PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.

Since then, it has been under the control of an International Organization for Standardization (ISO) committee of ...
The Digital Signature Standard (DSS) is a Federal Information Processing Standard specifying a suite of algorithms that can be used to generate digital signatures established by the U.S. National Institute of Standards and Technology (NIST) in 1994. Five revisions to the initial specification have been released: FIPS 186-1 in 1998, [1] FIPS 186 ...
AES and QES have a higher evidentiary value than simple or ‘standard’ electronic signatures. QES is recognised the same legal value as a handwritten signature. [3] PAdES standards travel in the same direction and have the same aims as digital signatures (AES and QES). This means they can be easily verified in any PDF reader and as [5]
AES3 is a standard for the exchange of digital audio signals between professional audio devices. An AES3 signal can carry two channels of pulse-code-modulated digital audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. [1]
ATSC standards are marked A/x (x is the standard number) and can be downloaded for free from the ATSC's website at ATSC.org. ATSC Standard A/53, which implemented the system developed by the Grand Alliance, was published in 1995; the standard was adopted by the Federal Communications Commission in the United States in 1996. It was revised in 2009.
The Digital Standards Organization (DIGISTAN) states that "an open standard must be aimed at creating unrestricted competition between vendors and unrestricted choice for users." [39] Its brief definition of "open standard" (or "free and open standard") is "a published specification that is immune to vendor capture at all stages in its life ...
