First, an improved self-synchronous chaotic stream cipher algorithm equipped with a sinusoidal modulation, a multiplication, a modulo operation and a round down operation (SCSCA-SMMR) is developed. Using the sinusoidal modulation and multiplication, the improved algorithm can resist the divide-and-conquer attack by traversing multiple nonzero component initial conditions (DCA-TMNCIC). Meanwhile, also by means of the round down operation and modulo operation, on the premise that the DCA-TMNCIC does not work, the original keys cannot be further deciphered only by the known-plaintext attack, the chosen-plaintext attack and the chosen-ciphertext attack, respectively. Then, the Android low-level multimedia support infrastructure MediaCodec class is used to access low-level media encoder\/decoder components and the H.264 hardware encoding\/decoding is performed on real-time videos, so the chaotic video encryption and decryption can be realized in real-time by smartphones. Security analysis and smartphone experimental results verify the effectiveness of the proposed method. <\/jats:p>","DOI":"10.1142\/s0218127421500450","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T08:58:08Z","timestamp":1616403488000},"page":"2150045","source":"Crossref","is-referenced-by-count":6,"title":["Design and Smartphone Implementation of Chaotic Duplex H.264-Codec Video Communications"],"prefix":"10.1142","volume":"31","author":[{"given":"Baoju","family":"Chen","sequence":"first","affiliation":[{"name":"School of Automation, Guangdong University of Technology, Guangzhou 510006, P.
