Definition ∞ An RSA Group Signature is a cryptographic scheme that allows members of a defined group to collectively sign messages anonymously while maintaining traceability to the group itself. This system enables any group member to generate a valid signature on behalf of the group. A designated group manager can later identify the specific signer if necessary, revoking anonymity.
Context ∞ RSA Group Signatures find application in scenarios requiring anonymous authentication within a controlled environment, such as privacy-preserving voting systems or secure communication protocols. While not widely adopted in public blockchains due to computational overhead, research continues into its potential for enhancing privacy and accountability in specific decentralized applications. The balance between anonymity and accountability remains a key discussion point.
