Abstract Syntax Notation One (ASN.1) is a formal language for abstractly describing messages to be exchanged among an extensive range of applications involving the Internet, intelligent network, cellular phones, ground-to-air communications, electronic commerce, secure electronic services, interactive television, intelligent transportation systems, Voice Over IP and others. Due to its streamlined encoding rules, ASN.1 is also reliable and ideal for wireless broadband and other resource-constrained environments. Its extensibility facilitates communications between newer and older versions of applications. In a world of change, ASN.1 is core technology, constantly adapting to new technologies.

ASN.1 is a critical part of our daily lives; it’s everywhere, but it works so well it’s invisible!
