The encryption program is based on the famous TEA encryption algorithm, key length 128 bits, safe in the DES algorithm (56). The algorithm safe, simple, efficient, fast encryption and decryption, occupy very little memory, very suitable for embedded systems encryption and decryption, also qualified for the safety of large-scale system performance requirements. Algorithm to prevent the common cryptographic attack. The procedure to be encrypted plaintext, encrypted ciphertext are carried out by a 64-bit data packet encryption and decryption. 128-bit key length, and AES, IDEA rather, to ensure adequate security.
