Abstract
A data transfer apparatus includes a first memory, a second memory, a search unit, and a data transmitting/receiving unit. The first memory holds information that associates a search key with an address. The second memory holds information that associates the address with verification information which is generated by a predetermined generation method based on at least a portion of the search key. The search unit generates the search key based on the received data, obtains, from the first memory, the address that is associated with the generated search key, obtains, from the second memory, the verification information that is associated with the obtained address, and verifies the verification information that is generated by the predetermined generation method based on at least a portion of the generated search key with the verification information obtained from the second memory. The data transmitting/receiving unit executes processing based on a result of the verification.
