Hello all. I have just found on the ietf archives an email discussion about the inclusion of the SPECK Cipher in the tls standards. It's reference is below : https://www.ietf.org/mail-archive/web/tls/current/msg13824.html Even though that this cipher originates from the NSA one cannot find a whitepaper that describes it's full cryptanalysis. In the above discussion Mr. Strömbergson somehow perfunctorily presents two whitepapers that describe the SPECK's cryptanalysis. Although we shall keep in mind that these papers describe a limited round cryptanalysis. Also we shall not forget that a similar cryptanalysis has taken place for the famous AES. Therefore i personally do not see any actual arguments apart from the facts that concerns the algorithm's provenance for not including it in a future tls specification. In conclusion even by this day the SPECK cipher has not been yet fully cryptanalyzed succesfully. Thank you! Yours sincerely, Efthimios Iosifides
