CBC has the advantage over the ECB mode in that the XORing process hides plaintext patterns. Even if the first plaintext block and third plaintext block were the exact same segment of plaintext, it is highly unlikely that the first ciphertext block and third ciphertext block would be the same.Key Differences Between ECB and CBC
The Electronic Code Book (ECB) mode uses basic substitution, making it one of the most straightforward and efficient algorithms to implement. CBC (cipher-block chaining) is an AES block cipher mode that improves the ECB mode for minimizing patterns in plaintext.The disadvantage of this method is a lack of diffusion. Because ECB encrypts identical plaintext blocks into identical ciphertext blocks, it does not hide data patterns well. ECB is not recommended for use in cryptographic protocols."
What are the pros and cons of ECB : Each mode of operation has its pros and cons. For example, Electronic Code Book (ECB) mode is the simplest mode of operation. With ECB, each block is encrypted completely independently. The downside of this is that blocks with the same plaintext produce the same ciphertext.
Why is CBC better
It focuses on real-world applications, critical thinking, problem solving and holistic development. This more personalised learning approach encourages students to progress at their own pace. Assessments in the CBC focuses on the continuous evaluation of students' competencies and skills.
What is the weakness of CBC mode : CBC has been the most commonly used mode of operation. Its main drawbacks are that encryption is sequential (i.e., it cannot be parallelized), and that the message must be padded to a multiple of the cipher block size. One way to handle this last issue is through the method known as ciphertext stealing.
The major difference between ECB and CBC is that ECB encrypts each block independently, whereas CBC encrypts each block with the previous block. CBC is therefore considered more secure and resistant to pattern recognition attacks than ECB. The block cipher modes ECB, CBC, OFB, CFB, CTR, and XTS provide confidentiality, but they do not protect against accidental modification or malicious tampering. Modification or tampering can be detected with a separate message authentication code such as CBC-MAC, or a digital signature.
Why ECB mode is not secure
Of the five DES modes, ECB is the simplest and weakest, because repeating plaintext generates repeating ciphertext. As a result, anyone can easily derive the secret keys to break the encryption and decrypt the ciphertext. ECB may also leave obvious plaintext patterns in the resulting ciphertext.Of the five DES modes, ECB is the simplest and weakest, because repeating plaintext generates repeating ciphertext.

ECB provides an opportunity to borrow a large volume of funds for the long term. The cost of funds is usually cheaper if borrowed from economies with a lower rate of interest. ECB allows the borrower to diversify the investor base. CBC could be extremely effective in treating anxiety and depression and combines with THC and CBD to deliver an entourage effect of mood-boosting properties.
Why is CBC good : The complete blood count (CBC) is test, used to diagnose and monitor numerous diseases. It can reflect problems with fluid volume (such as dehydration) or loss of blood. It can show abnormalities in the production, life span, and destruction of blood cells.
What are the disadvantages of CBC : These are some of the CBC challenges that affect the whole system and the government should give priority.
Inadequate teachers training.
Inadequate teaching and learning resources.

Lack of ICT skills and infrastructure.

When to use ECB mode
As discussed above, ECB mode leaks information about the plaintext because identical plaintext blocks produce identical ciphertext blocks. A ciphertext should never leak any information about the plaintext used to create it, so ECB mode is insecure and should never be used. ECB is the simplest and weakest form of DES. It uses no initialization vector or chaining. Identical plaintexts with identical keys encrypt to identical ciphertexts.The problem with CBC mode is that the decryption of blocks is dependent on the previous ciphertext block, which means attackers can manipulate the decryption of a block by tampering with the previous block using the commutative property of XOR.
Is CBC unsafe : However, when using CBC mode, it is essential that it be implemented correctly. Improperly implemented padding of ciphertexts can leave the system vulnerable to attacks like POODLE. While CBC mode is better than ECB, GCM is better than both.
