Hi all, Thank you for valuable comments on our proposal of CLEFIA ciphersuites: http://tools.ietf.org/id/draft-katagi-tls-clefia-00.txt. In our draft above, we proposed a lot of combinations with SHA-1. In response to the comments from the TLS working group, we would like to remove the following sets of SHA-1 based ciphersuites: - All combinations involving CLEFIA_256 (from viewpoint of equivalent security to SHA-1) - Combinations involving not commonly used public key primitives Our updated proposal of SHA-1 based ciphersuites is as follows. CipherSuite TLS_RSA_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_DHE_DSS_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_DHE_RSA_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_DH_anon_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_ECDHE_ECDSA_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_ECDHE_RSA_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_PSK_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; CipherSuite TLS_DHE_PSK_WITH_CLEFIA_128_CBC_SHA = {TBD,TBD}; We are going to update this change in the next version of our draft.
