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. I turn now to the specific field covered by this debate in the field of cryptography.

From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Cryptography, that is, the electronic coding of data, has advantages in terms of confidentiality, but it also offers a refuge for organized crime. From Europarl Parallel Corpus - English A key tool to secure the confidentiality of electronic communications is encryption or cryptography. From Europarl Parallel Corpus - English In other words cryptography can be used as an electronic signature. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Cryptography is a crucial point in the debate on protecting citizens and businesses. From Europarl Parallel Corpus - English I am not sure that the section on approved cryptography providers could not have been dropped altogether.
