METHOD AND APPARATUS TO PROVIDE AUTHENTICATION AND CONFIDENTIALITY OF LOW COMPLEXITY DEVICES

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus to provide a cryptographic protocol for secure authentication, confidentiality, and anonymity.SOLUTION: A method comprises: authentication based on a use of a private key of a low processing power system; confidentiality to protect a tag identifier so that an unauthorized party cannot learn the tag identifier; and untraceability to ensure that a different value is returned in response to a challenge so that a reader cannot identify the low processing power system by the response.
