增强量子密码数据安全性的机制研究进展

Development of mechanism for enhancing data security in quantum cryptography

Ajit Singh, Nidhi Sharma

摘要:

在网络通信中,通信的安全性越来越重要,因为许多类别的数据都需要对访问、修改、删除和插入的授权进行限制。量子密码是利用偏振特性来保证传输数据不被篡改的解决方案之一。研究论文提供了增强量子密码在信息交换过程中的数据安全性的机制。在第一阶段中,详细解释了量子密钥分配的BB84协议。该机制以BB84协议为基础。在下一阶段中,解释所提出的机制。该机制将BB84协议从发送者到接收者再从接收者到发送者两个层次结合起来。此外,使用逻辑电路来组合比特,从而降低窃听的可能性。所获得的密钥可以用于安全地交换信息,还可以帮助加密和解密关键数据。双层BB84机制将有助于信息协调以及隐私放大。在将来,所提出的机制将是非常有益的无条件的安全性,需要在关键和其他秘密信息交换

英文摘要:

Nowadays security in communication is increasingly important to the network communication because many categories of data are required restriction on authorization of access, modify, delete and insert. Quantum cryptography is one of the solutions that use property of polarization to ensure that transmitted data is not tampered. The research paper provides the mechanism that enhances the data security in quantum cryptography during exchange of information. In first phase detailed explanation of Quantum key distribution's BB84 protocol is given. BB84 protocol is used as the basis for the mechanism. In next phase the proposed mechanism is explained. The proposed mechanism combines BB84 protocol at two levels, from sender to receiver and then from receiver to sender. Moreover, a logic circuit is used to combine the bits hence to reduce the probability of eavesdropping. The key obtained can be used to exchange the information securely further it can help in encryption and decryption of crucial data. Double level BB84 mechanism will help in information reconciliation as well as privacy amplification. In future the proposed mechanism will be very beneficial where unconditional security is required during key and other secret information exchange
