Disclosed are an encryption method and system. The method comprises the steps of providing a message to be encrypted, said message having a string of characters; and providing a matrix having characters in a last row and numbers in all other rows. A string of numbers is formed from said string of characters by selecting the number in the next to last row in said matrix in the column corresponding to a character of said string of characters. The remaining numbers in said column are shifted down one row, and the selected number is placed in a queue. The method comprises the further steps of continuing until upon depletion of numbers from a column, shifting columns in said matrix, refilling the empty column with numbers from said queue, and shifting each row in said matrix.

Matrix encryption method and system

A messaging system and method suitable for use with wireless mobile terminals. The system includes a message server for receiving and sending messages and converting messages to a baseline such as an XML representation; a message processor for controlling the system's operation; a database for storing information about messaging capabilities of mobile terminals; and a transcoder for filtering the baseline representation according to the capability of a mobile terminal. A subscriber enters a profile that includes the messaging capability of the mobile terminal, which is stored in the database. When the server receives a message for the subscriber's terminal, it converts the message to the baseline. The transcoder filters the baseline according to the capability of the terminal, and returns the result to the server for format and protocol conversion and sending to the terminal.
