Deniable Encryption based on Standard RSA with OAEP

There are various methods of anti-forensics many of which are simple and robust, however, some advanced techniques such as Deniable Encryption not only are powerful but also proven to be unbreakable in the mathematical sense. Thus, studying them has a crucial role in the science of digital forensics research. In this research, we propose a new technique for deniable encryption based on RSA with OAEP. The technique is motivated by a work of Klonowski et al. and has security property of sender-deniability without any required pre-shared keys. Moreover, since the proposed method is based on widely-used RSA encryption the deniable encryption raises much less suspicion. Thereafter, by presenting implementation results, we show the applicability of our scheme.
