Abstract
A method and system for providing limited access privileges with an untrusted terminal allows a user to perform privileged operations between the untrusted terminal and a remote terminal in a controlled manner. The user can establish a secure communications channel between the untrusted terminal and a credentials server to receive credentials therefrom. Once the user receives the credentials, the secure communications channel is closed. The user can then use the credentials to perform privileged operations on a remote terminal through the untrusted terminal. The remote terminal knows to grant the user limited privileges based on information included in the credentials. The effects of malicious actions by the untrusted terminal are limited and controlled.
