基于中国剩余定理的数据广播加密方案

An Encryption Technique Based on the Chinese Remainder Theorem for Secure Data Broadcasting

数据广播技术在各个领域得到广泛应用.公钥制密码学也被引入数据广播中以实现数据的秘密广播.目前广泛使用的多重密钥方案和门限方案有其局限性,需要一种具有更高效率和适用性的数据广播加密方案.基于中国剩余定理的改进方案具备了简洁的实现模型和理想的抗攻击性,具有更为实际的应用价值.

With the development of network technology, Data Broadcasting has been introduced into many areas for the sake of its simplicity and economy in communication. Public-key Cryptography is applied to insure security and therefore secure broadcasting achieved. In this paper, an encryption techniques based on the Chinese Remainder Theorem for secure broadcasting is proposed and some of its properties including algorithms, real models, cipher protocol and anti-attack capacity are discussed.
