PERMIS
PERMIS (PrivilEge and Role Management Infrastructure Standards) is a sophisticated policy-based authorisation system that implements an enhanced version of the U.S. National Institute of Standards and Technology (NIST) standard Role-Based Access Control (RBAC) model. PERMIS supports the distributed assignment of both roles and attributes to users by multiple distributed attribute authorities, unlike the NIST model which assumes the centralised assignment of roles to users. PERMIS provides a cryptographically secure privilege management infrastructure (PMI) using public key encryption technologies and X.509 Attribute certificates to maintain users' attributes. PERMIS does not provide any authentication mechanism, but leaves it up to the application to determine what to use. PERMIS's strength comes from its ability to be integrated into virtually any application and any authentication scheme like Shibboleth (Internet2), Kerberos, username/passwords, Grid proxy certificates and Public Key Infrastructure (PKI).

Similitude (Star Trek: Enterprise)
"Similitude" is the tenth episode from the third season of the television series Star Trek: Enterprise. It first aired on November 19, 2003 and was the sixty-second episode of the series.
Plot
Commander Tucker, while endeavoring to increase to stable speed of Enterprise to Warp 5, becomes comatose when the engines destabilize and explode. Doctor Phlox suggests a radical and controversial procedure to save him - growing a mimetic symbiote as a neurological donor. Archer, concerned with the overarching goal of their mission, gives the order to do so. The symbiote, with a natural life-span of two weeks, is then injected with Tucker's blood and is soon born. Phlox names him "Sim", and as he develops rapidly, Tucker's memories and personality begin to express themselves (including an interest in engineering, and a romantic attraction to Sub-Commander T'Pol).
The window of time approaches when Phlox must perform the transplant, which, according to him, will unfortunately now be fatal to Sim-Trip. Sim, having now 'met' himself in sickbay, reveals knowledge of an experimental procedure that might allow for an extension (presumably by decades) of his lifespan. Archer learns that Phlox was aware of this procedure, but concealed his knowledge of it due to its highly experimental and poorly researched nature. Sim then expresses a strong desire to live —Tucker's own life notwithstanding—through the rest of his natural life. Later, a tired-looking Archer, angered at finding Sim in Trip's quarters, states he would rather Sim voluntarily submit to the fatal procedure than be forced to do so.
