Good crypto protocols are very much designed to not be trivial to break even with some known plain text. It is a known obvious attack so they are designed to protect against exactly that.
Yep, they've been doing that for centuries. With a polyalphabetic cipher, each time a letter occurs in the plain text, a different letter is used in the cipher text. This makes it impossible to use the statistical methods used with monoalphabetic ciphers, where a plain text letter always has the same cipher text letter.
