IND-CCA secure symmetric encryption
In Authenticated Encryption, the authors explained the framework and constructions for Authentication Encryption in detail.
In particular, In Theorem 3.2 they stated that &quot;INT-CTXT&quot; security together with &quot;IND-CPA&quot; security implies &quot;IND-CCA&quot; security.
Then, they introduced a general approach to an &quot;Encrypt-then-MAC&quot; construction that achieves both &quot;INT-CTXT&quot; and &quot;IND-CPA&quot; security, which further implies &quot;IND-CCA&quot; security.
