Abstract
Methods and apparatus provide secure two-way (reader-to-tag and tag-to-reader) RFID communications. According to one aspect, a tag receives a noise-encrypted RF carrier signal from a reader and backscatter modulates it with tag information. Eavesdroppers cannot extract the tag information from the backscattered signal because it is masked by the noise encryption.
