Shannon rate distortion theory
WebbRate distortion theory is considered for the Shannon cipher system (SCS). The admissible region of cryptogram rate R, key rate R/sub k/, legitimate receiver's distortion D, and wiretapper's uncertainty h is determined for the SCS with a noisy channel. WebbInformation theory is the mathematical study of the quantification, storage, and communication of information. [1] The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s.

Webbdistortion–free), and the second, which is related, is that the encryption and the decryption units share identical copies of the same key. Yamamoto [11] has relaxed the first assump-tion and extended the theory of Shannon secrecy systems into a rate–distortion scenario, allowing lossy reconstruction at the legtimate receiver. 1. CCIT ... Rate–distortion theory was created by Claude Shannon in his foundational work on information theory. In rate–distortion theory, the rate is usually understood as the number of bits per data sample to be stored or transmitted. The notion of distortion is a subject of on-going discussion. Visa mer Rate–distortion theory is a major branch of information theory which provides the theoretical foundations for lossy data compression; it addresses the problem of determining the minimal number of bits per symbol, as … Visa mer Distortion functions measure the cost of representing a symbol $${\displaystyle x}$$ by an approximated symbol $${\displaystyle {\hat {x}}}$$.
