This invention relates to a method for transmitting secret information (I_S) over a communication channel between a transmitter and a receiver, comprising :
- determining by said transmitter a syntax graph G(T_S) from an information support T_S, wherein the nodes of said syntax graph G(T_S) represents the n-grams of a given size in said information support T_S,
- encrypting said secret information I_S in a secret number N ,
- determining by said transmitter a rotation from said secret number N, the number N relative to the secret information I_S being smaller than the maximum number of rotations B(T_S), and decomposing said secret number N into a sequence representative of the permutations on each of the n-grams' outgoing edges,
- applying said sequence on each of the n-grams' outgoing edges of the syntax graph G(T_S) in order to produce a rotated information T'_S. |
