CISSP Domain 3 Review / Mind Map (6 of 9) | Cryptography

[@destcert]

We wrote a CISSP guidebook! Check it out here: destcert.com/guidebook/

[@ncgolfer99]

Rob is the best. No Adam Gordon or Kelly or anyone else. Rob has a great voice too. A lot of work has been put in for these videos. Thanks!

[@Resilient1401]

I can say the Destination Certification are best of CISSP videos in KZbin :)

[@destcert]

😳 thanks!

[@Leonardbanks718]

Hey Rob, I don’t know if you’ll ever see this but due in large part to your CISSP mind map series, i have provisionally passed the CISSP exam today. I just want to give a huge thank you!

[@destcert]

Hey Leonard, Rob here. Congratulations on passing the CISSP exam! Well done! And thanks for letting me know the MindMaps helped you in your achievement. Very rewarding to hear!

[@raghavendrankr4466]

This is a MUST to use resource for anyone preparing for CISSP. The way Rob speaks was very clear and very easy to follow. I liked the Visuals and were truly helpful to create a map in mind for each topic. I used these maps after finishing the OSG and Destination CISSP Book. Though this is Free, they did not compromise on quality of content. I cleared my CISSP on May 2023. Thank you very much for making that happen.

[@arifshaikh213]

I have been struggling to understand cryptography for the last 3 days and I finally you nailed it.... thanks so much for the video

[@Rajeshsharma-fb1dn]

Best videos on KZbin for CISSP, You are champ. Even i haven't appeared for the exam but if i pass sure 50% credit goes to you thanks

[@destcert]

Thanks! I'm sure you'll rock the exam when you take it!

[@iainspirit4711]

I've been trying to get this to sink in for literally years and this has finally done it! Had to pause and rewind a couple of times reread my notes but its there! ask my about symmetrical and asymmetrical encryption! Thank you.

[@jesse8117]

You somehow make learning about encryption extremely interesting. Thank you for making these videos! You're a hero!

[@mikekorsak373]

You are SOLID and so helpful, just cannot say enough about your ability to simplify and quickly summarize lots of information.

[@destcert]

That's great to hear! Glad it was helpful!

[@t.m.2235]

Thanks!

[@aayushbhusal9297]

Finally a new video..I am taking my exam in a month..i hope you get domain 4 and remaining domain 3 videos by then!!

[@clairehan7535]

Thank you for explaining something so complex and convoluted so simply!

[@MillionairesClub2023]

Notes Encryption --Methods >Substitution & Transposition --Types >One way encryption hash & two way encryption --Two way encryption > symmetric and asymmetric --Symmetric >Block cipher (DES,3DE,AES,Blowfish,Twofish and stream cipher(RC4) --Block cipher modes -ECB,CBC,CTR & Stream cipher is produced after xoring plain text with a key. --Asymmetric>Discreet logic (DH,ECC,EL GAMAL) &Factorization of large prime no( RSA)

[@ksaholy]

A picture is worth a thousand words. wonderful. Thanks

[@lavanyadhanasekar3215]

Appreciations Rob!! This is very helpful to me as a growing bud. Going to attempt the exam soon.. expecting more videos to come..

[@phennexion]

15:48 thanks, i was starting to glaze over, needed that.

[@uroojbaig5598]

Fantastic Explaination as always Rob :) One thing I noticed is at duration 20:46 seconds, the Spartan Scytale is a Transposition Cipher, but in your slide its mentioned as 'Substitution'

[@destcert]

Good catch! It should definitely say transposition for the Scytale.

[@SecuritywithSandy]

I couldn't RESIST the urge to comment!

[@destcert]

haha! Well done :)

[@socialimpact2094]

Thank you for this “ nice & well organized “ video 👍👍👍

[@mastmaula123]

This is the best video on cissp prep

[@LJHAGH]

Love these videos! Great work, Rob!

[@klaushu7547]

cannot wait to see the next two series. They are my weakest points

[@MegaJusttosee]

Great effort Rob. Thank you so much

[@destcert]

Thanks! My pleasure!

[@bjaMoke]

Another solid video run.

[@edwardsolomon34]

Amazing works gentlemen!

[@destcert]

Thanks!

[@mustafaabubakar293]

Thank you for your effort to prepare this video, it helps me alot to recall the subjects and easy to remember.

[@VrushaliDharmadhikari]

These videos are fantastic!! Helping a lot in CISSP prep Are you going to do Domain 4?

[@getsheela123]

Hi, thanks for the excellent video. I am unable to find the Free Mini Masterclass videos that you mentioned. Where can I find the link for the same

[@stgadmin]

Amazing and easy to understand!

[@chrisadams27]

This is great thank you

[@singlediary]

i got this question, what type of cipher is? Alan intercepts an encrypted message and wants to determine what type of algorithm was used to create the message. He first performs a frequency analysis and notes that the frequency of letters in the message closely matches the distribution of letters in the English language.

[@klaushu7547]

great training video. Could you share the mind maps of CISSP domains through email or any other means? Would love to receive it

[@mototodd]

Do you video tape all the scenes with people yourself? If so that must take a long time because they are very high quality.

[@don.p3271]

The resignation letter has an null cipher of RESIST.

[@ahmetkamilorman6162]

there is a confusion i guess. although they use block cipher, cfb and ofb works in stream mode. thanks for the great videos by the way.

[@chrischeong7626]

Thanks alot for the hard work done in creating ALL these videos. I've looked thru the CISSP notes from CYBRARY (Kelly Handerhan) - which has the following description on "Avalanche": Avalanche (chaining) -> when output from one function provides input to the next But I still prefer to stick to your explanations b/c I also see a similar explanation via "IT Dojo" on his CISSP Questions of the Day

[@estrategiaygestiondecibers1673]

Excelente

[@redsoxwinagain2007]

If you struggle with crypto, dig in a little more into the history of it. It will provide you with the greatest foundation to understand it.

[@longfieldchrono770]

I have to agree with the above - these are bloody fantastic. but i need MOOOOOORE!....7/9 ? plaeaeaasaaasae..

[@destcert]

Working on them!

Null Cipher = RESIST ?

Great !!!!!!

[@PoonamSingh-vy1yn]

Awesome

[@sporteewale]

The message in the resignation letter is "RESIST".😀

[@Stingray55]

Necessary Keys for Symmetric Encryption (Formula) is wrong in the video. Should be N(N-1)/2.

[@destcert]

Yes, you're right. I see that the text in the transcript was wrong. Fixed to correctly show the formula is N(N-1)/2. Good catch @Stingray55

[@Stingray55]

@@destcert thank you for updating that. I appreciate all the effort you've put into this channel. I'm sitting in a couple of days and this channel has been a big help.

[@shawnafranke9624]

RESIST!!

[@airminghk]

Spartan Scytale is neither substitution nor transposition since it only takes subset of the alphabet from a long word. No replacement of characters. No re-ordering.

[@ranjuputta61619]

The formula used for finding the symmetrical keys w.r.to. number of users = N*(N-1)/2 This formula is not clear, anyone can please explain this?

[@gabrielgarcia-xo5xy]

N = The number of people in the question. How many symmetric keys do 3 people need? 3(3-1)/2 = 3.... 4 people 4(4-1)/2 = 6

You got it!

I figured if you took the time to create these well planned out mind maps, and added a game to it to make it more interesting then the least I could do is take the time to find the secret message. I appreciate your work
