PPT-Cryptography and Network Security

Sixth Edition by William Stallings Chapter 10 Other PublicKey Cryptosystems Amongst the tribes of Central Australia every man woman and child has a secret or sacred name which is bestowed by the older men upon him or her soon after birth and which is known to none but the fully initiated members of the group This secret name is never mentioned except upon the most solemn occasions to utter it in the hearing of men of another group would be a most serious breach of tribal custom When mentioned at all the name is spoken only in a whisper and not until the most elaborate precautions have been taken that it shall be heard by no one but members of the group The native thinks that a stranger knowing his secret name would have special power to work him ill by means of magic.
