Applying a modified elliptic curve signatureequation, we gel a more efficient signature scheme than the existing ECDSA (elliptic curve digitalsignature algorithm) from the computability and security view. Our scheme has a shorter key, fastercomputation, and better security.展开更多

The objective of this standard is to maximize content focused multimedia applications. In order to provide full interoperability and flexibility, we use the eXtensible Markup Language( XML ) to express the self describing scheme. We will demonstrate the flexibility and efficiency of our self describing scheme.展开更多
