Thank you so much sir 🤩Your teaching is truly excellent sir😇
It's my pleasure. Keep learning and keep sharing..
👍🏻
18:52 sir ithoda dimension epputi 1x4 varum oru column thana Iruku so 4x1 thana varanum appudi vantha another constant 4x4 kuda multiply panna mudiyathe sir
Yes you are right but during processing we take the column out and transform it and then perform operation. Thats why.
@because2022 ok sir thank you
at 19:46 you said we need to multiply witha constant 4x4 matrix..can we consider that 4x4 matrix as as the first matrix which we formed initially from our input message?
No in the same timestamp, you will see a 4* 4 matrix in top starting with row 1 (2,3,1,1). That matrix is taken for this example
ok sir thank you@@because2022
Keep on rocking sir
Thanks a lot

Sir in step substitution that values of second table where did u get and first table is output of preprocessing that second table what
Please mention timestamp of doubt too

6:17. Key expansion algorithm la frst 4 key soldreengaley pruila
Key expnasion algorithm gives very long key. We take only first four words. You can take random for explaining also.
rombha nandri sir
Most welcome. Keep learning and keep sharing.
Sir for sdes algo sums.. Initial permutation, expansion perumutation...sbox..will these values be present in the log book?
They wont ask sums in DES 99%.

sir just concept crct ha eludhana podhum la sir ? or we need to give crct answer for encyrption stpes
Concept is more important and write maximum steps possible.
Will the s box table be given in exam sir?
No not required. Jst explain panuna pothum.
Thanks a lot mam❤

no.
@because2022 so random values use pannalama?
@@datainfo5986 Yes
Xor pandrathuku anga irukura table la values laa eppadi mam (6:30) vandhuchu??
You can take random values too. But it would be from key expansion algo.
@@because2022 then the substitution table mam??? How I should memorize that??
You can take random values also to expalin. Mam ila sir than..@@Candys_vlog

Sir,aes sum ma keppangala sir?
Chances are v less..
Sir inner calculation yala correct aa irukanuma ila randoma podalama
Any random values too.
Mam idhula S box memory panna numa
NO
so if they ask write the aes alg ? namma fulla eludhanum ah sir indha example vece and inside irruka binary value lam random ah podalama something random number values sollunga sir
Yes you need to write in full and binary values random a eluthalam.

Construction is given in book but it is not that much important. You can study if required.
