WEP Naming Conventions

There is some confusion among various vendors with regard to referring to encryption strength. You will see vendors variously referring to 40-, 64-, 104-, and 128-bit encryption. In reality, vendors refer to 40- and 64-bit and 104- and 128-bit encryption interchangeably. The length of the secret keys will be 40 or 104 bits (depending on the strength of encryption), but each will use a 24-bit vector initialization vector (e.g., 40 plus 24 = 64 and 104 plus 24 = 128).
