The enforcement mode of the invention relates to the field of information processing on the whole, and further relates to an access request verification method, an authorization information generation method, an access request verification system and hardware equipment. The access request verification method comprises the following steps: acquiring current clock information; receiving a first access request, wherein the first access request comprises a first input code; and judging whether to authorize the first access request according to the current clock information and the first input code. Compared with the prior art, the access request verification method and system, the authorization information generation method and the hardware equipment at least have two advantages as follows: at first, more fine-grained and flexible control to the authorization can be carried out, and then the first input code or a code for verification is generated on the basis of clock information. Therefore, the off-line verification management can be realized.
