SCL: A Secure Concurrency Layer For Paranoid Stateful Lambdas. (arXiv:2210.11703v1 [cs.CR])

We propose a federated Function-as-a-Service (FaaS) execution model that
provides secure and stateful execution in both Cloud and Edge environments. The
FaaS workers, called Paranoid Stateful Lambdas (PSLs), collaborate with one
another to perform large parallel computations. We exploit cryptographically
hardened and mobile bundles of data, called DataCapsules, to provide persistent
state for our PSLs, whose execution is protected using hardware-secured TEEs.
To make PSLs easy to program and performant, we build the familiar Key-Value
Store interface on top of …
