Talk:SIM-CCA security

From CRYPTUTOR

Pictures are taken and modified from the pictures in SIM-CPA security. --Fiona

In the Chosen Ciphertext Attack example: say that it's an attack on Elgamal encryption scheme; change $e'\,$ to $m'\,$ , and replace 36 by say $x\,$ .
Expand on the definition of SIM-CPA security, explaining the Real and Ideal world experiments in detail (like in SIM-CPA security).

--Manoj

Changed the first bullet. Will do 2nd bullet later. --Fiona

Done, unless told otherwise. --Fiona

Can you make more clear the purpose of the first section? I.e, CPA security is nice but doesn't capture every kind of attack (for instance consider the following attack...). Then say that CCA is an attempt to capture a wider range of things.

Changes made... -Fiona, 12/14
