In cryptography , a substitution cipher is a method of encryption by which units of plaintext are replaced with ciphertext , according to a regular system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing an inverse substitution. Substitution ciphers can be compared with transposition ciphers .

Runic alphabet - Wikipedia, the free encyclopedia
The runic alphabets are a set of related alphabets using letters known as runes to write various Germanic languages before the adoption of the Latin alphabet and for specialized purposes thereafter. The Scandinavian variants are also known as futhark or fuþark (derived from their first six letters of the alphabet: F , U , Þ , A , R , and K ); the Anglo-Saxon variant is futhorc or fuþorc (due to sound changes undergone in Old English by the same six letters). Runology is the study of the runic alphabets, runic inscriptions , runestones , and their history.
