This thesis study presents a high speed VLSI implementation of the Rijndael Encryption Algorithm, which is selected to be the new Advanced Encryption Standard (AES) Algorithm. Both the encryption and the decryption algorithms of Rijndael are implemented as a single ASIC. Although data size is fixed to 128 bits in the AES, our implementation supports all the data sizes of the original Rijndael Algorithm. The core is optimised for both area and speed. Using 149K gates in a 0.35-æm standard CMOS process, 132 MHz worst-case clock speed is achieved yielding 2.41 Gbit/s non-pipelined throughput in both encryption and decryption. iii The design has a latency of 30 clock periods for key expansion that takes 228 ns for this implementation. A single encryption or decryption of a data block requires at most 44 clock periods. The area of the chip is 12.8 mm2 including the pads. 0.35-æm Standard Cell Libraries of the AMI Semiconductor Company are used in the implementation. The literature survey revealed that this implementation is the fastest published non-pipelined implementation for both encryption and decryption algorithms.

FGPA based cryptography computation platform and the basis conversion in composite finite fields
Sial, Muhammad Riaz; Akyıldız, Ersan; Department of Cryptography (2013)
In the study of this thesis work we focused on the hardware based cryptographic algorithms computation platform, especially for elliptic-curve and hyper-elliptic curve based protocols. We worked for making the hyperelliptic curve based Tate Pairing computation efficient specially for hardware implementations. To achieve this one needs to make the underlying finite field arithmetic implementations efficient. For this we study the finite fields of type $\mathbb{F}_q, q=p^{2pn}$ from the efficient implementati...
Design and systemc implementation of a crypto processor for AES and DES algorithms
Egemen, Tufan; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007)
This thesis study presents design and SystemC implementation of a Crypto Processor for Advanced Encryption Standard (AES), Data Encryption Standard (DES) and Triple DES (TDES) algorithms. All of the algorithms are implemented in single architecture instead of using separate architectures for each of the algorithm. There is an Instruction Set Architecture (ISA) implemented for this Crypto Processor and the encryption and decryption of algorithms can be performed by using the proper instructions in the ISA. A...

This thesis explains the implementation of a digital programmable Application Specific Integrated Circuit (ASIC) designed for imaging applications. The primary function of this ASIC is to drive imaging sensors and to do basic processing on the digital video data coming from the sensors. The ASIC is designed to handle the communication between the imaging sensor and the system. Using command based high-level instructions, this two-way communication is simplified. The ASIC can also be used to store and update...
On provable security of some public key encryption schemes
Hanoymak, Turgut; Akyıldız, Ersan; Selçuk, Ali Aydın; Department of Cryptography (2012)
In this thesis, we analyse the security criteria of some public key encryption schemes. In this respect, we present the notion of adversarial goals and adversarial capabilities. We give the definition of provably security by means of several games between the challenger and the adversary in some security models, namely the standard model and the random oracle model. We state the main differences between these two models and observe the advantage of the success probability of the adversary in breaking the cr...
An efficient RSA public key encryption scheme
Aboud, Sattar J.; AL-Fayoumi, Mohammad A.; Al-Fayoumi, Mustafa; Jabbar, Haidar S. (2008-04-09)
In this paper, we propose an efficient RSA public key encryption scheme, which is an improved version of original RSA scheme. The proposed RSA encryption scheme is based on linear group over the ring of integer mod a composite modulus n which is the product of two distinct prime numbers. In the proposed scheme the original message and the encrypted message are h x h square matrices with entities in z(n) indicated via l(h,z(n)). Since the original RSA Scheme is a block cipher in which the original message an...
