摘　　要：在21世纪人类跨入信息时代之际,如何能够实现保密通信的不可破译性是现代通信技术面临的重要问题,也是哲学工作者需要思考的重要问题。量子密码术在保证信息的不可破译性方面已经取得重要进展。通过对非量子密码术和量子密码术两个阶段分别以科学的和哲学的解析,文章认为,古代密码术具有弱不可破译性,发展到经典密码术阶段,密码术在理论和实践上呈现强不可破译性,而量子密码术则显示出不可破译性,逐渐趋向"绝对不可破译性"。At the time when man enter the Information Age in the twenty -first century, how could we guarantee that the communications systems can＇ t be decrypted？ In this respect, quantum cryptography has made great progress. By analyzing the development of cryptography both scientifically and philosophically from the non -quantum cryptography phase to the quantum cryptography phase, we conclude that the ancient cryptography is of weak uneraekability, and when it developed into the stage of the classical cryptography its theory and practice take on the strong- uncrackability, while the quantum cryptography tends to be uncrakable, and it is gradually becoming imperatively uncrakable.

关 键 词：密码术 量子密码 不可破译性
