These documents include requirements for the overal
22、l IPv6 security architecture 1, the use of the IP Authentication Header (AH) 2, IP Encapsulating Security Payload (ESP) 3, the use of cryptographic algorithms 4, 6 and the Internet Key Exchange (IKEv2) 5. The present document is a catalogue of all of the normative requirements from these security sp
23、ecifications. Each requirement is given a unique identifier (for example, RQ_002_1234) and the following information is included with each: the clause number in the RFC from which the requirement has been extracted; the type of requirement (Mandatory, Optional or Recommended); the type of device to
24、which the requirement applies (for example, Host or Router); the actual text from which the requirement was extracted.

27、ing these keys in place. This document requires support for both manual and automated distribution of keys. It specifies a specific public-key based approach (IKEv2 Kau05) for automated key management, but other automated key distribution techniques MAY be used. - Identifier: RQ_002_1011 RFC Clause:

30、use: 4.1 Type: Mandatory Applies to: IPsec host Requirement: A Security Association MUST apply to exactly one of ESP or AH RFC Text: An SA is a simplex “connection“ that affords security services to the traffic carried by it. Security services are afforded to an SA by the use of AH, or ESP, but not
31、both. If both AH and ESP protection are applied to a traffic stream, then two SAs must be created and coordinated to effect protection through iterated application of the security protocols. To secure typical, bi-directional communication between two IPsec-enabled systems, a pair of SAs (one in each
32、 direction) is required. IKE explicitly creates SA pairs in recognition of this common usage requirement. - Identifier: RQ_002_1020 RFC Clause: 4.1 Type: Mandatory Applies to: IPsec host Requirement: A host implementation of IPsec MUST support transport mode RFC Text: In summary, a) A host implement
33、ation of IPsec MUST support both transport and tunnel mode. This is true for native, BITS, and BITW implementations for hosts. b) A security gateway MUST support tunnel mode and MAY support transport mode. If it supports transport mode, that should be used only when the security gateway is acting as
34、 a host, e.g., for network management, or to provide security between two intermediate systems along a path. - Identifier: RQ_002_1021 RFC Clause: 4.1 Type: Mandatory Applies to: IPsec host Requirement: A host implementation of IPsec MUST support tunnel mode RFC Text: In summary, a) A host implement

41、an IPsec Host sends an IP packet containing an Authentication Header (AH), it MUST set the appropriate Next Header field (either in the IPv6 Header or in the previous Extension Header) to the value fifty-one (51) RFC Text: The protocol header (IPv4, IPv6, or IPv6 Extension) immediately preceding the
42、 AH header SHALL contain the value 51 in its Protocol (IPv4) or Next Header (IPv6, Extension) fields DH98.
