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 For example, the sender’s certificate may have expired, it may have been revoked by the certificate authority, or the server that verifies the certificate is unavailable.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.

TITA100 specifications

The HTC TITA100, commonly known as the HTC Touch, made its debut in 2007 as one of the leading devices that merged mobile phone capabilities with touch-screen technology. This device epitomized the transition towards more intuitive user interfaces, making it a landmark in HTC's lineup of smartphones.

At its core, the HTC TITA100 is powered by Windows Mobile 6.0 Professional, offering users a familiar interface that bridged the gap between traditional mobile phones and smartphones. The device boasts a sleek design, with a vibrant 2.8-inch TFT touchscreen display capable of supporting 65,536 colors. This allows for bright and vivid visuals, making browsing, texting, and multimedia consumption enjoyable.

One of the standout features of the HTC TITA100 is its TouchFLO technology, which allows users to navigate their device smoothly through finger gestures. This was an innovative departure from the stylus-dependent interfaces of its time, making it more user-friendly and accessible. The intuitive nature of TouchFLO enabled quick access to contacts, emails, and applications, enhancing the overall user experience.

In terms of performance, the HTC TITA100 is equipped with a 200 MHz Qualcomm MSM7200 processor. While this may seem modest by today’s standards, it was competent for its time, providing decent multitasking capabilities and smooth operation of basic applications. The device comes with 128 MB ROM and 64 MB RAM, which was fairly standard, allowing for essential applications without heavy load times.

The TITA100 also includes a 2.0 MP camera, which, while basic, was a functional addition for capturing memories on the go. Users could enjoy photo-taking capabilities, complemented by digital zoom and various shooting modes. The device supports microSD expansion, allowing users to increase storage, which is vital for music and video files as well as additional applications.

Connectivity options on the HTC TITA100 include Bluetooth and Wi-Fi, providing flexibility for users to stay connected whether at home or on the move. The inclusion of GPRS and EDGE technologies enables internet browsing, albeit at slower speeds than what modern users are accustomed to.

The HTC Touch ultimately left a significant mark on the smartphone industry. With its combination of innovative touch technology, integration of multimedia features, and user-friendly interface, the HTC TITA100 set the foundation for many successful devices to follow, paving the way for the modern smartphones we carry today. Its legacy endures as a testament to HTC's commitment to innovation in mobile technology.
