| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Lifelog and office information systems store processing data. Because these systems process data with these stored data, integrity of stored data is very important. A hash function that is the cryptographic algorithm is used for integrity. On the other hand, a security of a hash function is weakening because of compromising of cryptosystems. In this paper, we compare the computational complexity of attack against hash function MD5 and SHA-1, and consider attack feasibility and the security risk against practical system. |
