Abstract:

Data security will play a central role in the design of future IT systems. The PC has been a major driver of the digital economy. Recently, there has been a shift towards IT applications realized as embedded systems, because they have proved to be good solutions for many applications, especially those which require data processing in real time. Examples include security for wireless phones, wireless computing, pay-TV, and copy protection schemes for audio/video consumer products and digital cinemas. Most of these embedded applications will be wireless, which makes the communication channel vul

Abstract:

Ad hoc networks are standalone networks supporting "communication anytime and anywhere" using portable devices like PDAs, cell phones, laptops etc. which require no predefined organization of available links but offer constraints such as battery life, bandwidth, memory, computational ability, security, quality of service, reliability, range of the device and speed. Security framework is essential and relies on certificates to communicate with each other but requires higher battery life, bandwidth and memory space. Researchers have been using keys as an alternative. However, no protocol is comp

Il bisogno dell'uomo di nascondere e protegge le informazioni risale ad epoca antica; infatti, la crittografia ha avuto un ruolo molto importante in diversi momenti storici, basta pensare al cifrario di Cesare o alla macchina Enigma e la macchina di Lorenz durante la Seconda guerra mondiale, e questi sono solo alcuni esempi tra i più conosciuti. Per tanto, possiamo dire quindi che la crittografia rappresenta un vasto ambito di applicazione e al giorno d'oggi, con il rapido sviluppo della tecnologia, risulta essenziale per garantici sicurezza e privacy in quanto quest'ultima è stata minuta.

Elliptic curves were first proposed as a basis for public key cryptography in the mid 1980's. They provide public key cryptosystems based on the difficulty of the elliptic curve discrete logarithm problem (ECDLP) , which is so called because of its similarity to the discrete logarithm problem (DLP) over the integers modulo a large prime. One benefit of elliptic curve cryptosystems (ECCs) is that they can use a much shorter key length than other public key cryptosystems to provide an equivalent level of security.

Security issues have started to play an important role in the wireless communication and computer networks due to the migration of commerce practices to the electronic medium. The deployment of security procedures requires the implementation of cryptographic algorithms.

However, the complicated computation over the finite field required in ECC is quite a challenging task. Consequently, it is critical for us to figure out how to accelerate the computation speed.

Elliptic curve cryptosystem (ECC) employs shorter key than RSA cryptosystem, for example, ECC with 160-bit key has same security level as RSA with 1024-bit key. Thus, ECC is suitable for smart mobile devices on mobile commerce. Finite field multiplication in GF(2m) is very important in elliptic curve cryptosystem, because multiplication can be used for carrying out other complicated finite field mathematics such as multiplication inversion,

Abstract:

碩士<br>南華大學<br>資訊管理學系碩士班<br>99<br>Recently, many non-interactive deniable authentication (NIDA) protocols have been proposed. They are mainly composed of two types, signature-based and shared-secrecy based. After reviewing these schemes, we found that the signature-based approach can not deny the source of the message and thus can not achieve full deniability; and that, the shared-secrecy based approach suffers KCI attack although it can achieve full deniability. In addition, both types of schemes lack efficiency consideration for they mainly base on DLP, factoring, or bilinear pairing. Due to

With this development, our life has become more and more convenient. However, IoT devices bring some information security and power consumption issues. Elliptic curve cryptosystem (ECC) and RSA cryptosystem are the classic representatives of public key cryptosystem (asymmetric cryptosystem). Especially ECC is a very popular research field in recent years, because its key length is much smaller than that of RSA when the same security is achieved. As a r

Opposite to RSA, the Elliptic Curve Cryptosystem (ECC) attracts more and more attention. In 1985, Koblitz and Miller proposed a higher security public key cryptosystem, based on ECDLP, called ECC. At present, there are several international standards proposed in ISO 11770-3, ANSI X9.62, IEEE P1363, FIPS 186-2. The advantages of ECC are that its key sizes are smaller than RS

碩士<br>國立臺北科技大學<br>電機工程系所<br>99<br>Various studies had pointed out that a 160-bit elliptic curve cryptosystem provides the same level of safety as 1024-bit RSA cryptography. It means that the elliptic curve cryptography works with a short key length. Owing to this merit, the elliptic curve cryptography is suitable for mobile device with its small chip area. Scalar multiplication plays the key role of core calculations in the elliptic curve cryptosystem. In this thesis the proposed architecture uses the parallel processing method to accelerate its operating speed. In short, this thesis continued

Since the idea of threshold verification is initialed in recent years, it increasingly attracts many researchers’ attentions. In the thesis, these two ideas are integrated into a specified-verifier group-oriented threshold signature scheme. In the proposal, no matter the generation and verification of signature, a threshold value is used in qualifying the number of participants inste
