With rapid technological advancements and enhanced network growth, security contends to play a crucial role. A powerful network security tends to point out diverse mixture of threats and intimidations and blocks them from creeping and getting circulated into the network to preserve the reliability, confidentiality, integrity, and accessibility of computer networks by annihilating illegitimate admittance and corruption of critical information. Secure hash algorithms (SHA) are cryptographic hash functions used to produce a hash value of fixed output bit sizes. In this paper, an algorithm is proposed to strengthen the cryptographic systems by using reversible logic to generate higher and variable hash values, making it difficult to trace the keys. The proposed scheme is simulated and verified using FPGA Virtex ML505 board, the analysis of power and time of which is carried out using Genus tool, proving it to be efficient in terms of power, gate usage, garbage, and quantum cost.

Energy loss is a big challenge in digital logic design primarily due to impending end of Moore’s Law. Increase in power dissipation not only affects portability but also overall life span of a device. Many applications cannot afford this loss. Therefore, future computing will rely on reversible logic for implementation of power efficient and compact circuits. Arithmetic and logic unit (ALU) is a fundamental component of all processors and designing it with reversible logic is tedious. The various ALU designs using reversible logic gates exist in literature but operations performed by them are limited. The main aim of this paper is to propose a new design of reversible ALU and enhance number of operations in it. This paper critically analyzes proposed ALU with existing designs and demonstrates increase in functionality with 56% reduction in gates, 17 % reduction in garbage lines, 92 % reduction in ancillary lines and 53 % reduction in quantum cost. The proposed ALU design is coded in Verilog HDL, synthesized and simulated using EDA (Electronic Design Automation) tool-Xilinx ISE design suit 14.2. RCViewer+ tool has been used to validate quantum cost of proposed design.

Computer networks are basically not safe to access freely. Security gaps in the network can be seen by irresponsible people with various techniques. Opening a port for access carries a high risk of being attacked by an attacker. In this connection, network administrators are required to work more to be able to secure the computer network they manage. One form of network security that is often used by network administrators in server management is through remote login such as ports on telnet, SSH, etc. A port that is always open is a network security hole that can be used by people who are not responsible for logging into the server. Focusing on these problems, in this study, Random Port Knocking is the right way and can be used to increase network security. With Random Port Knocking, the port will be opened as needed, the port will automatically change when it fails to log in more than three times and IP will automatically be blocked and access will not continue so that attacks on the network can be avoided and network security stability can be further improved. The final result of this research shows that the method applied in this research makes server safe. Because port randomization and IP block make irresponsible parties try harder to penetrate firewall walls.

In this paper we present results of uniform logical cryptanalysis method applied to cryptographic hash function CubeHash. During the last decade, some of the most popular cryptographic hash functions were broken. Therefore, in 2007, National Institute of Standards and Technology (NIST), announced an international competition for a new Hash Standard called SHA-3. Only 14 candidates passed first two selection rounds and CubeHash is one of them. A great effort is made in their analysis and comparison. Uniform logical cryptanalysis presents an interesting method for this purpose. Universal, adjustable to almost any cryptographic hash function, very fast and reliable, it presents a promising method in the world of cryptanalysis.
