Abstract
An apparatus and method are provided for reducing time taken for generating a digital signature and generating the digital signature using a minimum number of operations using at least two secret keys. One secret key among at least two secret keys may be set from a value resulting from hashing a message to be transmitted. A number of times for hashing the secret key is determined, and a value resulting from hashing the determined secret key by the determined hashing number of times is set as the digital signature.
