#25 RC4 Algorithm - Block Cipher Algorithm |CNS|

[@linguafranca7834]

RC4/ARC4/ARCFOUR is a fast, simple encryption algorithm developed in 1987 to implement byte-by-byte encryption using 64 or 128 bits long keys. RC4 is widely used in Transport Layer Security, Secure Sockets Layer, and the IEEE 802.11 WLAN standard.

Excellent mam.Its really good.

[@rajesh-ke1uc]

Really very easy to understand it's very very useful mam.. Thanks a lot 🙏🙏🙏🙏🙏🙏

In RC4 encryption for the DMR system we use this protocol, after the use of the two algorithms KSA and PRGA resulting from applying them to the private key, plus the initialisation vector we get a keystream, the encryption as such is the result of performing an XOR of this keystream and the voice in clear, taking into account that in each super frame the initialisation vector is modified. The question is the following, if I have the encrypted voice, against which element should I perform this XOR to the encrypted voice if I do not know the key and therefore, the keystream.

Change speed to .75 and lesson will be way more relaxed and understandable. 👍🏽

[@Prakyy]

surely you mean 1.75x

[@rising_star17]

idhar 2x kam pad raha hai

[@ChiruBillion]

we dont hv time brother

[@shashivarun]

Mean while me: got bored of 2x , youtube need to add more than 2x 😂

[@habitamuminwuyelet]

your explanation is very nice please release all lecture form chapter one up to the last chapter

[@abhirampendli7245]

mam it is really good but why dont you start start data mining

[@chathurikadewmi2907]

mam, your explanation is excellent.💖 But in video description why its mention as Block cipher algorithm?

[@online_fun_Bro]

Mam plz explain RC5 ......

[@TroubleFreevideos]

That’s very complicated and lengthy planning to do it in the last

[@divyakothare2238]

yes mam,explain rc5

[@anuhya9013]

Please explain RC5 mam

[@ankithaeeke2912]

Mam where is your example video for rc4

[@varshiniarige3346]

Nyc explanation

[@nghnino]

Very good

[@danielpauljcs]

Thanku for uploading 😀🙏

[@joseAn-b2q]

A question against which I have to XOR the encrypted frame to return the keystream.

[@saya._Za]

Thank u ma'am

[@Ashx321]

aapne to badi jaldi padhai start kar di :)

[@Tarunkumar-hs9wv]

Mam please make a on RC5 Its too imp as of now because we have exam on 20th of January

[@Manishkumar-mi9ji]

Mam where is yhe example

[@tharunkumarreddy9284]

Mam tell about rc5 algorithm

[@TroubleFreevideos]

Okay sure

[@sairamvelpula7566]

Rc5?

In key scheduling, initially we took j=0 for 1st step but what about j value in 2nd step while i=1. Mam

[@anushkrishnan7910]

This is my doubt tooo

[@Shiva-ef4vv]

What abt RC5 ma’am ? Is it imp for Exam ?

[@mdaseersarwar5028]

mam you left RC5 algorithm

Mam can to upload video about RC5 algorithm

[@shivanireddy31]

Ma'am explain RC5 algorithm

[@rasumallakhoushikraj1337]

Ma'am Rc5 algorithm also explain ma'am i hv exam on coming week

[@naveendevaruppala555]

Can u please explain rc5 algorithm

[@yosaroj]

bhai pehle rc4 krle fir puch

[@jayd1030]

is'nt the RC4 a stream cipher?

[@climpZ_7k7]

yep

[@aaratprasadchopra3255]

In the second step, shouldn’t the i and j mod operations be 4 (i = (i+1) mod 4) as per your example or is it always 256 (i = (i+1) mod 256)? at 7:18

[@reemaroychaudhary3882]

why u didnt give the CT answer? Why so fast..

[@UdayKumar-yp4vh]

Pls explain RC5 mam

[@priyankasaini7204]

But RC4 is a stream cipher.

Where is the next video????
