Abstract: In order to provide the communication services to a user equipment comprising or applying secure edge protection proxy authentication: in a first step, a network function of a visited telecommunications network receives a request related to the user equipment, triggering a message towards a third secure edge protection proxy entity or functionality; and in a second step, the third secure edge protection proxy entity or functionality accesses a first secure edge protection proxy entity or functionality in an authenticated manner such that a message related to a second network identifier information is able to be sent, by the visited telecommunications network, to a network function in a first telecommunications network and accepted by the first telecommunications network.

Abstract: An external storage medium adapter for establishing a connection between a computer and an external storage medium, said external storage medium adapter comprising: an first interface for connecting to said computer and for receiving through said interface from said computer data which is to be stored in encrypted form on a separate persistent storage device; an interface for connecting said external storage medium adapter to said separate persistent storage device; an encryption engine for encrypting data which is received from said computer and which is to be written in encrypted form onto said persistent storage device by using one or more credentials; a credential storage for storing said one or more credentials used to encrypt said data.

Abstract: An external storage medium which can be connected to a computer and onto which user data can be written by a user of said computer, that medium comprising: a storage unit for storing therein said user data; a storage unit for storing therein an expiration condition; a counter and/or a timer for incrementally measuring a time value and/or a number of events; a connectivity detection unit for detecting whether said external storage unit is connected to said computer or not; a control module for if said connectivity detection unit detects that said external storage medium has been detached from said computer, triggering said counter or said timer to start to operate, said control module being adapted to compare the value of said measured time and/or said measured number of events with said expiration condition, whereas if said control unit determines that said value of said measured time and/or said measured number of events coincides with said expiration condition said control unit carries out a processing such
