Which of the following ciphers would be BEST used to encrypt streaming video?

The correct answer is B. RC4. RC4 (B) is a stream cipher that encrypts data one bit or byte at a time, making it well-suited for continuous streaming data such as video. Stream ciphers have low latency and minimal computational overhead. RSA is an asymmetric algorithm used for key exchange, not bulk…

Explanation

RC4 (B) is a stream cipher that encrypts data one bit or byte at a time, making it well-suited for continuous streaming data such as video. Stream ciphers have low latency and minimal computational overhead. RSA is an asymmetric algorithm used for key exchange, not bulk encryption. SHA1 is a hashing algorithm, not an encryption cipher at all. 3DES is a block cipher - it processes fixed-size chunks of data, introducing overhead and latency that make it poorly suited for real-time streaming workloads.
