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 ).
Unlike a modern stream cipher (such as those in eSTREAM), RC4 does not take a separate nonce alongside the key. This means that if a single long-term key is to be used to securely encrypt multiple streams, the protocol must specify how to combine the nonce and the long-term key to generate the stream key for RC4.
It's unclear exactly how O'Leary might change TikTok's algorithms; however, similar short-form video services exist elsewhere on social media with their own proprietary algorithms, and he said a ...

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.
