The invention relates to method and system for using PKCS and especially PKCS#10 registration standard on a mobile environment and in particularly in a WPKI (Wireless PKI) environment comprising a registration server and a client provided with a key pair is provided only with a part of the certificate request info defined on the PKCS registration standard. A PKCS registration structure is formed by the client of said part of the certificate request info and the public key to be registered, after which a verifying code is determined using at least part of said formed PKCS registration structure. Finally said verifying code and the public key are delivered to the registration server advantageously without delivering said part of the certificate request info received at first by the client.

Methods and systems for using PKCS registration on mobile environment

A method and system for encrypting, in a telecommunication system, outgoing message traffic between mobile stations operating in accordance with current mobile communication standards and/or between a mobile station and a service provider, and for decrypting incoming message traffic, includes directing encrypted messages to and receiving encrypted messages from only those members of a limited closed receiver group that are located in a given geographic area.

Method and system for the processing of messages in a telecommunication system

The present invention provides, for use in telecommunication systems, a system and method enabling implementation of dynamic memory management in a subscriber identity module via an application or management system stored in the subscriber identity module. The memory regions in the subscriber identity module can be dynamically allocated to store or accommodate customers' and service providers' own applications, and the amount of information that the system operator need to store relating to the memory structures of and stored applications in subscriber identity modules that it owns or controls is significantly reduced.
