Abstract: Techniques of preventing sabotage attacks in cyber-physical systems involve automatically identifying links between nodes of a graph representing cyber-physical systems as vulnerable to sabotage attacks according to a vulnerability metric for each link. The vulnerability metric used depends on the particular sabotage attack used to determine the vulnerable links. Once a computer configured to design cyber-physical systems based on vulnerability to sabotage attacks receives data representing the graph, the computer enumerates the possible links between nodes of the graph along which a sabotage attack may be performed. For each of those links, the computer computes the vulnerability metric. The computer then ranks the links according to respective values of the vulnerability metric. Based on the ranking, a designer may then perform a mitigation analysis that results in changes to the graph to reduce the vulnerability at each node accessible to a malicious actor.

Abstract: Exemplary embodiments relate to the secure storage of security questions through an immutable log, such as a blockchain. The security questions may be stored in a centralized location, accessible from an application or browser tab running on the user's device. When a security question is required, such as to perform a password reset on a website, the website may interact with the application or browser tab, which retrieves the question(s) from the blockchain.

Thus, the requesting website sees neither the questions nor the answers. Additional security features may include logging requests for questions, so that a user can determine if a security question may have been compromised.

Once the password is received, the Gatekeeper performs a password verification procedure.

Abstract: A device unlock pattern (“pattern password”) is static in that the same pattern is entered each time to unlock a device. Due to this repetition, a pattern password may be discovered by an application that captures touchscreen gestures, by inspection of fingerprints or smudges on a screen, or simply by an onlooker that views the pattern password being entered. A variable hint pattern can be used to impede discovery. A hint pattern is a sub-pattern (“hint”) of the pattern password to be completed for device unlock. A variable hint pattern can impede discovery by changing the sub-pattern at a defined change threshold related to unlock attempts. The device can randomly change the sub-pattern or randomly change the missing portions of the pattern password at each change threshold. As a result, different inputs complete the pattern password. This variance stymies the methods typically used to discover pattern passwords.

Abstract: Techniques for resetting authentication for touch-enabled devices are presented. When a user authenticates to a mobile device a touch profile (TP) is recorded. Each subsequent time the user unlocks a locked mobile device via touch, a new TP is noted. The new TP is compared to the recorded TP and if the deviation is within an acceptable tolerance, the user is permitted access to the mobile device without re-authentication. When the new TP is not within the acceptable tolerance of the recorded TP, the user is forced to re-authenticate before access is granted to the mobile device.
