White Paper Z600

Security using the WAP

For certain WAP services, such as banking serv- ices, a secure connection between the phone and WAP gateway is necessary. An icon in the display of the Z600 indicates when a secure connection is in use.

The Z600 is based on the WAP 2.0 (WML 1.3) specification suite, in which security functionality is specified by a technology called Wireless Transport Layer Security (WTLS). The WAP protocols for han- dling connection, transport and security are struc- tured in layers, with security handled by the WTLS layer, operating above the transport protocol layer. WTLS classes define the levels of security for a WTLS connection:

•WTLS class 1 – encryption with no authentica- tion.

•WTLS class 2 – encryption with server authenti- cation.

•WTLS class 3 – encryption with both server and client authentication.

Server authentication requires a server certificate stored at the server side and a trusted certificate stored at the client side.

Client authentication requires a client certificate stored at the client side and a trusted certificate stored at the server side.

A Wireless Identity Module (WIM) can contain both trusted and client certificates, private keys and algorithms needed for WTLS handshaking, encryp- tion/decryption and signature generation. The WIM module can be placed on a SIM card and is then referred to as a SWIM card.

Certificates

To use secure connections, the user needs to have certificates stored in the phone. There are two types of certificates:

Trusted certificate

A certificate that guarantees that a WAP site is gen- uine. If the phone has a stored certificate of a cer- tain type, it means that the user can trust all WAP gateways that use the certificate. Trusted certifi- cates can be pre-installed in the phone, in the SWIM or they can be downloaded from the trusted supplier’s WAP page.

Client certificate

A personal certificate that verifies the user’s iden- tity. A bank that the user has a contract with may issue this kind of certificate. Client certificates can be pre-installed in the SWIM card.

WIM locks (PIN codes)

There are two types of WAP security locks (PIN codes) for a SWIM, which protect the subscription from unauthorized use. The PIN codes should typi- cally be provided by the supplier of the SWIM.

Access lock

An access lock protects the data in the WIM. The user is asked to enter the PIN code the first time the SWIM card is accessed when establishing a connection.

Signature lock

A signature lock is used for confirming transac- tions, much like a digital signature.

In the Z600, the user can check which transactions have been made with the phone when browsing. Each time the user confirms a transaction with a signature lock code, a contract is stored in the phone. The contract contains details about the transaction.

Configuration of WAP settings

An easy way to perform WAP configuration in the Z600 is to use the step-by-step WAP configurator available on http://www.SonyEricsson.com. The configurator utilizes OTA provisioning.

Manual configuration is done using the menu sys- tem in the phone. This is described in the User’s guide.

Z600 specifications

The Tannoy Z600 is a remarkable loudspeaker that embodies the company’s commitment to high-performance audio, blending classic craftsmanship with innovative technologies. Designed for both professional and home listening environments, the Z600 serves as an exemplary model in Tannoy’s extensive range of audio solutions.

One of the standout features of the Z600 is its dual-concentric driver design. This technology has been a hallmark of Tannoy's engineering for decades, ensuring that sound is emitted from a single point source. This results in an incredibly coherent soundstage with exceptional imaging, allowing listeners to experience audio with a sense of depth and clarity that is often absent in traditional speaker designs.

The Z600 further enhances its audio reproduction capabilities through the use of high-quality drivers. It houses a 6.5-inch bass driver paired with a 1-inch high-frequency driver. The combination enables the speaker to handle a wide frequency range, delivering rich bass tones while maintaining crystal clear highs. The speaker's crossover design is meticulously crafted to ensure seamless integration between the bass and treble drivers, which contributes to a balanced and natural sound signature.

Equipped with a robust MDF cabinet, the Z600 is designed to minimize unwanted resonances and provide a solid base for sound reproduction. The cabinet's architecture is complemented by a stylish finish, available in various veneers, allowing it to blend well with any modern or classic décor.

Installation options are versatile, featuring bi-wiring capabilities that enhance the speaker's performance. This feature allows for separate connections to the bass and treble drivers, optimizing audio quality and enabling advanced customization based on user preference.

Another notable characteristic of the Tannoy Z600 is its wide dispersion pattern. This attribute ensures that sound remains consistent and clear even when listening from different positions in the room. This makes the Z600 an excellent choice for both casual listening and critical monitoring in professional setups.

With its combination of innovative technologies, premium materials, and expert craftsmanship, the Tannoy Z600 stands out as a top-tier choice for audio enthusiasts. Whether for home entertainment or studio monitoring, it offers a listening experience that is both engaging and immersive, making it a worthy addition to any audio system.
