Patent number: 10505971Abstract: Disclosed approaches for protecting against attacks on a network device, a second network device receives a first message from a first network device. In response to the first message, the second network device determines a first area from which the first network device issued the message. The second network device determines whether or not the first area intersects a second area having the second network device. In response to determining that the first area intersects the second area, the second network device acknowledges the first message to the first network device. In response to determining that the first area does not intersect the second area, the second network device rejects the first message.Type: GrantFiled: November 7, 2016Date of Patent: December 10, 2019Assignee: XILINX, INC.Inventor: Stephen M.

Patent number: 10325646Abstract: The disclosure describes approaches for generating a physically unclonable function (PUF) value. Power is applied to a power control circuit, an SRAM, and a PUF control circuit. After initially powering-up the SRAM, the PUF control circuit signals the power control circuit to disable power to the SRAM. The power control circuit disables power to the SRAM, and then re-enables power to the SRAM after having power to the SRAM disabled for a waiting period. The PUF control circuit reads a PUF value from the SRAM by the PUF control circuit after the enabling of power.Type: GrantFiled: September 15, 2015Date of Patent: June 18, 2019Assignee: XILINX, INC.Inventor: Stephen M.
