Hi Jeff,

PAKE means password-authenticated key exchange, and TLS-PSK is not 
suitable for use with (short, memorable) passwords. See 
https://tools.ietf.org/html/rfc4279#section-7.2

TLS-SRP is the right tool for that. It is public key based but does not 
require the whole PKI code bloat, so may be a good fit for 
resource-constrained devices.

Thanks,
	Yaron
