摘要：
A key-generating apparatus is provided for generating a session key which is known to a first communication apparatus and a second communication apparatus, for the first communication apparatus, from secret information which may be determined by the first and second communication apparatuses. The key-generating apparatus includes a first module operable to calculate the session key using a concatenation of at least a part of a random number and a part of the secret information, and a second module operable to use the session key for communication with the second communication apparatus.
