SMEmail is a cryptographic protocol for securing e-mail in mobile environments. It is a secure application layer protocol that provides several security attributes such as confidentiality, integrity, authentication, non-repudiation, and forward secrecy of message confidentiality for the electronic mails. SMEmail provides an elliptic curve-based public key solution that uses public keys for the secure key establishment of a symmetric encryption. It combines encryption and digital signature, and uses public keys for a secure key establishment where the established session key is used for enciphering contents via a symmetric encryption. It also deploys elliptic curves and the concept of signcryption while it encrypts data using a symmetric enciphering algorithm.
