Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...
If you no longer have your Security Key, use these steps: Go to the Sign-In Helper. Sign in and go to the AOL Account Security page. Turn off Security Key 2-Step Verification. When you get your Security Key back or get a new key, you can re-enable 2-Step Verification in your Account Security settings.

With iMazing, an iPhone or iPad can be used similarly to an external hard drive. [4] [7] It performs tasks that iTunes doesn’t offer, [1] including incremental backups of iOS devices, browsing and exporting text and voicemail messages, managing apps, encryption, and migrating data from an old phone to a new one.

A cryptographic key is called ephemeral if it is generated for each execution of a key establishment process. [1] In some cases ephemeral keys are used more than once, within a single session (e.g., in broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is combined separately with each recipient's public key.
A session key is a single-use symmetric key used for encrypting all messages in one communication session.A closely related term is content encryption key (CEK), traffic encryption key (TEK), or multicast key which refers to any key used for encrypting messages, contrary to other uses like encrypting other keys (key encryption key (KEK) or key encryption has been made public key).
