Here is a list of features of a block cipher mode. select all that apply to the ctr mode.
Show Introduction to Block Cipher modesThere are five types of operations in block cipher modes, ECB (Electronic Code Block) mode, CBC (Cipher Block Chaining) mode, CFB (Cipher Feedback) mode, OFB (Output Feedback) mode and CTR ( Counter) mode. Where ECB and CBC mode works on block ciphers, and CFB and OFB mode works on block ciphers acting as stream ciphers. ECB is used for transmitting a single value insecure manner, CBC is used for encrypting blocks of text authentication, CFB is used for transmitting an encrypted stream of data authentication, OFB is used for transmitting an encrypted stream of data, CTR is used for transmitting block-oriented applications. Block cipher modes of operationThere are 5 modes of operation in the block cipher. 1. ECB mode
2. CBC Mode
3. CFB Mode
4. OFB mode
5. CTR Mode

What are the characteristics of block ciphers?A block cipher is an encryption method that applies a deterministic algorithm along with a symmetric key to encrypt a block of text, rather than encrypting one bit at a time as in stream ciphers. For example, a common block cipher, AES, encrypts 128 bit blocks with a key of predetermined length: 128, 192, or 256 bits.
What is CTR mode in cryptography?The Counter Mode or CTR is a simple counter-based block cipher implementation. Every time a counter-initiated value is encrypted and given as input to XOR with plaintext which results in ciphertext block. The CTR mode is independent of feedback use and thus can be implemented in parallel.
Which of the following are block cipher modes?Block Cipher Modes
As summarized on the Current Modes page, there are eight confidentiality modes (ECB, CBC, OFB, CFB, CTR, XTS-AES, FF1, and FF3), one authentication mode (CMAC), and five combined modes for confidentiality and authentication (CCM, GCM, KW, KWP, and TKW).
What are some common block cipher modes?There are five types of operations in block cipher modes, ECB (Electronic Code Block) mode, CBC (Cipher Block Chaining) mode, CFB (Cipher Feedback) mode, OFB (Output Feedback) mode and CTR ( Counter) mode.
