TC65I WTK and TLS cipher suite issue | Thales IoT Developer Community
April 1, 2015 - 7:30pm, 2606 views
I am implementing a midlet on a TC65i module.
I am using the following WTK
Product name: WMJAVA
WTK Version : "REVISION 02.004"
Date of WTK generation: 17.4.2012
The midlet sends https requests to a server
For HTTPS on this server the 'weaker' accepted cipher suite is Cipher Suite: TLS_RSA_WITH_RC4_128_SHA (0x0005)
The following cipher suites are rejected by the server security policy
Cipher Suite: TLS_RSA_WITH_AES_128_CBC_SHA (0x002f)
Cipher Suite: TLS_RSA_WITH_AES_256_CBC_SHA (0x0035)
Cipher Suite: TLS_RSA_WITH_3DES_EDE_CBC_SHA (0x000a)
Cipher Suite: TLS_RSA_WITH_RC4_128_MD5 (0x0004)
I presume the Cinterion module TC65i uses Cipher Suite: TLS_RSA_WITH_3DES_EDE_CBC_SHA (0x000a) and from now on the TLS handshake fails with 'close Alert(2,40)'
My question is the following one:
Is there a way to support TLS Cipher Suite: TLS_RSA_WITH_RC4_128_SHA (0x0005) or 'stronger' cipher suite in Cinterion module TC65i WTK?
Thanks for your answer.

Hello,
According to documentation TC65i module supports TLS Protocol Version 1.0. So TLS_RSA_WITH_RC4_128_SHA should also be supported. This module is not the newest one. EHS6 for example supports TLS versions 1.0, 1.1 and 1.2.
Best regards,
