A method for delegating access rights to a secured object includes generating a first-order data packet in a trusted central management device. The data packet contains a first identifier, a first data set having access rights to a secured device and a first data secret key for encryption and signature. A second-order data packet is signed via the first data secret key and is created in the first mobile communication device and contains a unique identifier, reference data, a second data set having access rights, a second data secret key for encryption and a first data container. The first data container is encrypted via the first data secret key and contains the first identifier and the second data secret key. The signed second-order data packet is transmitted to a second mobile communication device of a second user.
