| Abstract(in English) | Public-key cryptosystem is an important core technology, which enhances the security of information network. In this talk, we introduce some recent implementations of public-key cryptosystems (e.g. RSA, ECC) on ubiquitous devices such as RFID, ubiquitous sensor nodes, etc. Further, we explain about side channel attacks (SCA) that are new serious attacks on the implementation of cryptosystems on ubiquitous devices. SCA try to detect the secret key based on the computation time or the power consumption of the cryptography operations. It is possible to break the cryptosystem in the implementation level without breaking the underlying mathematical problems e.g., the factoring problem. Finally, we introduce pairing-based cryptosystems that are able to cause the paradigm sift in the security technology. We can achieve some novel cryptographic protocols such as ID based cryptosystems and efficient broadcast encryption. Pairing-based cryptosystems using the η_T pairing over supersingular curves can be implemented as efficient as the conventional public-key cryptosystems. |
