Abstract
A system and method can provide a secure subnet management agent (SMA) in an Infiniband (IB) network. The system can comprise a host channel adapter (HCA) associated with a host, wherein the HCA operates to implement a SMA in its embedded firmware. The HCA can prevent a host administrator or software with root access to the host from changing the embedded firmware on the HCA and modifying one or more states associated with the SMA without being endorsed by a site administrator. Additionally, the SMA is associated with a management key, and the host is not allowed to observe the management key without being endorsed by a site administrator.
