| Abstract(in English) | Recently there are a lot of secure digital signature schemes proved by a security notion. The standard security notion for digital signature schemes is existential unforgeability under chosen message attacks (EUF-CMA). In this notion, it is assumed that the information such that random numbers and a secret key used in signing does not leak. However, in practice, key exposure could be caused by human error. Moreover, there exists side-channel attacks (e.g.SPA/DPA attack, EMA attack) which exploit leakage of information about the secret internal state. It is important to consider about countermeasures of leaks of the information.Forward-Secure Signatures and Leakage-Resilient Signatures are countermeasure for these threats. In this research, we propose Forward-Secure Leakage-Resilient Signature scheme which satisfies both properties described above, and give a construction using CML Leakage-Resilient scheme. Finally, we give a securty proof. |
