摘要:
A method of encrypting data is provided. The method includes dividing data in packet units into N data blocks; generating an initial counter value using a random number used for generating an encryption key for encrypting the data blocks; generating N counter values by increasing the initial value by a predetermined value N times and encrypting the N counter values using the encryption key; and performing an exclusive OR operation on the N encrypted counter values and the N data blocks.
