Quark CopyDesk is primarily used by newspapers and magazines to write, edit and style text (copy). The software includes standard word processing features such as spell check, track changes and word count. Its integration with QuarkXPress allows exact copy fitting information and previews, which ensures the editor to see whether the text fits ...
The Protection of Information in Computer Systems is a 1975 seminal publication by Jerome Saltzer and Michael Schroeder about information security. [ 1 ] [ 2 ] The paper emphasized that the primary concern of security measures should be the information on computers and not the computers itself.
The security of their system is based on the Phi-hiding assumption. In 2004, Helger Lipmaa [ 5 ] achieved log-squared communication complexity O ( ℓ log n + k log 2 n ) {\displaystyle O(\ell \log n+k\log ^{2}n)} , where ℓ {\displaystyle \ell } is the length of the strings and k {\displaystyle k} is the security parameter.
The following outline is provided as an overview of and topical guide to computer security: . Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the ...
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. [1] [2] The best known example of quantum cryptography is quantum key distribution, which offers an information-theoretically secure solution to the key exchange problem.
The Computer Security Act of 1987, Public Law No. 100-235 (H.R. 145), (Jan. 8, 1988), is a United States federal law enacted in 1987. It is intended to improve the security and privacy of sensitive information in federal computer systems and to establish minimally acceptable security practices for such systems.

That these codes allow indeed for quantum computations of arbitrary length is the content of the quantum threshold theorem, found by Michael Ben-Or and Dorit Aharonov, which asserts that you can correct for all errors if you concatenate quantum codes such as the CSS codes—i.e. re-encode each logical qubit by the same code again, and so on, on ...
