Rapid advances in communication technology have accentuated the need for security in the Internet. The IP Security Protocol Working Group (IPSEC) will develop mechanisms to protect client protocols of IP. A security protocol in the network layer will be developed to provide cryptographic security services that will flexibly support combinations of authentication, integrity, access control, and confidentiality.
The IPSEC working group will restrict itself to the following short-term work items to improve the existing key management protocol (IKE) and IPSEC encapsulation protocols:
1. Changes to IKE to support NAT/Firewall traversal
2. Changes to IKE to support SCTP
3. New cipher documents to support AES-CBC, AES-MAC, SHA-2, and a fast AES mode suitable for use in hardware encryptors
4. IKE MIB documents
5. Sequence number extensions to ESP to support an expanded sequence number space.
6. Clarification and standardization of rekeying procedures in IKE.
The working group will also update IKE to clarify the specification and to reflect implementation experience, new requirements, and protocol analysis of the existing protocol. The requirements for IKE V2 will be revised and updated as the first step in this process.
