摘要：Wireless network is one of most important modes of communication. So providing security to theinformation being communicated through wireless networks is very important issue. Classical cryptography providesconditional security which has many loop holes whereas quantum cryptography promises to be unconditionally securefor wireless networks, recently implementation of quantum cryptography in wireless communication systems using aquantum key distribution (QKD) protocol is done. Cryptography is the technique for secure communication of data inthe presence of third parties, called adversary. Quantum cryptography relies on two important elements of quantummechanics-The Heisenberg uncertainty principle and the principle of photon polarization.The main weakness ofclassical cryptography is that it does not provide any method to sender and receiver to find out the presence ofadversary. Quantum cryptography deals with almost all loopholes found in classical cryptosystem. It providesunconditional security by encrypting the message using standard one time pad encryption scheme. The use of quantumcryptography in optical fibre cables has significant advantages.
