Abstract
The present invention relates to a decryption method, a cryptosystem and a mobile terminal. The decryption method comprises: inputting a cipher; determining whether the input cipher is a set cipher and whether the set cipher is in an activated state; if yes, decrypting a terminal, invalidating a currently used cipher, and activating another set cipher; and enabling the terminal to be decrypted next time only when a cipher in the activated state is input. With adoption of the technical scheme, worries about revealing the cipher can be removed even if cipher unlocking is seen by others during decryption. Furthermore, even if unlocking traces are left on the screen of an intelligent terminal, others cannot unlock the intelligent terminal. The technical scheme is particularly applicable to a pattern encryption/decryption manner.
