Timing Attacks on Software Implementation of RSA

Creator:: Singh, Harshman
Abstract:: Timing attacks enable an attacker to extract secret information from a cryptosystem by observing timing differences with respect to different inputs given to an encryption or decryption algorithm. Werner Schindler has proposed a timing attack on smart card devices. We implemented this attack based on the same approach for RSA...

Symmetric encryption with multiple keys : techniques and applications

Creator:: Barlow, Lelia C.
Abstract:: Symmetric key block ciphers, such as AES, are well known and frequently used. There are five confidentiality modes of operation that are currently recommended for use with a symmetric key block cipher algorithm: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter (CTR). This...

Some Improved Encoding and Decoding Schemes for Balanced Codes

Creator:: Youn, Jong-Hoon and Bose, Bella
Abstract:: A binary code of length n is called a balanced code if each codeword contains exactly ⌊n/2⌋ (or ⌈n/2⌉) ones and ⌈n/2⌉ (or ⌊n/2⌋) zeros. In this paper, we give two improved methods for encoding and decoding the balanced codes. The first one, called improved single map, improves the computation...

Side channel attack resistant elliptic curves cryptosystem on multi-cores for power efficiency

Creator:: Yoo, Jaewon
Abstract:: The Advent of multi-cores allows programs to be executed much faster than before. Cryptoalgorithms use long-bit words thus parallelizing these operations on multi-cores will achieve significant performance improvement. However, not all long-bit word operations in cryptosystems are suitable for parallel execution on multi-cores. In particular, long-bit words used in Elliptic...

Random number generation on handheld devices for cryptographic applications

Creator:: Montville, Adam W.
Abstract:: Random number generation is important in many fields today. It is particularly important in the field of cryptography when generating nonce values, cryptographic keys, and other data required in many cryptographic applications. The proliferation of small, handheld devices that are typically connected to large networks via a wireless connection requires...

Radix-4 ASIC design of a scalable Montgomery modular multiplier using encoding techniques

Creator:: Tawalbeh, Lo'ai
Abstract:: Modular arithmetic operations (i.e., inversion, multiplication and exponentiation) are used in several cryptography applications, such as decipherment operation of RSA algorithm, Diffie-Hellman key exchange algorithm, elliptic curve cryptography, and the Digital Signature Standard including the Elliptic Curve Digital Signature Algorithm. The most important of these arithmetic operations is the modular...

Optimizing the advanced encryption standard on Intel's SIMD architecture

Creator:: Godbole, Pankaj
Abstract:: The Advanced Encryption Standard (AES) is the new standard for cryptography and has gained wide support as a means to secure digital data. Hence, it is beneficial to develop an implementation of AES that has a high throughput. SIMD technology is very effective in increasing the performance of some cryptographic...

Hardware realization of OCB mode for efficient authenticated encryption

Creator:: Al Faresi, Ahmed
Abstract:: Authenticated-Encryption modes of operation have recently received great atten- tion amongst researchers. Such modes of operation provide both privacy and authentic- ity. A proposed mode in this category is the Offset Codebook mode (OCB) by Rogaway et al. This mode shows great substantial advantages over conventional modes. In the past...
