摘要：
The present invention discloses a method and system for implementing short message encryption. Both the Mobile Station (MS) and the Mobile Switching Center (MSC) are configured with encryption-decryption modules (1), which can encrypt and decrypt the short message by using the Cipher Key (CK) as the encryption-decryption factor. The CK is variable with the Random value (RAND). The CK is not shared between the receiving end and the sending end in the whole process, so that the encrypted short message has a high confidentiality. In addition, the security of the whole transmission environment can be realized by the selectable configuration.
