I would say it has to be b but its what the correct answer is its up to you!
I hoped this helped you out!
Have a nice day!
Answer:
The correct answer is letter "A": The message is broken into independent blocks which are encrypted.
Explanation:
There are five (5) main forms of encryption: <em>Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Output Feedback (OFB)</em>. Electronic Code Book (ECB) is the simplest of all of them. Using this method to encrypt information implies dividing a message into two parts to encrypt each block independently. ECB does not hide patterns effectively because the blocks are encrypted using identical plaintexts.
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
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. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
