Definition
Quantum cryptography is an effort to allow two users of a common communication channel to create a body of shared and secret information. This information, which generally takes the form of a random string of bits, can then be used as a conventional secret key for secure communication. It is useful to assume that the communicating parties initially share a small amount of secret information, which is used up and then renewed in the exchange process, but even without this assumption exchanges are possible.

This innovative technology can produce smaller, faster and efficient cryptographic keys using the break through technique of elliptic curve equation rather than employing the traditional method of producing the key as the product of very large prime numbers. Although ECC can be used in collaboration with other public key encryption methods like the RSA, and Diffie-Hellman, it gains upper hand over the other encryption methods in the level of security it offers. A 164-bit ECC key can provide with an equivalent amount of security that a 1024-bit ....etc

As we tend towards a more and more computer centric world, the concept of data security has attained a paramount importance. Though present day security systems offer a good level of protection, they are incapable of providing a trust worthy environment and are vulnerable to unexpected attacks. Palladium is a content protection concept that has spawned from the belief that the pc, as it currently stands, is not architecturally equipped to protect a user forms the pitfalls and challenges that an all-pervasive network such as the Internet poses.

Quantum cryptography becomes a reality
According to reliable sources from NEC, Commercial quantum cryptography, a revolutionary system that can produce quantum keys at a speed of 100Kbit/s and then broadcast it up to 40 kilometres along the commercial fibre optic lines will be available in the markets by the second half of 2005. Speaking in line with Kazuo Nakamura, senior manager of NEC's quantum information technology group at the company's Fundamental and Environmental Research Laboratories, it ca ....etc

IMBRICATE CRYPTOGRAPHY

Security and privacy are critical for electronic communication and e-business. Network security measures are needed to protect data during its transmission. Cryptography plays a vital role in network security as it allows two parties to exchange sensitive information in a secured manner. The word cryptography means covered writingâ„¢. The art or science of transforming an intelligible message into unintelligible one and then retransforming that message back to its origina ....etc
