A security defending method, a coprocessor, and a processing apparatus are disclosed. The security defending method is applicable in a coprocessor, including: receiving a jump destination encryption request for the operation task; using mask configuration to perform first mask processing on the first jump destination address value to obtain a first intermediate jump destination address value; performing an authentication operation based on the first jump destination storage address, a key reference value corresponding to the operation task and the first intermediate jump destination address value, to obtain a first encryption result value; using the mask configuration to perform second mask processing on the first encryption result value to obtain a first intermediate encryption result value; performing an authentication operation on the first intermediate encryption result value and the first jump destination address value to obtain a first encryption jump destination address value.
