Patent number: 9582053Abstract: A memory erasing method and apparatus for erasing important data of a nonvolatile memory within the apparatus to prevent illegal access using attitude information measured in an inertial measurement sensor and a low power microprocessor regardless of the power supply state of the apparatus. The apparatus includes a power switching circuit unit for selecting one from among an external power source and a battery. An inertial measurement sensor measures attitude information of the memory erasing apparatus, using power supplied from the external power source or the battery. A low power microprocessor erases important data from a memory device in a first manner using power from the external power source, and in a second manner using power from the battery, the first manner being different from the second manner.Type: GrantFiled: December 5, 2014Date of Patent: February 28, 2017Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Dae Seon Park, Bon Seok Koo, Jung Hyung Park, Jin Ha Hwang

Patent number: 9032005Abstract: A random number generation method and apparatus using a low-power microprocessor is provided. In the random number generation method, a low-power microprocessor determines whether external power is supplied to a random number generator. The low-power microprocessor updates an internal state of the random number generator based on a first scheme if it is determined that the external power is supplied to the random number generator. The low-power microprocessor updates the internal state of the random number generator based on a second scheme different from the first scheme if it is determined that the external power is not supplied to the random number generator.Type: GrantFiled: May 17, 2013Date of Patent: May 12, 2015Assignee: Electronics and Telecommunications Research InstituteInventors: Dae-Seon Park, In-Seok Kang, Byeong-Ho Ahn
