Encryption is used to encrypt traffic between two points, and can be used for files, data streams or together with authentication to ensure END to END the data and authentication is secure. Adrian Cantrill Solutions Architect Authentication is usually done by a username and password, and sometimes in conjunction with factors of authentication, which refers to the various ways to be authenticated. Authentication factors determine the various elements the system use to verify one’s identity prior to granting him access to anything from accessing a file to requesting Identity Based Encryption (IBE). Identity-based encryption is a type of public-key encryption in which a user can generate a public key from a known unique identifier such as an email address), and a trusted third-party server calculates the corresponding private key from the public key. Whether and how it provides secure authentication and data encryption depend heavily on what underlying mechanism is used within this framework. Here is an example from the svnserve documentation: "The built-in CRAM-MD5 mechanism doesn't support encryption, but DIGEST-MD5 does". Technical Note: Authentication and other uses of encryption that are not controlled. Category 5, Part 2 of the Commerce Control List covers items designed or modified to use cryptography that employ digital techniques and perform any cryptographic function other than authentication, digital signature, or execution of copy-protected software (including their associated key management function). Encryption is supported by SSL and it acts by remolding the plaintext data (i.e. normal text) into ciphertext (i.e. converted text in unreadable format). SSL provides confidentiality to data with an encryption technique known as symmetric encryption, where both the encryption and decryption are done by a single public key. IPsec supports two encapsulation types. The first one is AH (Authentication Header) which as the name implies, authenticates the header. The other encapsulation type is ESP (Encapsulating Security Payload) which encrypts packets. We can use both for OSPFv3 so besides authentication, encryption is also a possibility.

As encryption is being done on the sender’s station rather than the C-Series box, the sender must install the IronPort PXE Encryption Plug-in (for Outlook or Lotus Notes). Advantage of Endpoint to Endpoint Encryption. Provides the highest level of encryption with the additional benefits of Business Class Email. When a client SSL certificate is involved, the authentication that occurs during the handshake goes both ways. Client SSL certificates also have a public/private key pair associated with them — though, in this case, it’s entirely for authenticating the signature, not encryption. The server handles the encryption. For information about configuring certificates and activating SSL, see "Managing Authentication and Encryption" in the Directory Server Administration Guide. Certificate-Based Client Authentication When establishing encrypted connections over SSL or TLS, you can also configure the server to require client authentication .

However, without any form of authentication (e.g. a fully transparent authentication loading hidden keys), encryption provides little protection from advanced attackers as this authentication-less encryption fully rely on the post-boot authentication comes from Active …
