What is the definition of stream cipher? A. Cryptography wherein two keys are used: one to encrypt the message and another to decrypt it B. A cryptographic method in which someone chooses a number by which to shift each letter of a text in the alphabet and substitute the new letter for the letter being encrypted C. A form of cryptography that encrypts the data as a stream, one bit at a time D. A method other than brute force to derive a cryptographic key

C. A form of cryptography that encrypts the data as a stream, one bit at a time

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.

Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

A stream cipher is a form of cryptography that is typically designed to encrypt a stream of data, one bit at a time. Thus, each bit corresponds to series of information within a data stream and they are encrypted one after the other.
