Abstract
A block-based stream encryption/decryption processing method for applying a matrix architecture of diffusion algebra includes the steps of (a) selecting a private key and a pairing private key; (b) selecting a plaintext and multiplying the plaintext with the private key to produce a ciphertext; (c) multiplying the ciphertext with the pairing private key to obtain the plaintext; and (d) repeating the steps (b) and (c) to produce encrypted or decrypted block streams.
Claims20
A block-based stream encryption/decryption processing method, for applying a matrix architecture of diffusion algebra, at least comprising the steps of:
- (a) selecting a private key and a pairing private key;
- (b) selecting a plaintext, and multiplying said plaintext with said private key to produce a ciphertext;
- (c) multiplying said ciphertext with said pairing private key to obtain said plaintext;
- and
- (d) repeating the steps (b) and (c) to produce encrypted and decrypted block streams.
