Abstract. We present a rigorous dynamical relation for aging phenomena - the aging relation - for Ising spin glasses using the method of gauge transformation. The waiting-time dependence of the autocorrelation function in the zero-field-cooling process is equivalent to that in the field-quenching process. There is no aging on the Nishimori line; this provides arguments for dynamical properties of the Griffiths phase and the mixed phase. The present method can be applied to other complex systems with gauge symmetry such as the XY gauge glass.
