2. An authentication system for transmitting information, said authentication system storing identification information of a plurality of providing users and a plurality of receiving users and being adapted to
receive information from at least one of said providing users; -
authenticate said at least one providing user; transmit a message including said information via a mobile communications network to a receiving user'"'"'s mobile terminal; receive an acknowledgement message or a response message from said receiving user; and transmit a confirmation message to said one providing user based upon said acknowledgement or response message; wherein said confirmation message requires an acknowledgement message from said one providing user and said authentication system further being adapted to send a confirmation message to said receiver user'"'"'s terminal, notifying the terminal to decrypt and display the decrypted part of said message.

3. A method of transmitting a message via a mobile telecommunications network from a sender'"'"'s device to a user'"'"'s terminal,
wherein the user is required to acknowledge receipt of said message in a predetermined way and an acknowledgement message is subsequently transmitted to the sender of said message; -
wherein at least a portion of the text message is encrypted by the sender'"'"'s device before transmission and decrypted by the receiving terminal before display; wherein the text message comprises a first portion including the body of said message and a second portion containing encryption data used for encryption of said body and required for decryption of data included in said body; and wherein authentication data provided by the receiving user and/or response data to said message are encrypted using said encryption data.

4. A method of transmitting a message via a mobile telecommunications network from a sender'"'"'s device to a user'"'"'s terminal,
wherein the user is required to acknowledge receipt of said message in a predetermined way and an acknowledgement message is subsequently transmitted to the sender of said message; -
wherein in said sender'"'"'s device and in said receiving user'"'"'s terminal a transaction reference counter is implemented and wherein each of said transaction reference counters is incremented if a message is successfully received; and wherein a transaction reference is included in every message transmitter from the receiving user to the sender. - View Dependent Claims (5)

6. An authentication system for transmitting information, said authentication system storing identification information of a plurality of providing users and a plurality of receiving users and being adapted to
receive information from at least one of said providing users; -
authenticate said at least one providing user; and transmit a message including said information via a mobile communications network to a receiving user'"'"'s mobile terminal; further being adapted to extract a public key specific to said receiving user from said stored identification infonnation and to use said further public key for encryption of said at least part of said message; provide a communication specific public/private key pair valid only for a single communication between the authentication system and said receiving user, provide a communication specific public/private key pair valid only for a single communication between the authentication system and said receiving user, wherein said communication comprises a message and a response to said message; encrypt at least part of said message using said communication specific public/private key pair; and
tosend said communication specific public key to said receiving user as part of said message. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 54, 55, 56, 57, 58, 59)

36. A method of transmitting a message via a mobile telecommunications network from a sender'"'"'s device to a user'"'"'s terminal, wherein
the user is required to acknowledge receipt of said message in a predetermined way; -
an acknowledgement message is subsequently transmitted to the sender of said message; said user is required to authenticate himself by providing authentication data; and
a central authentication system verifies the user'"'"'s authentication; and
whereinat least a portion of the text message is encrypted by the sender'"'"'s device before transmission and decrypted by the receiving terminal before display, the text message comprising a first portion including the body of said message and a second portion containing encryption data used for encryption of said body and required for decryption of data included in said body; and wherein said authentication data provided by the receiving user and/or response data to said message are encrypted using said encryption data. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
