DelegaTEE: Brokered Delegation Using Trusted Execution Environments
summary
System implements brokered delegation with Intel SGX enclaves and a central or peer-to-peer proxy that stores owner credentials but credentials never revealed to delegatees; owners upload credentials, attach rich contextual policies (time, amount, regexp filters) and the enclave performs HTTPS logins and payments on behalf of delegatees. Full implementation handles SMTP/IMAP, HTTPS proxy, credit cards and PayPal (browser extension intercepts CAPTCHA and executes payment). Performance overhead is small; central brokers face bandwidth limits; SGX side‑channel risks remain.
