In this paper, we propose a design method for the signature scheme based on ring structure Zn. Our signature schemes are more secure, generate signatures at a faster rate than that of the ElGamal scheme and its variants. Moreover, our approaches also overcome some disadvantages of some similar signature schemes on ring Zn. For these advantages, they are fully applicable in practice.

Blockchain technology has been applied widely in many countries in different fields such as banking, finance, insurance, health, production, retailing... However, the application of this technology in education seems to be still limited, especially in Vietnam. This paper will introduce an overview of blockchain technology as well as propose some recommendations on the potential of applying this technology to support management activities at universities in Vietnam. Finally, the advantages and disadvantages of deploying blockchain technology at universities in Vietnam will also be mentioned.

This paper proposes a block crypto system that uses cyclic geometric progressions over polynomial rings as encryption function, and its encryption diagram is based on unbalanced Feistel network with four branches. All the sub keys in encryption steps are also elements in cyclic geometric progressions over polynomial ring with two cyclotomic cosets. By using this crypto system, we apply to a hash function with 512 bits output length. Some diffusion simulations of the proposed crypto system and hash function are also presented.

Cryptography, in particular public-key cryptography, has emerged in the last 20 years as an important discipline that is not only the subject of an enormous amount of research, but provides the foundation for information security in many applications. Standards are emerging to meet the demands for cryptographic protection in most areas of data communications.

We describe a novel mechanism called Reservoir Counting for application in online Locality Sensitive Hashing. This technique allows for significant savings in the streaming setting, allowing for maintaining a larger number of signatures, or an increased level of approximation accuracy at a similar memory footprint.

Previous work on consistent hashing assumed that nodes were aware of most other nodes in the system, making it impractical to scale to large number of nodes. In contrast, each Chord node needs “routing” information about only a few other nodes. Because the routing table is distributed, a node resolves the hash function by communicating with a few other nodes. In the steady state, in an  -node system, each node maintains information only about     other nodes, and resolves all lookups via     messages to other nodes.

Cryptographic hash functions play a fundamental role in modern cryptography. While related to conventional hash functions commonly used in non-cryptographic computer applications – in both cases, larger domains are mapped to smaller ranges – they differ in several important aspects. Our focus is restricted to cryptographic hash functions (hereafter, simply hash functions), and in particular to their use for data integrity and message authentication.

This module explains to students how to strengthen the security of their Web applications by incorporating the programmatic use of cryptography. Depending on the programming platform, students will use one of several cryptographic libraries to add encryption, hashing, and digital signing functionality to their Web application. After completing this module, students will be able to use the CAPICOM cryptographic library and the System.Security.Cryptography namespace to encrypt, hash, and sign data....
