Look up his article "criptographie millitaire" (writen in 1883) at http://www.tcs.hut.fi/~helger/crypto/link/history/index.html it is quite interesting.
the prnciple basically states that a cryptographic protocol's security should not relay on the knowledge of how does the protocol itself is, e.g., you should always suppose that the algorithms and related data used during the protocol's execution (other than specific private data such as private keys) are known to the attackers. This principle is considered a MUST in the construcion of cryptographic protocols and primitives.
