Method for creating a virtual private network using a public network ". The objective of the present invention involves exchange of data between several computers or multimedia units through a public network while ensuring the confidentiality of the data.The aim is achieved by a method for creation and use of a virtual private network (VPN), which has a plurality of units connected to a public network, each unit having means of security that has a unique number ua1, this method being characterized by the fact that understand the years Es stages: - generate a right DN associated with the unique number uan.By means of safety of a unit a; - to transfer the right of DN to the middle of security at least one unit a; - encrypt data sent by the unit Bu and the descriptografau00e7u00e3o of DN by a key data criptografau00e7u00e3o KS; - to receive the encrypted data by The second unit a,Present these data to the means of safety of unit a check if the right DN is present, and if that is the case, to decrypt the data with the key data of criptografau00e7u00e3o KS.
