A touch substrate includes a first layer wiring group and a second layer wiring group that are located in a peripheral region. The first layer wiring group includes a plurality of first wirings, the second layer wiring group includes a plurality of second wirings, and a square resistance of a first wiring is greater than a square resistance of a second wiring. The peripheral region includes a first wiring region provided with at least one first-type touch lead therein and a second wiring region provided with at least one second-type touch lead therein. Each first-type touch lead includes a first wiring and a second wiring that are connected to each other and whose orthographic projections on the touch substrate are overlapped. Each second-type touch lead includes a second wiring or a first wiring. A length of the first-type touch lead is greater than a length of the second-type touch lead.

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.
