Rac, PAK, and eNOS ACTion.

Rac1 is a member of the Rho family of GTPases, which includes Rho, Rac, and cdc42 subfamilies.1,2 On activation by guanine nucleotide exchange factors, the Rho family GTPases exchange a GDP molecule for a GTP and act as molecular switches to transduce signals in response to various extracellular stimuli.2 Apart from their characteristic role in the regulation of cytoskeletal rearrangement and c...

Tightly-Secure PAK(E)

We present a security reduction for the PAK protocol instantiated over Gap Diffie-Hellman Groups that is tighter than previously known reductions. We discuss the implications of our results for concrete security. Our proof is the first to show that the PAK protocol can provide meaningful security guarantees for values of the parameters typical in today’s world.
