| Research Abstract |
Lightweight cryptographic primitives are required to achieve secure communication in the resource-constrained network such as a sensor network and an RFID network. In this research, lightweight hash functions (Lesamnta-LW, DbMMO) are proposed and are analyzed in terms of security under an appropriate model. On the other hand, we analyze the security of KATAN, which is a lightweight blockcipher, from the viewpoint of DbMMO's requirements. Furthermore, we show that a quantum computer compromises the securityof some blockciphers by analyzing the internal structure of a blockcipher.
