I've seen some papers drawing a connection between IND-CPA and passive attacks and IND-CCA and active attacks. Can someone explain how IND-CPA relates to passive attacks and IND-CCA relates to active attacks if this is indeed the case?
The most recent example of such a paper that I can recall is this: https://eprint.iacr.org/2020/1533
Another example is this excerpt from the preface of Introduction to Modern Cryptography, 3rd edition (http://www.cs.umd.edu/~jkatz/imc.html):
"We have divided our treatment of symmetric-key encryption into two parts: Chapter 3 deals with security against “passive” attacks (i.e., CPA-security), while Chapter 5 addresses “active” attacks (i.e., CCA-security and authenticated encryption)."
