Abstract
A method for transmitting sensed data in a wireless sensor network including multiple sensors, includes: encrypting the sensed data with an encryption key and a verification key to generate encrypted data in each of the multiple sensors that senses data; wirelessly receiving the encrypted data from the multiple sensors; determining that the sensed data from one of the multiple sensors is different from the sensed data from others of the multiple sensors without decrypting the encrypted data; and transmitting the encrypted sensed data determined to be different.
