Annotation

This JTU-T Recommendation I International Standard specifies a protocol to be used by End Systems and Intermediate Systems in order to provide security services in the Network layer, which is defined by CCITT Rec. X.213 I ISODEC 8348, and IS0 8648. The protocol defined in this ITU-T Recommendation I International Standard is called the Network Layer Security Protocol (NLSP). This ITU-T Recommendation I International Standard specifies:

1) Support for the following security services defined in CClTT Rec. X.800 I ISO 7498-2:

a) peer entity authentication;

b) data origin authentication;

c) access controI;

d) connection confidentiality;

e) connectionless confidentiality;

f) traffic flow confidentiality;

g) connection integrity without recovery (including Data Unit Integrity, in which individual SDUs on a connection are integrity protected):

h) connectionless integrity.

2) The functional requirements for implementations that claim conformance to this ITU-T Recommendation 1 Inteernational Standard.

The procedures of this protocol are defined in terms of

a) requirements on the cryptographic techniques that can be used in an instance of this protocol;
