ETSI releases cryptographic standards for secure access control

The European Telecommunications Standards Institute (ETSI) Technical Committee on Cybersecurity has recently released two specifications on Attribute-Based Encryption (ABE) that describe how to protect personal data securely—with fine-grained access controls. ABE is an asymmetric, multi-party cryptographic scheme that bundles access control with data encryption. In such a system, data can only be decrypted if the set of attributes of the user key matches the attributes of the encryption.
