Research on design and analysis of lightweight hash functions

在传感器网络和RFID网络等资源受限的网络中，需要轻量级的密码原语来实现安全通信。在这项研究中，轻量级散列函数（Lesamnta-LW，DbMMO）的建议，并在适当的模型下的安全性进行了分析。另一方面，我们分析了KATAN，这是一个轻量级的分组密码，从DbMMO的需求的角度来看，安全性。此外，我们通过分析分组密码的内部结构，证明了量子计算机对某些分组密码的安全性的破坏。

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.
