1. A tag authentication method, comprising:
- generating a first random number and transmitting the first random number to a tag by a reader;
receiving a second random number and a first verification value from the tag by the reader;
computing a second verification value based on the first random number and the second random number by the reader; and
comparing the first verification value and the second verification value by the reader.

Abstract
A tag authentication method, and a tag and reader performing the method are provided. The tag authentication method, including: a reader generating a first random number and transmitting the first random number to a tag; the reader receiving a second random number and a first verification value from the tag; the reader computing a second verification value based on the first random number and the second random number; and the reader comparing the first verification value and the second verification value.
