Multiple Encryption and Triple DES

[@subhashishnabajja9563]

Nice video, it was very helpful. But can you explain all the possible attacks on the Triple DES encryption system. It would be very helpful.

[@lakshminarayananallamothu6695]

What happens if there more than one match? Then, How will the attacker comes to know which one is correct intermediate text?

[@HarshaPriyaG-g4h]

Please provide the numericals sums and solutions for Double DES.

00:03 Understanding the drawbacks of DES and exploring multiple encryption and Triple DES
02:22 Multiple encryption enhances security.
04:31 Triple DES involves using K1 and K2 for encryption and decryption
06:35 Triple DES encrypts plaintext to ciphertext and then decrypts it back
08:36 Understanding the vulnerability to meet in the middle attack in double DES
10:42 Once the key is known to the attacker, confidentiality is compromised.
12:44 Attacker uses an exhaustive search to find the intermediary ciphertext.
14:41 Explanation of the meet in the middle attack
16:48 Triple DES involves encryption two times and decryption one time.
18:39 Triple DES uses two keys for encryption and decryption.
20:27 Triple DES has two variations with two keys and three keys

all videos are amzing thankyou

[@adityarajsinhchauhan7151]

I have question you explained triple des with 2 keys but if you encrypt first then decrypt same then again encrypt it is as same as doing single time decryption

[@VijaySimha-jf3mi]

No, because the decryption is done in the second step is with different key when compared to the key used in encryption

i dont think double DES you have explained is correct

[@nniharika6705]

can you please provide blowfish concept sir
