Original Press Release:

Valimo Introduces Dedicated Mobile Signature Client for SIM Cards

HELSINKI, Finland, January 24/- Valimo Wireless has achieved what the telecom industry has been looking for: a generic, easy-to-use, secure and feature-rich mobile signature client. With this client application, located on a SIM card, mobile phone users can authenticate their identity, as well as approve and digitally sign content.

"The Valimo Mobile Authentication Client (VMAC) enables mobile network operators to offer advanced Wireless PKI services with greater functionality," comments Petteri Heinonen, Director of Product Management at Valimo.

The VMAC adds significant value for mobile network operators and SIM vendors because it:

o Is specifically designed for mobile signatures and strong mobile authentication
o Uses state-of-the-art security features, which are already accepted by the industry
o Deploys quickly and easily as a standard SIM card profile element from SIM vendors
o Works with server side systems compliant with the ETSI standard for Mobile Signature Services (MSS)

The VMAC and Valimo's other mobile signature applications have been fine-tuned through extensive feedback from Valimo customers and mobile network operators.

Key VMAC features include:

o 'See-what-you-sign' module
o Capability to sign large documents
o Local PIN and PUK management for the signing application
o Support for multiple hash algorithms, as well as different digital key sizes and multiple key pairs
o On-board digital key generation
o Encrypted communications between the SIM card and the destination system (i.e. Acquiring MSS-system)

Since the VMAC is SIM, OTA- and mobile signature system- vendor independent, mobile network operators can now acquire mobile signature-enabled SIM cards from a variety of sources.
