16 | Alexey Melnikov | Technical Summary A certain maximum amount of data can be safely encrypted when encryption is performed under a single key. This amount is … Technical Summary A certain maximum amount of data can be safely encrypted when encryption is performed under a single key. This amount is called "key lifetime". This specification describes a variety of methods to increase the lifetime of symmetric keys. It provides two types of re-keying mechanisms based on hash functions and on block ciphers, that can be used with modes of operations such as CTR, GCM, CBC, CFB and OMAC. This document is a product of the Crypto Forum Research Group (CFRG) in the IRTF. Research Group Summary The document was reviewed by active CFRG participants. It has CFRG consensus. The document conforms to requirements from RFC 5743. Document Quality draft-irtf-cfrg-re-keying was discussed at several face-to-face CFRG meetings (and one side meeting) and received quite a bit of review from CFRG. Version -08 was reviewed by Yaron Sheffer from the Crypto Review Panel. The document was updated and raised issues were addressed. draft-irtf-cfrg-re-keying-11 was RGLCed in February 2018. Several CFRG participants agreed that the document is ready to publish. Spencer Dawkins did IRSG review of the document during IRSG Poll. The draft was revised and his comments were addressed. Personnel Alexey Melnikov is the document shepherd. Colin Perkins is the responsible IRTF Chair. |

However, IANA has a question about the document. Section 6 of the current draft defines a series of mechanisms that can be used to extend the lifetime of symmetric keys. Is there a chance that a future document would add new mechanisms to the list of those made available by Section 6? If so, would a registry of those modes be useful to future protocol and software developers? If there are no registry actions, while it's often helpful for a document's IANA Considerations section to remain in place upon publication even if there are no actions, if the authors strongly prefer to remove it, we do not object. If this assessment is not accurate, please respond as soon as possible. Thank you, Amanda Baber Lead IANA Services Specialist |
