+ * \warning
+ * LUFA is not a secure USB stack, and has not undergone, not is it expected to pass, any
+ * form of security audit. The CCID class here is presented as-is and is intended for
+ * research purposes only, and *should not* be used in a security critical application
+ * under any circumstances.
+ *
+ * \warning
+ * This code is not production ready and should not by any means be considered safe.
+ * If you plan to integrate it into your application, you should seriously consider strong
+ * encryption algorithms or a secure microprocessor. Since Atmel AVR microprocessors do not
+ * have any security requirement (therefore they don't offer any known protection against
+ * side channel attacks or fault injection) a secure microprocessor is the best option.
