ECIES is must with Symmetric?(ECIES-AES or ECIES-TDES) I can't understand the ECIES algorithm.

I saw two different ECIES algorithms:


Using only Public key

Key generation:

$A_{pri} : n_A$
$A_{pub} : n_A G$  

$B_{pri} : n_B$
$B_{pub} : n_B G$

Encryption:

Select a random $k$.

A -> B to Cipher C : $\{kG, \text{message} + k B_{pub}\}$

Decryption

$\text{message} + k B_{pub} - n_B kG = message + k n_B G - n_B k G = \text{message}$
Using Symmetric key(AES)


what is real?
Yes, ECIES is essentially a more practical implementation of ElGamal, a hybrid cryptosystem.  It uses symmetric encryption following an ephemeral key exchange.   

Refer to : https://en.wikipedia.org/wiki/Integrated_Encryption_Scheme

Compare it with : https://en.wikipedia.org/wiki/ElGamal_encryption

The only difference is that instead of using KDF+XOR or AES+GCM as the symmetric cipher, ElGamal specifies a different symmetric step mapping the message to a point and using inverse modulo to recover.   

Once of the oddities is that using a KDF and then using XOR was the most popular version of ECIES for a number of years.   If used carefully, it's OK, but without properly padding the message, things can get ugly (chosen ciphertext attacks, etc.)

Ditching XOR and using AES/GCM with the shared secret seems, to me, like the better move, shifting responsibility for the authentication onto the symmetric layer.  The use of KDF/XOR is still prevalent in modern libraries, mostly because some XOR variants were FIPS certified.
