This is certainly true for AES, mostly because many small chips are including AES accelerators in hardware. It's not quite true for public key solutions; there are still very small devices where even ECC takes too long (and yes, there are cases where 200-400ms is still too long). > It pays to look again at David Wagner's slides from 2005, on sensor > nets and crypto: > https://people.eecs.berkeley.edu/~daw/talks/sens-oak05.pdf > > > --Steve Bellovin, https://www.cs.columbia.edu/~smb -derek -- Derek Atkins 617-623-3745 de...@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
