A communication terminal is developed based on the Tiny Encryption Algorithm(TEA)and the file tail hiding algorithm.By taking Data Encryption Standard(DES)as the reference and comparison,the TEA is introduced.A file tail hiding based information hiding algorithm integrating information embedding and information extraction is innovatively designed.The visual design is carried out for the algorithm,and an encryption and decryption test is carried out by taking an electronic stamp as an example,so that the hidden communication of the picture is loaded on the communication terminal.The practicability and feasibility of the algorithm are verified.
