LEOPARD lightweight encryption operation permutation addition rotation and diffusion

Tactical unmanned vehicles are commonly used to conduct tasks (e.g. monitor and surveillance) in various civilian applications from a remote location. The characteristics of the wireless communication link allows attackers to monitor and manipulate the operation of the unmanned vehicle through passive and active attacks. Cryptography is selected as a countermeasure to mitigate these threats; however, a drawback of using cryptography is the impact on the energy consumed by the unmanned vehicle as energy is often constrained and limits the duration of the mission time. This paper introduces the Lightweight Encryption Operation Permutation Addition Rotation and Diffusion (LEOPARD) cryptographic primitive with a benchmark performance analysis against the standardised Advanced Encryption Standard (AES). Results indicate that LEOPARD is a feasible encryption approach in comparison to the AES encryption algorithm for unmanned vehicles with an average performance increase of 8%

A Quantitative Study of Advanced Encryption Standard Performance as it Relates to Cryptographic Attack Feasibility

The advanced encryption standard (AES) is the premier symmetric key cryptosystem in use today. Given its prevalence, the security provided by AES is of utmost importance. Technology is advancing at an incredible rate, in both capability and popularity, much faster than its rate of advancement in the late 1990s when AES was selected as the replacement standard for DES. Although the literature surrounding AES is robust, most studies fall into either theoretical or practical yet infeasible. This research takes the unique approach drawn from the performance field and dual nature of AES performance. It uses benchmarks to assess the performance potential of computer systems for both general purpose and AES. Since general performance information is readily available, the ratio may be used as a predictor for AES performance and consequently attack potential. The design involved distributing USB drives to facilitators containing a bootable Linux operating system and the benchmark instruments. Upon boot, these devices conducted the benchmarks, gathered system specifications, and submitted them to a server for regression analysis. Although it is likely to be many years in the future, the results of this study may help better predict when attacks against AES key lengths will become feasible

Optimizing the performance of the advanced encryption standard techniques for secured data transmission

Information security has emerged as a critical concern in data communications. The use of cryptographic methods is one approach for ensuring data security. A cryptography implementation often consists of complex algorithms that are used to secure the data. Several security techniques, including the Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), Twofish, Rivest-Shamir-Adleman (RSA), Elliptic curve cryptography, and many others, have been created and are used in the data encryption process. However, the Advanced Encryption Standard (Rijndael) has received a lot of attention recently due to its effectiveness and level of security. To increase the scope of AES's numerous uses, it is crucial to develop high-performance AES. To enhance the processing time of AES methods, the research provided solution performance of the AES algorithm. This includes additional layers of encoding, decoding, shrinking and expansion techniques of the analysis that was performed. Data findings are produced for further actions based on the outcome

Comparative Analysis of Some Efficient Data Security Methods among Cryptographic Techniques for Cloud Data Security

The concept of cloud computing model is to grant users access to outsource data from the cloud server without them having to worry about aspects of the hardware and software management. The owner of the data encrypts it before outsourcing to a Cloud Service Provider (CSP) server for effective deployment of sensitive data. Data confidentiality is a demanding task of cloud data protection. Thus, to solve this problem, lots of techniques are needed to defend the shared data. We focus on cryptography to secure the data while transmitting in the network. We deployed Advanced Encryption Standard (AES) used as encryption method for cloud data security, to encrypt the sensitive data which is to be transmitted from sender to receiver in the network and to decrypt so that the receiver can view the original data. Arrays of encryption systems are being deployed in the world of Information Systems by various organizations.

A novel block cipher design paradigm for secured communication

Unmanned aerial vehicles (UAV) are commonly used to conduct tasks (e.g. monitor and surveillance) in various civilian applications from a remote location. Wireless communications (i.e. radio frequency) are often used to remotely pilot the UAV and stream data back to the operator. The characteristics of the wireless communication channel allows attackers to monitor and manipulate the operation of the UAV through passive and active attacks. Cryptography is selected as a countermeasure to mitigate these threats; however, a drawback of using cryptography is the impact on the real-time operation and performance of the UAV.

Secure and Energy-Efficient Processors

Security has become an essential part of digital information storage and processing. Both high-end and low-end applications, such as data centers and Internet of Things (IoT), rely on robust security to ensure proper operation. Encryption of information is the primary means for enabling security. Among all encryption standards, Advanced Encryption Standard (AES) is a widely adopted cryptographic algorithm, due to its simplicity and high security. Although encryption standards in general are extremely difficult to break mathematically, they are vulnerable to so-called side channel attacks, which exploit electrical signatures of operating chips, such as power trace or magnetic field radiation, to crack the encryption. Differential Power Analysis (DPA) attack is a representative and powerful side-channel attack method, which has demonstrated high effectiveness in cracking secure chips. This dissertation explores circuits and architectures that offer protection against DPA attacks in high-performance security applications and in low-end IoT applications. The effectiveness of the proposed technologies is evaluated. First, a 128-bit Advanced Encryption Standard (AES) core for high-performance security applications is designed, fabricated and evaluated in a 65nm CMOS technology. A novel charge-recovery logic family, called Bridge Boost Logic (BBL), is introduced in this design to achieve switching-independent energy dissipation and provide intrinsic high resistance against DPA attacks. Based on measurements, the AES core achieves a throughput of 16.90Gbps and power consumption of 98mW, exhibiting 720x higher DPA resistance and 30% lower power than a conventional CMOS counterpart implemented on the same die and operated at the same clock frequency. Second, an AES core designed for low-cost and energy-efficient IoT security applications is designed and fabricated in a 65nm CMOS technology. A novel Dual-Rail Flush Logic (DRFL) with switching-independent power profile is used to yield intrinsic resistance against DPA attacks with minimum area and energy consumption. Measurement results show that this 0.048mm2 core achieves energy consumption as low as 1.25pJ/bit, while providing at least 2604x higher DPA resistance over its conventional CMOS counterpart on the same die, marking the smallest, most energy-efficient and most secure full-datapath AES core published to date.PHDElectrical EngineeringUniversity of Michigan, Horace H.
