Abstract: An authentication method is used in pairing a peripheral device to a companion device. The peripheral device sends a first identifier and a first value of a first counter to the companion device. The companion device verifies whether a pairing table stored in the companion device contains the first identifier. When the pairing table does not include the first identifier the companion device initiates a pairing session. When the pairing table includes the first identifier, the companion device compares the first value to a second value associated with the first identifier in the pairing table. In response to the first value being greater than the second value, the companion devices initiates a nominal session and in response to the first value being lower than or equal to the second value, execution of the method is stopped.
