Abstract: A method and a device for key generation are disclosed in embodiments of the present invention. The method for key generation is applied to a UMTS-LTE resource convergence scenario that has a base station as an anchor point, and includes: deriving, according to a root key and a count value of an LTE system, or according to a random number and an LTE system root key, a UMTS integrity key and cipher key, and sending the UMTS integrity key and cipher key to a UMTS control node. The embodiments of the present invention enable the derivation of the UMTS integrity key and cipher key in a UMTS-LTE resource convergence scenario that has a base station as an anchor point, enable a user equipment to communicate securely through a UMTS, and further improve security of data transmitted in the UMTS.
