“…Only a few of them have their own security mechanisms for controlling agent execution on the MAP. Among them are Semoa (Roth and Jalali-Sohi 2001), which uses filters and agent grants on each node of the MAP, Cougaar (Helsinger et al 2004), which utilizes authentication and encryption, Soma (Bellavista et al 1999), which applies a policy to protect agents from each other, CapNet (Contreras et al 2004), which has a policy manager and agent credentials, and so on.…”
