| Sep 18, 2019 at 21:10 | comment | added | Maarten Bodewes♦ | Yeah, I was talking about AES-GCM, not just AES. Maybe I should have called it a "scheme" instead of an algorithm. OTOH, GCM is certainly not a protocol, that's higher level and would include the RSA encryption. | |
| Sep 18, 2019 at 7:22 | comment | added | Maeher | @CaoTuan unless the key is previously established in an authenticated manner, the authentication of GCM is meaningless. It only attests that the ciphertext wasn't modified. It provides no guarantee that the ciphertext (and key) were produced by any specific entity. | |
| Sep 18, 2019 at 1:43 | comment | added | Cao Tuan | AES is an cryptographic algorithm. But AES-GCM is ian authenticated encryption algorithm. AES-GCM uses an authentication tag that can be used to verify the integrity of the data. The encrypted text contains the IV, ciphertext, and authentication tag. | |
| Sep 17, 2019 at 13:00 | comment | added | Maarten Bodewes♦ | A secure algorithm doesn't make a secure protocol. As anybody can encrypt with the public key from B, it isn't possible to verify that the secret key was generated by A. If the secret key cannot be trusted, then the ciphertext can not be trusted to be from the correct entity either. | |
