4. About Digital Signatures
Electronic analog of real-world signatures and stamps
Enabler for paperless business
Establishes connection between signing party and document content

5. Traditional symmetric key cryptography

6. Asymmetric key cryptography Key-pair

7. CRYPTOGRAPHY
Cryptographic hash

8. Public Key Infrastructure
Confirmation of identity
Certificate Authority
Legal authority
Private Key
Digital certificate

9. Signing Process

10. Enables confirmation of existence of content prior given point in time
Digital Time-Stamps
Enables confirmation of existence of content prior given point in time
RFC 3161 standard

11. XML Signature Syntax and Processing http://www.w3.org/TR/xmldsig-core/
Standards - XML
XML Signature Syntax and Processing
XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere

12. XML DSIG Structure <Signature> <SignedInfo>
<Reference>
<DigestMethod />
<DigestValue></DigestValue>
</Reference>
</SignedInfo>
<SignatureValue></SignatureValue>
<KeyInfo></KeyInfo>

13. XML Detached Signature
<DocumentElement>
<Data></Data>
<Signature />
</DocumentElement>

14. XML ENVELOPED Signature
<DocumentElement>
<Data>
<SubData>
<Signature />
</SubData>
</Data>
</DocumentElement>

15. XML ENVELOPING Signature
<SignedInfo />
<SignatureValue />
<KeyInfo />
<Object>
Embeded Object Data
</Object>

16. XML Advanced Electronic Signatures (XADES)
Basic electronic signature (XAdES-BES)
Explicit policy electronic signatures (XAdES-EPES)
Electronic signature with time (XAdES-T)
Electronic signature with complete validation data references (XAdES-C)

17. PDF Digital signatures
