Introduction

GB/T 31308 is a standard that ensures the interoperability of long-term signatures and enables long-term verification of electronic signatures: For the e-commerce market Field security plays a major role: GB/T 31308 is planned to consist of 4 parts:

---Part 1: Long-term signature specification for CMS Advanced Electronic Signature (CAdES): The purpose is to clarify CMS advanced electronic signatures (CAdES) long-term signature specification ensures that this type of electronic signature can be verified for a long time:

---Part 2: Long-term signature specification for XML Advanced Electronic Signature (XAdES): The purpose is to clarify XML advanced electronic signatures (XAdES) long-term signature specification ensures that this type of electronic signature can be verified for a long time:

---Part 3: Long-lasting signature specifications for PDF Advanced Electronic Signature (PAdES): The purpose is to clarify PDF advanced electronic signatures (PAdES) long-term signature specification ensures that this type of electronic signature can be verified for a long time:

---Part 4: Attributes of the certificate object used in the long-lasting signature format: The purpose is to clarify the attributes of the certificate objects required for long-term signature verification:

Specific specifications to ensure that electronic signatures can be verified over the long term:

GB/T 31308 (all parts) adopts ISO 14533 (all parts) in one-to-one correspondence to ensure the long-term verification of electronic signatures:

Implementation standards are in line with international standards: By formulating this series of standards, the relevant standard system will be improved:

Data elements, processes and documents in administration, business and industry Long-lasting signatures Part 4: Format for long-lasting signatures Certificate object properties

1 Scope

This document specifies the PoE (Proofofexistence) attributes and objects used in the long-term signature format, and describes the basic concept of PoE:

Concepts and attribute characteristics are given, and the types, basic fields, and related examples of PoE objects are given:

This document applies to (external) certificate objects used in long-lasting signature formats, i.e. through existing available digital signatures and trusted times:

The value implements dynamic verification of long-lasting signatures:
