Encryption realization method and apparatus

The embodiments of the invention provide an encryption realization method and apparatus. The encryption realization method comprises: receiving an encryption instruction of a plaintext from a user; according to the encryption instruction, generating a random salt figure, and scheduling a root key; and according to the salt figure and the root key, performing encryption processing on the plaintext, and generating a first cryptograph corresponding to the plaintext, and storing at least one of the salt figure and the first cryptograph in a terminal equipment chip. According to the embodiments of the invention, the cost for declassifying cryptographs is increased so that the safety of a plurality of terminal equipment can be ensured in protocol interconnection.
