ECIES has been standardized in ANSI X9.63, IEEE 1363a, ISO/IEC 18033-2, and SECG SEC-1. Shoup's submission can be found at A Proposal for an ISO Standard for Public Key Encryption (v2.1)

Unlike ECIES (which creates a Temporary Public Key V for each cipher text object), AES will require salt to randomize the keys. 4 bytes of random salt is added below. This changes the encryption operation as follows. CryptoPP::RandomNumberSource( rng, 4, true, new CryptoPP::StringSink( SaltText ) ); // RandomNumberSource.
