Stream cipher. The operation of the keystream generator in A5/1, an LFSR-based stream cipher used to encrypt mobile phone conversations. A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the ...
Keystream. In cryptography, a keystream is a stream of random or pseudorandom characters that are combined with a plaintext message to produce an encrypted message (the ciphertext). The "characters" in the keystream can be bits, bytes, numbers or actual characters like A-Z depending on the usage case. Usually each character in the keystream is ...
Character generator. An Aston Ethos hardware character generator. A character generator, often abbreviated as CG, is a device or software that produces static or animated text (such as news crawls and credits rolls) for keying into a video stream. Modern character generators are computer-based, and they can generate graphics as well as text.
Livestreaming, live-streaming, or live streaming is the streaming of video or audio in real time or near real time. It is often referred to simply as streaming, though recorded content, such as video-on-demand, vlogs, and YouTube videos, are streamed as well but not live . Livestreaming services encompass a wide variety of topics, from social ...
Live streaming. In August 2015, Facebook began to allow users to live stream video. Streams appear on the News Feed, and users can comment on them in real-time. Live broadcasts are automatically saved as a video post to the streamer's page. The feature was positioned as a competitor to services such as Meerkat and Periscope.
A cryptographically secure pseudorandom number generator (CSPRNG) or cryptographic pseudorandom number generator (CPRNG) [1] is a pseudorandom number generator (PRNG) with properties that make it suitable for use in cryptography. It is also loosely known as a cryptographic random number generator (CRNG), [2] [3] which can be compared to "true ...
Livestreaming, live-streaming, or live streaming is the streaming of video or audio in real time or near real time. While often referred to simply as streaming, the real time nature of livestreaming differentiates it from other forms of streamed media, such as video-on-demand, vlogs, and YouTube videos. Livestreaming services encompass a wide ...
