Embodiment Construction
[0031] like figure 1 As shown, a method for safe transmission of multimedia data includes the following steps:
[0032] First, the input voice signal is collected by the sound sensor, and then the following encryption method is used to encrypt the voice signal. Let N initial signals s 1 (t),…,s n (t) and M key signals k 1 (t),…,k M (t), the encryption formula is:
[0033] X(t)=[x 1 (t),…,x N (t)] T =As k (t)
[0034] Among them, X(t) represents N encrypted signals, s k (t)=[s 1 (t),…,s n (t),k M (t)] T , A is an N×(M+N) encryption matrix, and each value is between [-1, 1]. Let A = [A S ,A k ], where A S is an N×N matrix, A k is an N×M matrix, and the encryption formula is represented by the following formula:
[0035] X(t)=A s s(t)+A k k(t),
[0036] Among them, s(t)=[s 1 (t),…,s n (t)] T , k(t)=[k 1 (t),…,k M (t)] T
[0037] Let, N=M, establish the following encryption matrix:
[0038]
[0039] Among them, A is an N×2N matrix, B is a 1×N matri...
