1 Scope p. 7

The present document specifies the security architecture, i.e., the security feature groups and the security mechanisms performed during inter working between non-3GPP accesses and the Evolved Packet System (EPS).

2 References p. 7

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.

3 Definitions, symbols and abbreviations p. 9

3.1 Definitions p. 9

For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.

IPsec Security Association (IPsec SA):

A unidirectional logical connection created for security purposes. All traffic traversing an IPsec SA is provided the same security protection. The IPsec SA itself is a set of parameters to define security protection between two entities. An IPsec SA includes the cryptographic algorithms, the keys, the duration of the keys, and other parameters.

3.4 Conventions p. 10

All data variables in the present document are presented with the most significant substring on the left hand side and the least significant substring on the right hand side. A substring may be a bit, byte or other arbitrary length bitstring. Where a variable is broken down into a number of substrings, the leftmost (most significant) substring is numbered 0, the next most significant is numbered 1, and so on through to the least significant.
