Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Confidentiality and authentication are two main security goals in secure electronic mail (e-mail). Pretty good privacy (PGP) and secure/multipurpose internet mail extensions (S/MIME) are two famous secure e-mail solutions. Both PGP and S/MIME use digital envelope to provide message confidentiality and digital signature to provide message authentication. Hover, these methods have the following two aknesses: 1) digital signature provides non-repudiation evidence of sender that is not desired in some e-mail applications and 2) efficiency is low, since these methods use two kinds of public key cryptographic primitives: public key encryption and digital signature. To overcome the above two aknesses,  introduce a new concept called deniably authenticated encryption that can achieve confidentiality, integrity, and deniable authentication in a logical single step.  first propose a deniably authenticated encryption scheme and prove its security in the random oracle model. Then,  design a secure e-mail protocol using the proposed deniably authenticated encryption scheme. The deniable authentication property protects senders’ privacy.
