0  Introduction  p. 5

The present document is one of three, which between them form the entire specification set of the encryption and integrity protection algorithms, entitled:
  • 3GPP TS 35.243: "Specification of the AES based 256-bits algorithm set: Specification of the 256-NEA5 encryption, the 256-NIA5 integrity, and the 256-NCA5 authenticated encryption algorithm for 5G; Document 1: Algorithm Specification".
  • 3GPP TS 35.244: "Specification of the AES based 256-bits algorithm set: Specification of the 256-NEA5 encryption, the 256-NIA5 integrity, and the 256-NCA5 authenticated encryption algorithm for 5G; Document 2: Implementation Test Data".
  • 3GPP TS 35.245: "Specification of the AES based 256-bits algorithm set: Specification of the 256-NEA5 encryption, the 256-NIA5 integrity, and the 256-NCA5 authenticated encryption algorithm for 5G; Document 3: Design Conformance Test Data".

1  Scope  p. 6

The present document contains the algorithm specification which could be used as the encryption and integrity protection function 256-NEA5, 256-NIA5 and the combined authenticated encryption 256-NCA5 protection function for 3GPP systems.

2  References  p. 6

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
  • References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
  • For a specific reference, subsequent revisions do not apply.
  • For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
