The most obvious and common application of cryptography is for securing communications, thus ensuring confidentiality and privacy. The implementation of a publickey cryptography package needs to ensure that the random number object used in the generation of key pairs cannot be accessed by clients of the package. Components for these systems are now commercially available, and it seems very likely that quantum cryptography will be an important technology long before quantum computers of useful size are constructed. The sections on quantum cryptography, quantum proper ties of squeezed light, and experimental effor ts to measure gravitational waves provide adequate introduction to these exciting applications of quantum optics. In contrast to symmetric cryptosystems, public key cryptography is a form of cryptography which generally allows users to communicate securely without having prior access to a shared secret key. Recall that, in case of asymmetric cryptography, the decryption key for a ciphertext is the inverse of the key that was used to create the ciphertext.

Issues regarding security, and how some of these can be addressed through the use of cryptography, are described. The most efficient way to solve this problem is cryptography. The algorithm is used in public key cryptography which was described in previous question. Traditionally and for thousands of years people have used what is known as private-key cryptography. Cryptography is the art of sending secret messages. They developed an idea known as public-key cryptography. Language features which have been studied using -like techniques include cryptography, object-oriented languages, distribution, concurrent higher-order languages, pointers, heap regions and exceptions. Modern-day cryptography is considered the science of information security. The issue of security is considered next as well as how cryptography can be used to enhance security and trust in agent-mediated e-commerce. Most current cryptography, included in electronic commerce, is based on the fact that no sufficiently fast factorisation method is known to classical computers. When designing the system using public-key cryptography we must make sure, that computing the private-key from the public-key is infeasible. Cryptography is strictly associated with encryption and decryption. In the modern world this is closely linked with computers, however cryptography existed many years before the traditional computer. No matter how powerful a computer is however, some cryptography techniques are unbreakable, for example the one-time pad technique. These examples are from corpora and from sources on the web.
