چكيده فارسي :
With the rapid growth of information and popularity of
outsourced data, most of the IT companies are motivated to
outsource their sensitive information on cloud servers. Since these
servers are not fully trusted, for preserving privacy and security,
these data must be encrypted before being outsourced. For
searching on the encrypted data, searchable encryption method
plays an important role. Recently, Tajiki et al. have proposed a
new asymmetric searchable encryption called Secure Searchable
Asymmetric Encryption (SSAE). They claimed their scheme is
secure against forgery attack. In this paper, at first, we show that
the security of SSAE is not complete by presenting a forgery attack
on this scheme. After that we modify the SSAE to withstand this
forgery attack.
