随着密码技术与集成电路的发展,密码设备在人们日常生活中得到了广泛的运用,人们的生活方式也因此大大改变.虽然,目前的密码算法本身已足够强大,能够对抗传统的密码分析手段,但由于设备本身的工艺特性,其运行时会泄露如功耗、电磁、时间等种种侧信道信息,这些信息能够被攻击者利用从而破解密钥.旁路攻击的出现引发了人们对密码算法实现平台的安全进行深入研究.目前有较多对密码算法功耗攻击与防御进行研究的文献,也提出了不少方法,但在防御差分功耗攻击的同时如何使密码算法的实现达到面积、速率与安全的平衡一直是研究的重点.在研究差分功耗攻击与防御的基础上,对AES算法及内部轮函数结构进行研...

With the development of cryptography and integrated circuits, cryptographic devices have been widely used in our daily life and changed the way we live. Although the current cryptographic algorithm is strong enough to resist the traditional cryptanalysis, due to the technologic property of the device itself, it will leak out all kinds of Side-channel information such as power consumption, electromagnetic radiation and time of execution, which can be used by adversary to recover the secret key. Side-channel attacks triggered the designers to further study the security of cryptographic algorithm...
