Abstract: A method for generating a random number comprises selecting a group of at least two servers within a network; receiving a server specific string from at least two servers of the group; and using the server specific strings to generate the random number.

Abstract: A method to validate ownership of a resource within a network, comprising selecting a group of at least two validation agents such that network routes between a validation agent of the group and entities of a group of one or more entities associated to the resource do not intersect. The method further comprises transmitting a property of the resource to be validated and an address indicator for the resource from a coordinating agent to the group of validation agents. Also, the method comprises querying the property of the resource from the entities using the validation agents of the group to determine queried properties; and evaluating the queried properties to validate ownership of the resource.

Abstract: Examples relate to a method, an apparatus and a computer program for processing a plurality of electronic messages, and to an electronic message server. The method comprises obtaining (110) the plurality of electronic messages. The method further comprises selecting (120) at least a subset of electronic messages of the plurality of electronic messages based on information related to a plurality of suspicious electronic message sender identifiers. The method further comprises determining (130), whether a number of electronic messages of the subset of electronic messages obtained within a pre-defined time interval exceeds a threshold. The method further comprises discarding (140) the electronic messages of the subset of electronic messages if the number of electronic messages of the subset of electronic messages obtained within the pre-defined time interval exceeds the threshold.
