Group Authentication

Definition ∞ Group authentication is a security mechanism that verifies the identity of multiple users or devices collectively before granting access to a shared resource or system. In decentralized environments, this could involve multi-signature schemes or specialized cryptographic protocols for collective authorization. It enhances security by requiring consensus from several participants for critical actions. This method reduces reliance on a single point of control.
Context ∞ The concept of group authentication is particularly relevant in decentralized autonomous organizations (DAOs) and multi-party computation scenarios. Discussions focus on designing secure and efficient methods for collective decision-making and asset management. News reports sometimes highlight innovative cryptographic solutions that enable secure group access and control within blockchain applications.
