The S-box maps an 8-bit input, c, to an 8-bit output, s = S(c). Both the input and output are interpreted as polynomials over GF (2). First, the input is mapped to its multiplicative inverse in GF (28) = GF (2) [x]/ (x8 + x4 + x3 + x + 1), Rijndael's finite field. Zero, as the identity, is mapped to itself.

Several 8-bit character sets (encodings) were designed for binary representation of common Western European languages ( Italian, Spanish, Portuguese, French, German, Dutch, English, Danish, Swedish, Norwegian, and Icelandic ), which use the Latin alphabet, a few additional letters and ones with precomposed diacritics, some ...
The E series is a system of preferred numbers (also called preferred values) derived for use in electronic components. It consists of the E3, E6, E12, E24, E48, E96 and E192 series, [1] where the number after the 'E' designates the quantity of logarithmic value "steps" per decade.
Hypertext Transfer Protocol Secure ( HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It uses encryption for secure communication over a computer network, and is widely used on the Internet. [1] [2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets ...
USB-C, or USB Type-C, is a 24-pin connector (not a protocol) that supersedes previous USB connectors and can carry audio, video and other data, e.g., to drive multiple displays or to store a backup to an external drive. It can also provide and receive power, such as powering a laptop or a mobile phone.
