Lustre file system can improve I/O throughput in the clusters effectively, but there still be some security problems in TCP/IP network environment, such as identity theft, data interception, data modification and replay-attack. Lustre is planning to use Kerberos security mechanism which can not solve some problems in enterprise-wide, such as overhead, digital signature and password attack. To the...
Although IPv6 protocol has considered and implemented more security mechanisms compared with IPv4, there are still many security threatens in IPv6 networks. Being one of the key protocols in IPv6, the Internet control message protocol (ICMPv6) suffers from severe security risks. In this paper we construct an IPv6 attacking test system H6Proxy exploiting the ICMPv6 unreachable message, which shows...
TCP is a popular Internet protocol for reliable end-to-end data delivery. However, the protocol is designed based on wired link, so it is not suitable for mobile network. The main problem is that the frequent handover of mobile nodes may cause poor TCP performance. In order to eliminate the inefficiency of TCP in mobile environment, a modified TCP scheme for improving its performance, named as MTCP,...
