How can I access the message properties on an Outlooko client for Mac? I received a phishing email this past Monday; and I'd like to block the IP Address, in order to access to this I need to access to the message properties of the phishing email, i.e. On Windows I normallyy click on fileProperties, however on the client installed for MAC. The message organization capabilities are impressive and ea. For Mac is a free call and messaging client available for Mac, PC, mobile phones and tablets. If the message was successfully decrypted, you'll see an open lock. If the signature of the message is valid, you'll see a star icon with a checkmark. Make sure to click 'Details' to see the security header. Signed messages. Will show the email address associated with your friend's key that was used to sign this message.
- The number of lines of the message to show in the message list. Move discarded messages into. Choose whether to move the messages to the Trash mailbox so you can delete them or move messages to the Archive mailbox when you swipe left on a message in the message list. This setting also determines whether you can delete or archive messages from Mail notifications.
- The Apple mail is the default Mac mail client for Mac OS X. With Mavericks, the latest OS X, the mail comes free of cost. Some of the features of this email client are mentioned below. Advanced search features based on the attachments and attachment types. Support for Microsoft Exchange accounts.
An XMPP client is any software or application that enables you to connect to an XMPP for instant messaging with other people over the Internet. There are many free clients you can use to do this, for many different devices and operating systems.
Note: The following software was not developed by the XMPP Standards Foundation and has not been formally tested for standards compliance, usability, reliability, or performance.

In the last chapter, we discussed the data integrity threats and the use of hashing technique to detect if any modification attacks have taken place on the data.
Another type of threat that exist for data is the lack of message authentication. In this threat, the user is not sure about the originator of the message. Message authentication can be provided using the cryptographic techniques that use secret keys as done in case of encryption.

In the last chapter, we discussed the data integrity threats and the use of hashing technique to detect if any modification attacks have taken place on the data.
Another type of threat that exist for data is the lack of message authentication. In this threat, the user is not sure about the originator of the message. Message authentication can be provided using the cryptographic techniques that use secret keys as done in case of encryption.
Message Authentication Code (MAC)
MAC algorithm is a symmetric key cryptographic technique to provide message authentication. For establishing MAC process, the sender and receiver share a symmetric key K.
Essentially, a MAC is an encrypted checksum generated on the underlying message that is sent along with a message to ensure message authentication.
The process of using MAC for authentication is depicted in the following illustration −
Let us now try to understand the entire process in detail −
The sender uses some publicly known MAC algorithm, inputs the message and the secret key K and produces a MAC value.
Similar to hash, MAC function also compresses an arbitrary long input into a fixed length output. The major difference between hash and MAC is that MAC uses secret key during the compression.
The sender forwards the message along with the MAC. Here, we assume that the message is sent in the clear, as we are concerned of providing message origin authentication, not confidentiality. If confidentiality is required then the message needs encryption.
On receipt of the message and the MAC, the receiver feeds the received message and the shared secret key K into the MAC algorithm and re-computes the MAC value.
The receiver now checks equality of freshly computed MAC with the MAC received from the sender. If they match, then the receiver accepts the message and assures himself that the message has been sent by the intended sender.
If the computed MAC does not match the MAC sent by the sender, the receiver cannot determine whether it is the message that has been altered or it is the origin that has been falsified. As a bottom-line, a receiver safely assumes that the message is not the genuine.
Limitations of MAC
There are two major limitations of MAC, both due to its symmetric nature of operation −
Establishment of Shared Secret.
It can provide message authentication among pre-decided legitimate users who have shared key.
This requires establishment of shared secret prior to use of MAC.
Inability to Provide Non-Repudiation
Non-repudiation is the assurance that a message originator cannot deny any previously sent messages and commitments or actions.
MAC technique does not provide a non-repudiation service. If the sender and receiver get involved in a dispute over message origination, MACs cannot provide a proof that a message was indeed sent by the sender.
Though no third party can compute the MAC, still sender could deny having sent the message and claim that the receiver forged it, as it is impossible to determine which of the two parties computed the MAC.

Both these limitations can be overcome by using the public key based digital signatures discussed in following section.
