Abstract:  This report gives an overview of the current research and trends in
the area of TCP/IP security. The basic issues in network security and
encryption techniques are presented as background material. The leading
contenders in the field of secure internet protocols are then reviewed.
The review includes the security architecture proposed in the draft standard
for the next version of the internet protocol (IPv6). Issues in key management
for the encryption and message digests employed in IP security architectures
are presented with a brief overview of the ANSI X9.17 standard and the use of
key management protocols in SNMP and Kerberos. Finally an overview of possible
implementation scenarios for IP security are presented.
