Encryption

Question 1

CBC

Answer 1

CBC (Cipher Block Chaining)

An encryption mode where each data block is combined with the previous encrypted block, refers to a block cipher mode that works by chaining the cipher-text blocks together, such that each cipher-text block depends on the previous block, This makes it much more secure than ECB, as patterns in data are concealed.

Question 2

CFB

Answer 2

CFB (Cipher Feedback)

An encryption mode that converts block ciphers into stream ciphers by processing data in smaller chunks enabling the encryption of individual bits or bytes of data. It’s often used when flexibility and real-time encryption are needed.

Question 3

ECC

Answer 3

ECC (Elliptic Curve Cryptography)

Uses complex mathematical curves for encryption. cryptographic solution would be best suited for low-power devices, such as IoT devices, embedded systems, and mobile devices. (not symmetric)

Question 4

CCMP

Answer 4

CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol)

A strong encryption protocol used in Wi-Fi networks with WPA2 and WPA3.

Question 5

SRTP

Answer 5

SRTP (Secure Real-Time Transport Protocol)

A secure network protocol used to provide encryption, authentication, and integrity for real-time multimedia communication, securing VoIP calls, video conferencing, and other real-time communications against eavesdropping and tampering.

Question 6

ESP

Answer 6

ESP (Encapsulating Security Payload)

A protocol used to secure data within IPsec tunnels. It encrypts and authenticates data before it is transmitted.
