METHOD FOR QUICK AND SECURE TRANSMISSION OF ENCRYPTION KEY

摘要

A method for encoding a connection between a base (2) and a mobile part (1), and a computer program product is povided. The method comprises generating a key agreed to by the base (2) and the mobile part (1) during a first connection, wherein the key comprises an index assigned by the base during the first connection, and b) using the generated key for a second connection between the base (2) and the mobile part (1), wherein the data to be transferred between the base (2) and the mobile part (1) are identified and encoded using the index assigned to the key. The security of wireless data transfer is thus increased in a simple and low-cost manner.
