1. A radio secure reader for controlling an operation mode of a radio secure tag, comprising:
- a reader modem to receive the operation mode from the radio secure tag; and
a reader processing unit to identify the received operation mode as a normal mode or a secure mode, and to control the radio secure tag based on the identified operation mode, wherein the control comprises of operating the radio secure tag only in a single mode, either the secure mode or the normal mode, using a toggle mode command unit, and whereinwhen the operation mode is identified as the normal mode, the reader processing unit performs a first inventory process and performs authentication processing with respect to the radio secure tag, and when the authentication processing is completed, the reader processing unit is allowed to control the radio secure tag, andwhen the operation mode is identified as the secure mode, the reader processing unit performs a second inventory process including authentication processing with respect to the radio secure tag and then, is allowed to control the radio secure tag.

6. A radio secure tag for supporting a secure mode and a normal mode, comprising:
-
a tag modem to transmit a predetermined operation mode to a radio secure reader in response to an access request from the radio secure reader; and a tag processing unit to perform authentication processing according to processing in the radio secure reader based on the operation mode, and to operate according to control of the authenticated radio secure reader when the radio secure reader is authenticated, wherein the control comprises of operating the radio secure tag only in a single mode, either the secure mode or the normal mode, using a toggle mode command unit, and wherein; the tag processing unit comprises a normal mode tag processing unit, when the predetermined operation mode corresponds to the normal mode, the normal mode tag processing unit performs a first inventory process and then, as the authentication processing, transmits a first challenge_tag message to the radio secure reader and receives, from the radio secure reader, a second challenge_tag message in which the first challenge_tag message is encrypted and compares the first challenge_tag message with the second challenge_tag message, and the tag processing unit comprises a secure mode tag processing unit, when the predetermined operation mode corresponds to the secure mode, the secure mode tag processing unit performs a second inventory process and then, as the authentication processing, transmits a first random number to the radio secure reader and receives, from the radio secure reader, a second random number in which the first random number is encrypted and compares the first random number with the second random number.
