'''Conditional access''' (abbreviated '''CA''') or '''conditional access system''' (abbreviated '''CAS''') is the protection of content by requiring certain criteria to be met before granting access to the content. The term is commonly used in relation to [[digital television]] systems and to [[software]].

== In Softwaresoftware ==

Conditional Accessaccess is a function that lets you manage people’s access to the software in question, such as email, applications, documents and information. It is usually offered as [[Software as a service|SaaS]] (Software-as-a-Service) and deployed in organizations to keep company [[data]] safe. By setting conditions on the access to this data, the organization has more control over who accesses the data and where and in what way the information is accessed.

Possible conditions could be:

* [[Operating system|Operating System (OS)]]

When setting up Conditionalconditional Accessaccess, access can be limited to or prevented from the chosen conditions. This way it can be determined that, for example, access is only possible from certain networks or prevented from certain browsers.

Current providers of Conditionalconditional Accessaccess include:

* [[Microsoft]] (including [[Office 365]])

==In the Digital Video Broadcasting==

Under the [[Digital Video Broadcasting]] (DVB) standard, conditional access system (CAS) standards are defined in the specification documents for DVB-CA (conditional access), [[Common Scrambling Algorithm|DVB-CSA]] (the common [[Scrambler|scrambling]] algorithm) and [[DVB-CI]] (the [[Common Interface]]). These standards define a method by which one can obfuscate a digital-television stream, with access provided only to those with valid decryption [[smart cards|smart-cards]]. The DVB specifications for conditional access are available from the [https://web.archive.org/web/20130116162443/http://www.dvb.org/technology/standards/index.xml#conditional standards page on the DVB website].
