Dynamic Pre-shared Key (DPSK)
What it means:
Dynamic Pre-Shared Key (DPSK) is a Ruckus-patented technology that delivers secure network access by providing each device and user with a unique login credential. Users access the wireless network using their own personal key, which is provided as part of the network onboarding process. In contrast, with conventional pre-shared keys (PSKs), multiple, or even all, users share the same key.
Why you should care:
Traditional pre-shared keys create a security hole in network defenses because multiple users access the network with the same key. Conventional PSKs do not give IT teams visibility and control over devices on the network or the ability to map access policies to specific users and devices. Users readily share conventional PSKs with others, and IT cannot revoke them for one user without revoking access for all. DPSKs address the security flaws of conventional PSKs to make users, devices, data and the network more secure.
DPSKs are an alternative to digital certificates that provide similar security benefits. They are appropriate in cases where user experience considerations make it impractical to install a digital certificate on the device. This applies in cases where the user will only need network access for a limited time—for example, in the case of guest users.
