A random private key of 64 (hex) characters (256 bits / 32 bytes) is generated first.
A 128 (hex) character (64 bytes) public key is then derived from the generated private key using Elliptic Curve Digital Signature Algorithm (ECDSA).
The Keccak-256 hash function is then applied to (128 characters / 64 bytes) the public key to obtain a 64 character (32 ...

Any suggestions for an architecture to reach to Bitcoin's wallet structure for Ethereum?
My suggestion is don't. Ethereum is not a UTXO blockhain, but an account-based one. Any Bitcoin like wallet structure on Ethereum is not practical, or not needed.
For creating a hot wallet please see this answer.

This can be done with signatures. In general the idea with private and public keys is that nobody knows the private key, but everyone know the public key (duh :P). In Ethereum the address of an account is derived from the public key. So you could require the user to submit the signature of some data and recover the address from it (see ecrecover) to perform ...
