[rfced] Section 8.3.1.1: For ease of the reader, we expanded
"HPKE" as "Hybrid Public Key Encryption". If this is incorrect,
please provide the correct definition.

Original:
In the case of a Group Operation message,
only the privacy is affected, as the signature is revealed, because
the secrets themselves are protected by HPKE encryption.

Currently:
In the case of a Group Operation message,
only the privacy is affected, as the signature is revealed, because
the secrets themselves are protected by Hybrid Public Key Encryption
(HPKE).
