Most cryptographic mechanisms such as symmetric and asymmetric cryptography, often involve the use of cryptographic keys. However, all cryptographic techniques will be ineffective if the key distribution mechanism is weak. Quantum Key Distribution or Quantum Cryptography is attracting much attention as a solution of the problem of Key Distribution; QKD offers unconditionally secure communicatio...

Most of the security architecture uses public key cryptosystems for authentication and to secure the communication that takes place on distributes sites. Now a day’s identity based cryptography and certificate-less public key cryptography are used for enhancing the security. Certificate-less based cryptography has reduced the certificate necessity for key distribution and reducing the problem o...

This is a survey on application of Identity-Based Cryptography in mobile ad hoc networks. In this survey, we review all papers that are available in the literature on security schemes on mobile ad hoc networks using Identity-Based Cryptography during years 2001 to 2007. To introduce the topic, we first review most important developments on general Identity-Based Cryptography. The survey introdu...

Quantum cryptography is a promising solution towards absolute security in long term cryptosystems. While the use of quantum cryptography in fiber optical networks gets significant advances, research on the application of quantum cryptography in mobile wireless network is still premature. In this paper, we analyze the interests of using quantum cryptography in 802.11 wireless networks, and propo...

1. Introduction Quantum cryptography is a technology that ensures ultimate security 1). Compared to current cryptography that could be defeated by the development of an ultra high-speed computer, quantum cryptography ensures secure communication because it is based on the fundamental physical laws. Among the various quantum information technologies, the most extensive research is being conducte...
