Overview
This document outlines the ways to modify and use Single Channel communications. For information on using the Single Channel image within the Taskbar see Taskbar How to Guide
Architecture
Single Channel images are provided from PINsafe, and are either:
- Requested from the client such as in a web page link to PINsafe
- Proxied by the Access device
There fore PINsafe is usually deployed in the DMZ and the PINsafe Appliance is used with its proxy for additional protection.
Setup Single Channel
The first step is usually to turn on Allow session request by username
On the PINsafe appliance select Server/Single Channel then Allow session request by username and set to Yes, then click Apply.
PINsafe Administration Console Settings
Multiple Authentications per String: Default No. This allows several authentication requests to be made in short succession (in a few seconds)
Single Channel image options
PINsafe 3.6 introduces several new features in the generation of Single Channel Images:
Image File: The image used for displaying the Single Channel Security string, options are:
- Turing (for further customisation see Single Channel Customisation How to Guide)
- button
- pattern
- pattern2
Rotate Letters: Rotate the security string characters
Only use one font per image: Allow the use of multiple fonts in a security string
Jiggle characters within slot: This varies the vertical alignment of characters inthe security string
Add blank trailer frame to animated images: When using animated images this adds a blank frame at the end of the complete cycles so the security string is not visible at the end of the cycles.
Text Alpha Value: This is how dark the characters are, low value is a light character, and a high value a dark character
Number of complete display cycles: The number of times an animated image will be cycled
Number of complete display cycles per image: This determines how many times the security string is displayed when animated
Inter-frame delay (1/100s): The delay between each animation frame
Image Rendering: The pattern used to animate the image, options are:
- Static = no animation
- Ripple = ripples through the security string
- Random = shows N random characters per frame
- Fade-Up = images slowly appear
Generate animated images:
Random glyph order when animating: Display characters in random positions in the security string rather than in sequence
No. Characters Visible: The number of characters visible at one time
Testing and Requesting Single Channel Images
The single channel image is requested by using the following request to the PINsafe server:
http://<PINsafe server IP>:8080/pinsafe/SCImage?username=<username>
example: http://turing.swivelsecure.com:8080/pinsafe/SCImage?username=test
For a PINsafe appliance the request is usually:
https://<PINsafe server IP>:8443/proxy/SCImage?username=<username>
