Multiple Encryption and Triple 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

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.

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

Please provide the numericals sums and solutions for Double DES.

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

can you please provide blowfish concept sir

🎉🎉

❤❤

i dont think double DES you have explained is correct
