ETSI CAdES/PAdES Profile B-B / B-T Specification
Technical explanation of ETSI & ISO 32000 PDF Advanced Electronic Signature (PAdES) Profiles:
1. What is PAdES Baseline Profile B-B?
PAdES Profile B-B (Baseline Basic) ensures that digital signatures embedded in PDF documents are globally recognized by Adobe Reader as valid signatures. It encapsulates the signer’s X.509 certificate, SHA-256 hash digest, and visual signature appearance.
2. What is PAdES Baseline Profile B-T?
PAdES Profile B-T (Baseline Time) incorporates a cryptographically secure RFC 3161 Time-Stamp Authority (TSA) token into the signature structure. This proves non-repudiably the exact date and timestamp when the signature was applied.
PKCS#7 Digital Signatures & Byte-Range Cryptography
Cryptographic structure of PKCS#7 signed data objects and PDF Byte-Range verification:
1. What is PKCS#7 / CMS Architecture?
PKCS#7 (Public Key Cryptography Standard #7) is an international cryptographic standard for signed data encapsulation. When signing a PDF in ViViD eSigner, a PKCS#7 SignedData blob is constructed using RSA/ECDSA keys and embedded into the PDF’s internal `/ByteRange` array.
2. Tamper-Evident Byte-Range Integrity
If anyone alters even 1 byte or character of the PDF after signature placement, Adobe Reader and our online verification portal immediately detect hash mismatch and display a tamper warning.
Global Statutory Frameworks & Legal Acts
