Abstract:
1. A method for enabling a user to communicate on a virtual private network through a public communication network, a possibility of communicating on said virtual private network depending on an availability to said user of at least one enabling credential sent to the user in encrypted form, comprising the steps of: providing said user with a SIM type module bearing an encryption mechanism; providing the user with a user terminal communicating with the SIM type module; generating the at least one enabling credential; encrypting the at least one enabling credential using information associated with the encryption mechanism borne by the SIM type module; transmitting to the user terminal an encrypted message containing the encrypted at least one enabling credential, wherein the encrypted at least one enabling credential is decrypted at the user terminal based on information generated by the SIM type module using the same encryption mechanism, providing encrypted communication modes between said virtual private network and the user who communicates thereon; providing at least one gateway associated with said virtual private network to activate said encrypted communication modes; registering said at least one gateway and the user with an inter working function; and activating said virtual private network between said user and said at least one gateway; wherein said step of registering said at least one gateway and the user with said inter working function entails the step of identifying which ones, in a set of SIM type modules issued, are SIM type modules enabled to communicate on said virtual private network in relation to a specific gateway.
