8.5 E-mail Security

Windows Mobile protects your Outlook e-mails through Secure/Multipurpose Internet Mail Extension (S/MIME), which allows you to digitally sign and encrypt your messages.

Digitally signing a message applies your certificate with the authorization key to the message. This proves to the recipient that the message is from you and not from an impostor or a hacker, and that the message has not been altered.

Encryption protects the privacy of your message by converting it from plain, readable text into cipher (scrambled) text. Only the recipient who has the authorization key can decipher the message.

Requirement S/MIME encryption and digital signatures for Windows Mobile-based devices are available only with Exchange Server 2003 SP2 or a later version that supports S/MIME. If your company is not using

one of these products, or you have not completed your first synchronization with the Exchange Server, these options are unavailable.

Note You can encrypt a message with or without a certificate. However, to read an encrypted message, you need a valid certificate to decrypt it.

To individually sign and encrypt a new message

1.Tap Start > Messaging > Outlook E-mail.

2.Tap Menu > New to create a new message.

3.Tap Menu > Message Options.

4.From the Security list, select whether to encrypt only, sign the message only, or do both.

5.Tap OK.

To verify the digital signature on a signed message you receive

1.Open the Outlook e-mail message that has been digitally signed.

2.At the top of the message, tap View Signature Status.

3.Tap Menu > Check Certificate. To view the details of the certificate in the message, tap Menu > View Certificate.

Note There can be several reasons why a digital signature is not valid. For example, the sender’s certificate may have expired, it may have been revoked by the certificate authority, or the server that verifies the certificate is unavailable. Contact the sender to report the problem.

To digitally sign and encrypt all messages

You can set up ActiveSync to digitally sign and encrypt all outgoing messages. You must obtain a valid certificate to sign and encrypt e-mail messages successfully.

1.Tap Start > Programs > ActiveSync.

2.Tap Menu > Options.

3.Select the E-mailinformation type, and tap Settings. On the E-mail Sync Options screen, tap Advanced.

4.Do one or both of the following:

To sign all your outgoing e-mail messages so that recipients can be certain that the messages were sent by you and have not been altered in any way, select the Sign all outgoing e-mail messages check box.

To encrypt all your outgoing e-mail messages so that the contents of your messages are protected from being viewed by anyone other than the intended recipients, select the Encrypt all outgoing e-mail messages check box.

VOGU100 specifications

The HTC VOGU100, often recognized by its brand name, the HTC Touch, was a standout smartphone released in 2007. This device marked a significant step in mobile technology, embracing the touchscreen trend at a time when many competitors relied heavily on physical keyboards. The VOGU100 was particularly celebrated for its innovative features and user-friendly interface.

One of the hallmark characteristics of the HTC VOGU100 is its 2.8-inch resistive touchscreen display. The resolution of 240 x 320 pixels offered a clear and vibrant viewing experience, allowing users to navigate through apps and media with ease. The capacitive nature of the touchscreen allowed for basic fingertip control, though it was not as responsive as the later capacitive displays.

Powered by Windows Mobile 6.0, the HTC VOGU100 offered users the familiarity of a PC-like environment on their phones. This operating system allowed for a range of applications to be installed, providing flexibility and customization. Additionally, the TouchFLO user interface overlaying Windows Mobile enhanced the usability of the device, making navigation smoother for the average user.

The HTC VOGU100 was equipped with a Qualcomm MSM7200 processor running at 200 MHz, supported by 128 MB of RAM and 256 MB of internal storage. The inclusion of a microSD slot meant that users could expand their storage, making it easier to manage personal data, photos, and applications.

An integrated 2-megapixel camera allowed users to capture images and short videos, although the quality was relatively basic by modern standards. Additionally, the device supported Bluetooth 2.0 and Wi-Fi connectivity, enabling users to stay connected and share data with ease.

Another notable feature of the HTC VOGU100 was its compact design, which measured 102 x 58 x 15 mm and weighed just 112 grams. This lightweight and slim profile made it easy to carry, appealing to smartphone users who valued portability.

In summary, the HTC VOGU100, with its touchscreen interface, solid performance metrics, and user-friendly features, represented a pivotal moment in the evolution of smartphones. While its technology may seem antiquated by today’s standards, it laid the groundwork for future innovations in mobile devices, marking HTC's commitment to pushing the boundaries of mobile technology.
