Kerckhoff’s Principle

During the 19th century, a Dutch cryptographer named Auguste Kerckhoff identified the requirements of a reliable cryptosystem. He stated that a cryptosystem must be secure even if everything related to it – except the keys – are available to the public. In addition, Mr. Kerckhoff established six principles in designing new cryptosystems. These principles are:

The cryptosystem needs to be unbreakable (i.e. in a practical sense). This excludes the system’s vulnerability to mathematical intrusions.

The system should be secure enough that members can still use it even during an attack from unauthorized entities. The cryptosystem needs to allow authorized members to do what they need to do.

The keys used in the system must be easy to change, memorize, and communicate.

The resulting ciphertexts must be transmissible by unsecure channels such as telegraph.

The documents and devices used in the encryption system must be portable and easy to operate.

Lastly, the system must be user-friendly. It should not require high IQ or advanced memorization skills.
