Redirection Parameter Signing
External Web Server (EWS) and Internal Web Server (IWS) Portal Page Parameters can be
digitally signed, preventing malicious subscribers from intercepting, forging and replaying
URL redirection strings used by the NSE and EWS or IWS Portal Page to validate subscriber
access. This capability eliminates a vulnerability that was previously exploited to gain
unauthorized Internet access at charge-for-use sites.
The signing feature can create a cryptographically strong signature that protects the sensitive
portions of a URL redirection string (i.e., NSE ID, MAC address of the subscriber, etc), while
letting the EWS/Portal Page verify that the URL string has not been tampered or forged by the
subscriber.
The feature is configured by selecting a signing method, the parameters to be signed, and
assigning a secret key.
Two signature methods are supported:

signing.
