Signature System and Signature Method |
摘要 |
A signature system in which size of data to be transmitted is small and data can be processed efficiently in a Merkle signature system having high security. A processing part 112 of a smartcard 110 divides a message to be signed into groups of specific numbers of bits, starting from the first bit of the message. Then, respective partial one-time signatures of the groups are generated by encrypting each group by a one-way function processing part 112 c. The partial one-time signatures are sequentially outputted to a verification apparatus through a interface part 113.
