The invention claimed is: 1. A method of controlling the functioning of a portable medicament dispenser, said portable medicament dispenser being for use with a refill container which is insertable in said medicament dispenser in order to perform dispensing of medicament from said refill container, said method comprising: (a) providing a memory for storing one or more parameters relating to the functioning of said dispenser; (b) storing authentication data for authenticating data for controlling a function of said dispenser; (c) receiving control data for said dispenser; (d) performing authentication of the control data using said stored authentication data; (e) in dependence on a result of the authentication, activating one or more parameters in said memory to control functioning of said dispenser in accordance with said control data, wherein step (c) comprises receiving said control data in a refill container; and step (d) comprises performing authentication of the control data in said refill container, and in that following said authentication, said control data is stored on said refill container, such that said control data can be transferred to said memory following insertion of said refill container into said dispenser. 2. A method according to claim 1, wherein the step of authentication comprises checking a code accompanying the control data. 3. A method according to claim 2, wherein said authentication data comprises an encryption key whereby said code is checked. 4. A method according to claim 2, wherein said code comprises a digital signature formed by digital signature generation from said control data. 5. A method according to claim 1, wherein the step of authentication comprises decryption of said control data. 6. A method according to claim 5, wherein said authentication data comprises an encryption key whereby said control data is decrypted. 7. A method according to claim 6, wherein said encryption key used for decryption of said control data is a shared secret key. 8. A method according to claim 1, wherein the authentication comprises a cryptographic challenge/response procedure. 9. A method according to claim 1, wherein said step of authentication further comprises performing authentication in said portable medicament dispenser. 10. A method according to claim 1, wherein said portable medicament container is for use with a docking station, and wherein said step of authentication further comprises performing authentication in said docking station for said dispenser. 11. A method according to claim 1, wherein said portable medicament dispenser is for use with a node of a data communications network, and wherein said control data comprises control data received from said network node. 12. A method according to claim 1, wherein said control data comprises data arranged to control a dose count function of said dispenser. 13. A method according to claim 1, wherein said control data comprises data arranged to control a reminder function of said dispenser. 14. A method according to claim 1, wherein said control data comprises data arranged to control a dosage amount during a dispensing operation. 15. A portable medicament dispenser, said portable medicament dispenser comprising a refill container which is insertable in said medicament dispenser in order to perform dispensing from said refill container, said dispenser comprising: (a) a memory for storing one or more parameters relating to the functioning of said dispenser; (b) means for storing authentication data for authenticating data for controlling a function of said dispenser; (c) means for receiving control data for said dispenser; (d) means for performing authentication of the control data using said stored authentication data; (e) means for, in dependence on a result of the authentication, activating one or more parameters in said memory to control functioning of said dispenser in accordance with said control data, wherein said means (c) comprises means for receiving said control data in said refill container; and said means (d) comprises means for performing authentication of the control data in said refill container; and in that said refill container is adapted to store said control data following said authentication, such that said control data can be transferred to said memory following insertion of said refill container into said dispenser. 16. A portable medicament dispenser according to claim 15, wherein said means (d) comprises means for checking a code accompanying the control data. 17.
