[Cisspstudy] Encryption methods (please work with me on this one)

[Ashraf Amin]

Greetings,

Block ciphers & Stream-Based are the two methods of cryptography

Symmetric & Asymmetric are two forms of cryptography  

(ISC2) Official Page 236

Point is, what if you have a question that goes like:

What are the most important encryption methods:

1. symmetric, asymmetric

2. block, stream

It is a BAD question I know but still I am sure I rember I had a question like this one somewhere.

Moreover, is this the likely to be the level of trickery the CISSP can present ? Unfortunately I don't know and this is the reason why I am scratching my head everytime I find inconsistences.

Methods is a flexible term and can be used in many ways when referring to crypto.

Clement, list -
I do understand the the official guide is clearly not accurate. Words cannot describe how angry I am...Nevertheless - at least for my own peace of mind - I would like to throw another one from the guide:

" Encryption methods"

Shon Harris AIO - Page 679

"Methods of encryption"

As far as I can say as for as Shon is concerned 'methods' refers to symmetric vs. asymmentric

Official ISC2 guide - Page 227

"Methods of Cryptography"

Here for "methods" the author refers to block vs stream ciphers

Thanks,
Andrea
