The first is given in confidence by the service provider to terminal manufacturers with whom they have a commercial relationship; the second is broadcast in the &#034;Encryption Administration Group,&#034; which is also a type 8A group. This specification explains the purpose of the two keys and how often and when the transmitted key may be changed.<\/p>\n<p>Before an individual terminal may present decrypted messages to the end-user, it must have been activated to do so. Activation requires that a PIN code be entered. The PIN code controls access rights to each service and subscription period, allowing both lifetime and term business models to co-exist.<\/p>\n<p>The specification also describes the considerations for service providers wishing to introduce an encrypted RDS-TMC service, migrating from either a &#034;free-to-air&#034; service based on public &#034;Location Tables&#034; or a commercial service based on a proprietary Location Table.<\/p>\n<p>Finally, &#034;hooks&#034; have been left in the bit allocation of the type 8A group to allow extension of encryption to other RDS-TMC services.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Traffic and Traveller Information (TTI) \u2014 TTI messages via traffic message coding \u2014 Part 6: Encryption and conditional access for the Radio Data System \u2014 Traffic Message Channel ALERT C coding<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2006-04<\/td>\n<td>26<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":593527,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[108,698,2634],"product_tag":[],"class_list":{"0":"post-593513","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-03-220-20","7":"product_cat-35-240-60","8":"product_cat-iso","10":"first","11":"instock","12":"sold-individually","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/593513","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/593527"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=593513"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=593513"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=593513"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
