Since 1997, 10 papers have been published in IEEE Transactions on Information Theory. The main academic achievements include: Haenszel lifting of some binary BCH codes over Z_4- rings completed by 1998 can't increase the minimum distance. In the form of preprint, it was developed by R. Calder Bank (IEEE Fellow, former vice president of information science research? At&T Company. T Lab, a professor of electrical engineering, mathematics and applied and computational mathematics at Princeton University, introduced the historical summary of coding theory he wrote for the 50th anniversary of information theory: The Art of Signal: Fifty Years of Coding Theory (see the special issue of IEEE Transactions on Information Theory 1998 10 to commemorate the 50th anniversary of information theory); His other work (cooperation with Stephen S.-T.Yau) was introduced into the historical review of algebraic geometric codes at the same time.

In recent years, algebraic geometry method has been introduced into the study of quantum entanglement, which is an important branch of quantum information theory. His work on Hamilton sub-simulation in two-particle quantum system was called "an important achievement" by C.H.Bennett, one of the founders of quantum information theory, and was reviewed by Chen Hao and Ashikhmin-Litsyn-TSF Asman, one of the reviewers of Quantum Information and Computing (Ashikhmin is an IEEE Transactions on? The current deputy editor-in-chief of information theory, Litsyn is the former deputy editor-in-chief of IEEE Transactions on Information Theory, TSAF· assmann is one of the founders of algebraic geometric code theory, and the best paper of IEEE Information Theory Society? Award winner) constructed the first asymptotically good quantum error-correcting code sequence by algebraic geometry method almost simultaneously and independently.

In recent years, in cooperation with Cramer of CWI in the Netherlands and Goldwasser of MIT, the application of algebraic geometric codes and random error correction codes in secure multiparty computing has greatly improved the communication efficiency of the protocol. The paper was published in Crypto 2006, EuroCrypt 2007, EuroCrypt 2008 and Crypto 2009, and it is one of the few series of works published by China scholars at secret meetings in the United States. In recent years, Chen Hao's research achievements in the field of wireless security were published in ACM WiSec20 10, the most important academic conference in the field of wireless network security.
