Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the sender can calculate only while possessing the ...
EAX mode (encrypt-then-authenticate-then-translate [1]) is a mode of operation for cryptographic block ciphers. It is an Authenticated Encryption with Associated Data algorithm designed to simultaneously provide both authentication and privacy of the message (authenticated encryption) with a two-pass scheme, one pass for achieving privacy and one for authenticity for each block.

An email was sent to our customers in 2017 warning that AOL Mail would no longer be accessible through third-party apps if connection settings weren't updated by November 7, 2017. If you still haven't done so, update your connection settings now. Verizon.net customers: Learn how to update connection settings for your accounts.
SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet. It helps protect your account from hackers and insures the security of private data sent over the Internet, like credit cards and passwords. How to tell if SSL is being used. Look for the "s" in the start of the Web address:
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
The authentication can be performed using either pre-shared key (shared secret), signatures, or public key encryption. [12] Phase 1 operates in either Main Mode or Aggressive Mode. Main Mode protects the identity of the peers and the hash of the shared key by encrypting them; Aggressive Mode does not. [10]
A cipher suite is as secure as the algorithms that it contains. If the version of encryption or authentication algorithm in a cipher suite have known vulnerabilities the cipher suite and TLS connection may then be vulnerable. Therefore, a common attack against TLS and cipher suites is known as a downgrade attack. A downgrade in TLS occurs when ...
