Abstract: A mobile app is in a form of a package file. A structural feature digest is generated from contents of a manifest part, bytecode part, and resource part of the package file. A mobile device receives an unknown mobile app, generates a structural feature digest of the unknown mobile app, and sends the structural feature digests to a backend system over a computer network. In the backend system, the structural feature digest of the unknown mobile app is compared to structural feature digests of known malicious mobile apps. The unknown mobile app is detected to be malicious when its structural feature digest is similar to that of a known malicious mobile app.

Abstract: Taint is dynamically tracked on a mobile device. Taint virtual instructions are added to virtual instructions of a control-flow graph (CFG). A taint virtual instruction has a taint operand that corresponds to an operand of a virtual instruction and has a taint output that corresponds to an output of the virtual instruction in a block of the CFG. Registers are allocated for the taint virtual instruction and the virtual instructions. After register allocation, the taint virtual instruction and the virtual instructions are converted to native code, which is executed to track taint on the mobile device.

Abstract: The present disclosure provides an electrostatic chuck (ESC) and a method for manufacturing the plurality of protrusions of the ESC. The electrostatic chuck includes a support surface for carrying a workpiece and the plurality of protrusions distributed at intervals on the support surface. The protrusions are formed by a hydrogen-free amorphous carbon with a resistivity ranging from 10?4 ?·cm˜109?·cm. For the ESC provided by the present disclosure, the protrusions are formed by the hydrogen-free amorphous carbon and have a high hardness and a good wear resistance, which may effectively prevent a generation of particles. As such, the negative impact of the particles on the semiconductor process may be avoided, and the hydrogen does not dissociate in a high-temperature environment. Thereby, a problem that the protrusions may easily fall off and may not be suitable in the high-temperature environment (above 250° C.) may be solved.
