Abstract: An apparatus and method for creating a finite blockchain is provided. The blockchain comprises a genesis block that is the first block of the blockchain. The genesis block comprising a genesis expiry time. The method comprises the steps of creating a reincarnation block when a predefined condition is satisfied and appending it to the blockchain; determining whether the genesis expiry time has elapsed based on an expiry period; if the genesis expiry time has elapsed then identifying a first reincarnation block; if the first reincarnation block is identified then deleting all the blocks preceding the first reincarnation block including the genesis block in the block chain.

Abstract: The disclosure relates to a method (30) of handling a hash-tree based data signature. The method (30) is performed in a first device (13, 13a) and comprises: receiving (31), from a second device (12, 12a, 12b), a data signature generation request, the request comprising an indication on type of storage of a generated data signature; generating (32), in response to the data signature generation request, the data signature B using a hash-tree based data signing method; and providing (33), to the second device (12, 12a, 12b), a reference C to the generated data signature, wherein the generated data signature is obtainable by means of the reference C. The disclosure also relates to a method in a second device, corresponding devices, computer programs and computer program products.

Abstract: There is provided mechanisms for handling transfer of a data object between network domains. A method is performed by a first data controller of a first network domain. The method comprises obtaining a request for transmission of the data object to a second data controller of a second network domain. The method comprises obtaining an identifier identifying allowable transfer of the data object between the first network domain and the second network domain. The method comprises providing a cryptographic integrity signature to the data object. The method comprises enabling transfer of the data object to the second network domain according to the identifier.

Abstract: A method and devices are provided for communicating configuration management notifications from a network element to a network manager in a packet-switched network. The configuration information of the network element is stored at different time instants having a time interval therebetween. Two sets of configuration information are compared in order to determine changes between the two time instants. The changes are then transmitted to the network manager through a communication connection by using a file-based configuration protocol.

Abstract: A method of reallocating charges relating to one or more connections from a first subscriber 1 of a mobile telecommunications network 1 to a second subscriber 2 of that or a different mobile telecommunications network. The method comprises temporarily linking the accounts of the two subscribers maintained in the or each associated Cost Control Node 9,16, receiving at the Cost control Node 9,16 associated with the first subscriber, real time charging messages according to the CAMEL protocol, and allocating the charging messages to the account of the second subscriber including, if necessary, transferring the charging messages to the Cost control Node 17 associated with the second subscriber.

Abstract: The present invention describes a communications network based method for providing a communications network subscriber using SIP signalling for communication path set up with an anonymous temporary identity and a dual anonymous communication system. In the solution according to the present invention a subscriber can reserve a temporary subscriber identity or even several temporary subscriber identities. The temporary subscriber identity will be associated to the person's real phone number in the application server that handles dual anonymous communication in the communications network.
