Hello student, the provided scheme of using the md5 hash of the sanda number as iv initialize vector of the yeast sector in cbc mode.
00:10
Encryption doesn't ensure a secure and random iv generation.
00:15
The security of the iv is crucial in maintaining the confidentiality and integrity of the encrypted data.
00:23
Let's examine the options.
00:25
No, an attacker can use a watermarking attack to confirm that you are using this scheme.
00:33
So here i will go this statement is true.
00:43
The repeated use of the predictable ivs such as those derived from the sanda number can potentially provide attackers with an opportunity to identify the encryption technique being used thus compromising the security of the system.
01:00
So this is true.
01:02
B option is yes, the mds algorithm introduced enough randomness into the iv.
01:09
So this statement is not accurate.
01:12
This statement is not accurate.
01:20
So while md5 does introduce some randomness using it to directly generate ivs can still result in predictable patterns, especially when the input space has the limited variability.
01:35
So this statement is not accurate.
01:37
Third statement is no attacker can use a watermarking attack to recover the encrypted data...
