Re: [TLS] [Cfrg] 3DES diediedie

d even if you don't have an AES core, the ARM can do AES in fewer cycles. This one shows 2270 cycles for AES-128 http://www.cryptovia.com/ARM_Thumb_AES.html Selecting 8/16 bit MCUs like AVR, PIC, 8051 in 2016 for power reasons without looking at modern 32-bit MCUs based on ARM or MIPS is

Re: [TLS] Include Speck block cipher?

HW. I fail to see why anyone would be interested in Speck and would never recommend anyone to use it. But hey, write a draft and try to get an informational RFC for it if it scratches your itch. There are several other RFCs describing ciphers not being used very much. - -- Med vänlig hälsn

Re: [TLS] Include Speck block cipher?

Salsa20 cipher requires about 5 cycles/byte on ARM: https://www.hyperelliptic.org/tanja/vortraege/20121129.pdf But if we wanted algorithms optimized for embedded, small architectures we could look at the ECRYPT eSTREAM profile 2 ciphers: http://www.ecrypt.eu.org/stream/ AFAIK they did get a fai
