The conventional cryptography solutions are ill-suited to strict memory, size and power limitations of resourceconstrained devices, so lightweight cryptography solutions have been specifically developed for this type of applications. In this domain of cryptography, the term lightweight never refers to inadequately low security, but rather to establishing the best balance to maintain sufficient ...

Green Cryptography is a technique which enables a natural succession of cryptographic primitives. Cryptographic operations are made energy-efficient in a way that it promises the use of approaches of lightweight cryptography. These Lightweight cryptographic algorithms are certainly worn for the devices which use low or extremely low resources. In this paper we have proposed a watermarking schem...

The design of lightweight block ciphers has been a very active research topic over the last years. However, the lack of comparative source codes generally makes it hard to evaluate the extent to which different ciphers actually reach their low-cost goals, on different platforms. This paper reports on an initiative aimed to partially relax this issue. First, we implemented 11 block ciphers on an...

Security and privacy are going to be the key factors for the deployment of new applications, since people will only accept these deployments if these are based on secure, trustworthy and privacy-preserving infra-structures. Cryptography plays a major role in the security of data transmission and the development of computing technology imposes stronger requirements on the cryptography schemes. L...

Technological advancements in the semiconductor industry over the last few decades made the mass production of very small-scale computing devices possible. Thanks to the compactness and mobility of these devices, they can be deployed “pervasively”, in other words, everywhere and anywhere – such as in smart homes, logistics, e-commerce, and medical technology. Embedding the small-scale devices i...

This paper shows the great potential of lightweight cryptography in fast and timing-attack resistant software implementations in cloud computing by exploiting bitslice implementation. This is demonstrated by bitslice implementations of the PRESENT and Piccolo lightweight block ciphers. In particular, bitsliced PRESENT-80/128 achieves 4.73 cycles/byte and Piccolo-80 achieves 4.57 cycles/byte inc...
