A design of e-ID authentication protocol in Gen2 environment

In Gen2 standard basis, hash function, symmetrical algorithm and the like are not supported. As security vulnerability between vertical sections, cloning, wiretapping, middleware and service refusal attacks are possible due to absence of mutual authentication mechanism between tag-readers. Through mutual authentication mechanism between tag and reader, and multiple reader management technique, efficiency in multiple reader management is provided. Hereby, security is enhanced by effectively protecting from clone, wiretapping and middleware attack of tag, which can be used as e-id.
