![]() ![]() Alice encrypts her message into "ZGVleiBudXRz" using the secret password, "1234".Alice wants to send a message to Bob securely.Here's how authenticated encryption could look like when using an unauthenticated encryption mode, like AES-CBC. While encrypted data cannot be directly read by unintended third-parties without the correct decryption key(s), it can be manipulated in certain ways or used in replay attacks, unless encrypted with authenticated modes (such as AES GCM and CCM) or HMACs. Integrity verification, also called " authenticated encryption", in the context of encryption means verifying that the encrypted data received is indeed authentic and not tampered with. This analysis assumes that MEGA has been fully transparent in their cryptography implementations through their public whitepaper.Ĭategory 1: Lack of Integrity Verification Whitepapers are only valid if the company publishing them is transparent. ![]()
