Stream ciphers work better than block ciphers for many communication systems such as wireless communications (wifi).

a. True

b. False

The statement that stream ciphers work better than block ciphers for many communication systems such as wireless communications (wifi) is true.

This ciphers combine the the plain-text bits or bytes with a pseudo-random bit stream.

stream chipghers are sutable for network communications. Example: the RC4 cipher and the A5 algorithmare used in cellular-based Global System for Mobile (GSM) communications
