Efficient Attributes

Posted in Publications tagged , , , at 16:55 by Thomas Groß

Considering the use of anonymous credentials for government issued identities, one finds that the number of attributes certified is quite large. The original scheme,  however, would loose efficiency with the number of attributes becoming larger. Also, consider the case of a certificate stating the date of birth. If one now would want to prove that one is between 12 and 16 years old, the known method to do so is not practical on computationally challenged devices such as smart cards which would be the target platform for electronic identity cards.
