Cryptographic Primitives And Quantum Theory [PDF]
Workshop on Physics and Computation, 2005 only using public key cryptography, but using quantum mechanics as a support. This paper summarizes the current knowledge in the field of two-party cryptographic protocols devised f rom quantum systems. W e introduce the reader to the notion of cryptographic protocols and describe a number of sample building blocks to achieve them.

A Study of Cryptographic Backdoors in Cryptographic Primitives
Electrical Engineering (ICEE), Iranian Conference on, 2018Since the revelations of Edward Snowden in 2013, the topic of cryptographic backdoors has been popular in both cyber security and popular culture. However, such backdoors were well known in the cryptology community well before 2013. There are a variety of mechanisms for modifying cryptographic primitives so that the resultant modified algorithm is more

Making Cryptographic Primitives Harder
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008This paper studies a method for transforming ordinary cryptographic primitives to new harder primitives. Such a method is expected to lead to general schemes that make present cryptosystems secure against the attack of quantum computers. We propose a general technique to construct a new function from an ordinary primitive function f with a help of ...

Controlled Operations as a Cryptographic Primitive [PDF]
, 2001 Controlled two-place operations (CTPO) are introduced as a new cryptographic primitive for the block ciphers. Design criteria, structure, some good cryptographic properties of the CTPO are considered. There are proposed CTPO representing single nonlinear operations on the operands of relatively large length.

Implementing Cryptographic Primitives in the Symbolic Model [PDF]
, 2011 When discussing protocol properties in the symbolic (Dolev-Yao; term-based) model of cryptography, the set of cryptographic primitives is defined by the constructors of the term algebra and by the equational theory on top of it. The set of considered primitives is not easily modifiable during the discussion.

Post-Quantum Cryptographic Primitives
2020The necessity of cyber-security is becoming apparent as we grow increasingly dependent on technology in our daily lives. Cybersecurity allows us to protect our digital information that is stored and transferred via the Internet. Because of this growing dependence, this research project endeavours to design, construct and evaluate new post-quantum ...

Conventional Cryptographic Primitives
2010Modern network security systems contain cryptographic primitives as an essential building block. In this chapter, we discuss conventional cryptographic primitives, which are also known as symmetric primitives. The term “symmetric” stems from the fact that in order to use conventional primitives, all parties need to share the same set of secret keys ...

Primitive Constituent Elements of Cryptographic Protocols
2018 IEEE SmartWorld, Ubiquitous Intelligence & Computing, Advanced & Trusted Computing, Scalable Computing & Communications, Cloud & Big Data Computing, Internet of People and Smart City Innovation (SmartWorld/SCALCOM/UIC/ATC/CBDCom/IOP/SCI), 2018Many cryptographic protocols have been proposed, and many studies of them have been done. However, there is no study to identify constituent elements of cryptographic protocols that are elements of the protocols consist of. The constituent elements can be used for the basis of classification of already proposed cryptographic protocols, the basis of ...

On the Homomorphic Computation of Symmetric Cryptographic Primitives
2013We present an analysis on the homomorphic computability of different symmetric cryptographic primitives, with the goal of understanding their characteristics with respect to the homomorphic evaluation according to the BGV scheme. Specifically, we start from the framework presented by Gentry, Halevi and Smart for evaluating AES.
