Digital signature standard is a collection of programs and standards developed by GJ Security Bureau in the United States, which is used to generate digital signatures for verifying electronic documents.

The so-called digital signature is a function of signing in the form of digital communication, with the purpose of proving the identities of both parties and ensuring the security of communication. This is a cryptographic system.

Digital signature standards ensure that digital signatures can be authenticated and electronic documents carrying digital signatures are secure. The standard also ensures the non-repudiation of signatures and provides all protection measures against counterfeiting.

In 1994, the digital signature standard was designated as the federal information processing standard by the American GJ Institute of Standards and Technology, and became the standard for the American government to authenticate electronic documents.
