The paper presents the possibility of analyzing the electromagnetic field as a constrained dynamical system. The transversality of the electromagnetic waves leads to difficulties in their covariant description. The longitudinal and the temporal components appear as non- physical degrees of freedom. In order to develop a canonical formalism it is necessary to use a phase space extended with ghost type generators. In this space the gauge symmetry of the field can be replaced by a global BRST symmetry. Our construction will correspond to a generalized symmetry that can be split in many pieces. This decomposition could be very useful in the description of multi-interaction processes.
