ETSI Releases Security Encryption Specs for 5G and IoT Uses
The specifications are for Attribute-Based Encryption (ABE) that describes how to secure personal data. 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. A standard using ABE avoids binding access to a person’s name, but instead to pseudonymous or anonymous attributes. ETSI says ABE is also space-efficient, since only one ciphertext is needed to cater for all access control needs of a given data set.
