Abstract: 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.

Abstract: The invention relates to method and system for a secure PKI (Public Key Infrastructure) key registration process in a WPKI (Wireless PKI) environment comprising a registration server and client provided with a key pair. Especially the invention relates to a registration method, where a registration request for a public key of the key pair is formed using second and only part of the first information provided to a client in separated communication connections. The formed registration request comprising the public key is then provided with a verifying code determined over the request to the registration server in order to register the public key.

Abstract: 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.

Abstract: 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.

Abstract: A method and system for the transmission of payment messages in a telecommunication system that includes a smart card, a payment application on the smart card, a telecommunication connection and a payment server disposed in a telecommunication network and connected to the payment application. In the inventive method, a smart card client is disposed on the smart card, the payment application is connected to the smart card client, a smart card server is provided in the telecommunication network and is connected to the payment server, and the smart card client is connected to the smart card server via the telecommunication connection. The inventive system includes a smart card client disposed on the smart card and connected to the payment application, and a smart card server disposed in the telecommunication network and connected both to the payment server and, via the telecommunication connection, to the smart card client.

Abstract: A method for sending information from a server (S) to a mobile station (MS) which comprises a mobile equipment (ME) and a Subscriber Identity Module, or SIM. The mobile equipment (ME) communicates with the network (RAN) by a first protocol which supports sending an arbitrarily long data stream. The server (S) sends a first data stream (1a) via the network (RAN) to the mobile equipment (ME) using the first protocol. The mobile equipment (ME) uses the first data stream (1a) for generating a second data stream (2) and sends the second data stream (2) to the SIM by emulating reception of one or more connectionless messages. Alternatively, the mobile equipment (ME) may generate or receive locally the information (1b) to be sent to the SIM.
