Digital Signature Components

A digital signature has the following components:

An element (a cell) stored in the file .
Special linkage containing
  • Hash of model or file and optionally its references
  • Signer's certificate
  • Time of signing
  • Optional information, such as expiration, annotation data, signature graphics, or list of prerequisite signatures
"Signature cells" A signature cell is really just a cell. It is created and managed as a normal cell in a cell library. It is then placed in the model that is being signed. What makes a signature cell special is that it itself is digitally signed
