Mobile phone encrypted short message structure and method for transmitting and receiving mobile phone encrypted short message by applying same

Abstract

The invention refers to a mobile phone encrypted short message structure and a method for transmitting and receiving a mobile phone encrypted short message by applying the structure. The method for transmitting and receiving the mobile phone encrypted short message comprises the steps of: a) enabling a sending terminal user to send an encrypted short message, which comprises the following steps of: S11) editing short message content; S12) obtaining an abstract value of the short message content; S13) applying a signature to the abstract value by utilizing a DSA (digital signature algorithm) encryption private key of the sending terminal user; S14) performing encryption on the signature and the short message content by utilizing a RSA (Rivest-Shamir-Adleman) encryption public key in a digit certificate of a receiving terminal user; and S15) sending the encrypted short message, wherein the encrypted short message structure is the special structure of the invention; and b) enabling the receiving terminal user to receive and read the encrypted short message, which comprises the following steps of: S21) enabling the receiving terminal user to receive the encrypted short message; S22) decrypting the encrypted short message by utilizing a RSA encryption private key of the receiving terminal user; and s24) reading the encrypted short message content.
