Abstract
Embodiments of the present application provide apparatus and methods for generating a shared key, including setting up a key negotiation connection, and determining an algorithm code by negotiating using the key negotiation connection. An algorithm corresponding to the algorithm code is retrieved from a pre-stored algorithm library, and a pre-stored seed key is calculated using the algorithm to obtain a shared key. Compared with traditional key generation methods, embodiments of the present invention avoid the problem of a high bit error rate that occurs in the traditional quantum key generation methods, especially quantum key generation methods. One exemplary method determines an algorithm code through negotiation, retrieves a pre-stored algorithm corresponding to the algorithm code, and generates a new shared key using a seed key.
