1.14.8 SSL / TLS
TOBY-R2 series modules support the Secure Sockets Layer (SSL) / Transport Layer Security (TLS) with certificate
key sizes up to 4096 bits to provide security over the FTP and HTTP protocols.
The SSL/TLS support provides different connection security aspects:
 Server authentication: use of the server certificate verification against a specific trusted certificate or a
trusted certificates list
 Client authentication: use of the client certificate and the corresponding private key
 Data security and integrity: data encryption and Hash Message Authentication Code (HMAC) generation
The security aspects used during a connection depend on the SSL/TLS configuration and features supported.
Table 13 contains the settings of the default SSL/TLS profile and Table 14 to Table 18 report the main SSL/TLS
supported capabilities of the products. For a complete list of supported configurations and settings see the
u-blox AT Commands Manual [2].
