   en.wikipedia.org/wiki/PAdES

   Digital signatures are a secure and legally binding means to implement electronic signatures through three cryptographic algorithms: [5] the key generating algorithm that randomly selects a private key and its corresponding public key; the signing algorithm that produces the digital signature from the message and private key

   PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2. PDF files may also contain embedded DRM restrictions that provide further controls that limit copying, editing, or printing. These restrictions depend on the reader software to obey them ...

6. Message authentication - Wikipedia

   en.wikipedia.org/wiki/Message_authentication

   Message authentication is typically achieved by using message authentication codes (MACs), authenticated encryption (AE), or digital signatures. [2] The message authentication code, also known as digital authenticator, is used as an integrity check based on a secret key shared by two parties to authenticate information transmitted between them. [4]

7. BLS digital signature - Wikipedia

   en.wikipedia.org/wiki/BLS_digital_signature

   A BLS digital signature, also known as Boneh–Lynn–Shacham [1] (BLS), is a cryptographic signature scheme which allows a user to verify that a signer is authentic.. The scheme uses a bilinear pairing:, where ,, and are elliptic curve groups of prime order , and a hash function from the message space into .
