I am looking for a proof for the following two claims from "Serious Cryptography" by Aumasson.

NM-CPA implies IND-CPA. [...] IND-CCA and NM-CCA are equivalent notions that imply the presence of the other.

where IND-CPA/IND-CCA and NM-CPA/CCA are defined as indistinguishability and non-malleability under chosen plaintext/chiphertext respectively.

Where can I find those proofs?

This paper, AFAICT: https://www.cs.ucdavis.edu/~rogaway/papers/relations.pdf

It is about the security of public-key encryption, but the proofs about the relations between security definitions are applicable to symmetric encryption.
