Advanced Encryption Standard (AES) Ciphersuites for Transport Layer Security (TLS)
Alternative Format: Original Text Document
RFC 3268 AES Ciphersuites for TLS June 2002 4. Currently the DHE ciphersuites only allow triple DES (along with some "export" variants which do not use a satisfactory key length). At the same time the DHE ciphersuites are the only ones to offer forward secrecy. This document proposes several new ciphersuites, with the aim of overcoming these problems. Cipher Usage The new ciphersuites proposed here are very similar to the following, defined in [TLS]: TLS_RSA_WITH_3DES_EDE_CBC_SHA TLS_DH_DSS_WITH_3DES_EDE_CBC_SHA TLS_DH_RSA_WITH_3DES_EDE_CBC_SHA TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA TLS_DH_anon_WITH_3DES_EDE_CBC_SHA All the ciphersuites described here use the AES in cipher block chaining (CBC) mode. Furthermore, they use SHA-1 [SHA-1] in an HMAC construction as described in section 5 of [TLS]. (Although the TLS ciphersuite names include the text "SHA", this actually refers to the modified SHA-1 version of the algorithm.) The ciphersuites differ in the type of certificate and key exchange method. The ciphersuites defined here use the following options for this part of the protocol: CipherSuite Certificate type (if applicable) and key exchange algorithm TLS_RSA_WITH_AES_128_CBC_SHA RSA TLS_DH_DSS_WITH_AES_128_CBC_SHA DH_DSS TLS_DH_RSA_WITH_AES_128_CBC_SHA DH_RSA TLS_DHE_DSS_WITH_AES_128_CBC_SHA DHE_DSS TLS_DHE_RSA_WITH_AES_128_CBC_SHA DHE_RSA TLS_DH_anon_WITH_AES_128_CBC_SHA DH_anon TLS_RSA_WITH_AES_256_CBC_SHA RSA TLS_DH_DSS_WITH_AES_256_CBC_SHA DH_DSS TLS_DH_RSA_WITH_AES_256_CBC_SHA DH_RSA TLS_DHE_DSS_WITH_AES_256_CBC_SHA DHE_DSS TLS_DHE_RSA_WITH_AES_256_CBC_SHA DHE_RSA TLS_DH_anon_WITH_AES_256_CBC_SHA DH_anon Chown Standards Track
