A secure electronic messaging system (SEMS) provides absolute system security and user-defined message security for electronic messaging between two public entities. These messages can be of any kind provided the contents are created using a defined master alphabet of 81 characters of less. The SEMS encrypts and decrypts source message data using a series of message keys that are derived from a private, numeric orginal key known only by both parties sending and receiving messages. The message key suite absolutely secures the original key from discovery. The secure distribution of these original keys will be under the same methods that the public entities would use to discover each other such as opening an acount, making a public inquiry for membership, etc. The system is based on the simple mathematics for secure electronic monetary transactions that translates source numbers into encrypted cipher numbers. The SEMS translates message content characters into numbers based on a message key suite dependent distribution of the master alphabet and then uses a series of equations to encrypt the numbers. The formulas return every possible number value, except the input value, and are completely dependent on the message key suite. Because there are no hidden parts, the architecture of the SEMS is completely available to anyone in the public sector. This openness makes attempting message decryption worthless. The only way to break an individual message is to attempt all user-defined message key possibilities, and even if successful, the original key can not be derived or discovered. The only way to get the key is to physically steal it; which is the constant risk entailed in secure messaging. The total openness and absolute security delivered by the SEMS is what is missing in all other available secure messaging schemes, and it is what is required by the public to have complete confidence in electronic messaging and commerce. |
