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 35.240: "Specification of the Snow 5G based 256-bits algorithm set: Specification of the 256-NEA4 encryption, the 256-NIA4 integrity, and the 256-NCA4 authenticated encryption algorithm for 5G; Document 1: Algorithm Specification".
3GPP TS 35.241: "Specification of the Snow 5G based 256-bits algorithm set: Specification of the 256-NEA4 encryption, the 256-NIA4 integrity, and the 256-NCA4 authenticated encryption algorithm for 5G; Document 2: Implementation Test Data".
3GPP TS 35.242: "Specification of the Snow 5G based 256-bits algorithm set: Specification of the 256-NEA4 encryption, the 256-NIA4 integrity, and the 256-NCA4 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-NEA4, 256-NIA4 and the combined authenticated encryption 256-NCA4 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.
