Abstract: Disclosed herein is a method performed by an apparatus. In the method, a payload information item is obtained that is to be communicated to at least one recipient. An encrypted payload information item is obtained by encrypting said payload information item such that it is decryptable by use of a first decryption key and a second decryption key. Further, a message containing said encrypted payload information item is sent or triggered to be sent to said recipient.

Abstract: Disclosed herein are embodiments of a method performed by an apparatus. In the method, a message including a plurality of encrypted payload information items is generated. Each of the plurality of encrypted payload information items is decryptable with a respective decryption key of a plurality of decryption keys. The message is to at least one recipient.

Abstract: A method is disclosed in which an authentication request is received related to authentication of a user of an electronic device towards a server of a service provider. Integrity of the electronic device and/or of an integrity of at least one application of the electronic device is checked. Authentication of the user of the electronic device is performed. Authentication information is returned towards the server of the service provider. A part of the authentication information is indicative of the user having been authenticated by the authentication, and a part of the authentication information represents that the electronic device and/or the at least one application has/have been considered integer by the checking. Further methods and related apparatuses, computer programs and a system are disclosed.
