杨义先

Yang Yixian is a prolific Chinese author in popular science and cybersecurity writing; publicly available information about him is limited, and no systematic account of his life or education has been disclosed. Eight of his works are carried in the library, spanning communications technology, cryptography and security, artificial intelligence, and biographies of scientists, reflecting a writing approach that combines technical depth with humanistic concern. He is skilled at unpacking specialized topics through historical narrative and accessible language: A Brief History of Cryptography and A Brief History of Security place concepts such as privacy protection and quantum cryptography within a long historical arc, while The Story of Communications traces the development of communications in a relaxed tone. Hacker Psychology and Thirty-Six Stratagems of Cybersecurity focus on social engineering and everyday protection for general readers. Biographies of Scientists and A Brief History of the Future of AI further extend his scope to personal stories and imaginative frontiers such as brain-computer interfaces. His style balances informative content with readability, making it well suited to introductory popular-science reading.
