The New Hampshire Declaration Regarding Electronic Filing (HDF) is a legal document that outlines the requirements for the filing of documents and forms electronically with the state of New Hampshire. It establishes the standards for electronic filing and outlines the processes and procedures for creating, submitting, and processing electronic documents. The HDF also establishes the security requirements for the electronic filing system, such as encryption, authentication, and data integrity. There are two main types of Nodes: Standard Nodes and Enhanced Nodes. Standard Nodes provide basic security requirements, while Enhanced Nodes provide additional security measures such as multi-factor authentication, digital signatures, and encryption. Both types of Nodes must be signed by the filer before the electronic filing system will be accepted.
