few searchable encryption schemes that can meet the requirement of MTP. In addition, many existing schemes ignore the need of multi keyword search, and both sides of communication use the same cryptosystem and cryptographic parameters, which leads to the problem of low search efficiency and practicability. Therefore, we propose a heterogeneous SE scheme that supports multi-keyword search, provides MTP and allows both sides of communication to be worked in different cryptosystems with different cryptographic parameters. With the use of the random oracle model (ROM), we demonstrate the security of the proposed scheme, and we show the excellent performance of the proposed scheme at the end of the article.
