DS/ETS 300841:1998 Telecommunications Security - Integrated Services Digital Network (ISDN) - Encryption key management and authentication system for audiovisual services
A privacy system consists of two parts, the confidentiality mechanism or encryption process for the data, and a key management subsystem. This European Telecommunication Standard (ETS) is based on ITU-T Recommendation H.234 [1] and describes authentication and key management methods for a privacy system suitable for use in narrowband audiovisual services conforming to ITU-T Recommendations H.221 [5], H.230 [6] and H.242 [8]. The confidentiality specification is independent, and is contained in the separate ITU-T Recommendation H.233 [7].
