摘要： A parallel processing shrinking key generator is provided. The parallel processing shrinking key generator includes: a selection linear feedback shift register (LFSR); a source LFSR; a selection logic circuit for selecting one of a source bit of the source LFSR and a predetermined input bit according to a selection bit of the selection LFSR; an index counter for assigning an index where output bits of the selection logic circuit are stored at a next clocking of a clock signal; and an output amount register for shifting an output bit of the selection logic circuit according to the assignment of the index counter.

摘要： A tamper detection method and a data storage device using the same are provided. The tamper detection method includes sensing a value of pressure applied to a data storage device using a pressure sensor, comparing the sensed pressure value with an initial pressure value sensed at an initial operation time of the data storage device, and detecting malicious tamper by comparing a threshold pressure value varying with the number of loads applied to the data storage device when the sensed pressure value is smaller than the initial pressure value.
