A new copyright protection scheme using the multiple RSA cryptosystems in personal cards for network shopping

摘要

A major problem in circulating copyrighted digital content through a computer network is how to protect against the illegal copying of the content. As a means of addressing this problem, we propose a new copyright protection scheme which features the use of a personal card (e.g. PCMCIA Card, PC Card) and the dividing between various parties of a customer's card private key for a RSA public key cryptosystems (Rivest, 1978). Our proposed scheme has many advantages in key management.
