An efficient variant of RSA cryptosystem was proposed by Cesar [2]. He called it Rprime RSA. The Rprime RSA is a combination of Mprime RSA [3] and Rebalanced RSA [9, 1]. Although the decryption speed of Rprime RSA is 27 times faster than the standard RSA and 8 times faster than the QC RSA [6] in theoretically, yet due to the large encryption exponent, the encryption process becomes slower than ...

Based on the Chinese Remainder Theorem (CRT), Quisquater and Couvreur proposed an RSA variant, RSA-CRT, to speedup RSA decryption. According to RSA-CRT, Wiener suggested another RSA variant, Rebalanced RSA-CRT, to further speedup RSA-CRT decryption by shifting decryption cost to encryption cost. However, such an approach will make RSA encryption very time-consuming because the public exponent e...

Modern mobile phones are increasingly being used for more services that require modern security mechanisms such as the public-key cryptosystem RSA. It is, however, well-known that public-key cryptography demands considerable computing resources and that RSA encryption is much faster than RSA decryption. It is consequently an interesting question if RSA as a whole can be executed efficiently on ...

background: human peripheral blood nk cells constitutively express cd56 and cd16 antigens. peripheral blood nk cells seem to be strongly related with decidual nk cells, and may reflect the decidual nk cell functional status. there are varied reports concerning the relationship between nk cell cytotoxicity in women with recurrent spontaneous abortion. objective: to study nk activity in women wit...

there are several known and unknown factors for unexplained recurrent spontaneous abortion (ursa). among them, complement regulatory protein cd46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. we aimed in this study to investigate the possible association of cd46 ivs1-1724 c>g polymorphism with rsa in iranian women. 141 women w...

Boneh and Shacham gave a nice survey on four variants (Batch RSA, MultiPrime RSA, MultiPower RSA, Rebalanced RSA). Rebalanced RSA and MultiPower RSA were then combined to increase the decryption/signature generation performance. This combination theoretically improves the decryption/signature generation time about 14 times than RSA with CRT and about 56 times than the standard RSA with key size...

Objectives. No data regarding phenotypic assets of circulating lymphocytes in antiphospholipid syndrome (APS) are reported in the literature. Role of anti-phospholipid antibodies (aPL) in recurrent spontaneous abortion (RSA) remains uncertain, while natural killer (NK)-cells are involved in RSA pathogenesis. In this study, patients affected with APS without RSA, APS with RSA and RSA without aPL...

To investigate the role of the 'male factor' in the pathogenesis of recurrent spontaneous abortion (RSA), especially sperm morphology abnormalities, 120 previously selected couples with unexplained RSA were studied for sperm parameters retrospectively and prospectively. The patients were subdivided into three subgroups, depending on their reproductive outcome during the 3 years of follow-up stu...

In 1982, Quisquater & Couvreur proposed a variant of RSA based on the Chinese Remainder Theorem, called RSA-CRT, to speed up RSA decryption. In 1990, Wiener suggested another variant, called Rebalanced RSA-CRT, which further speeds up RSA decryption by shifting decryption costs to encryption costs. However, this approach essentially maximizes the encryption time since the public exponent e in R...

Cryptographic techniques in cyber security can be categorized into symmetric and asymmetric. Among asymmetric cryptographic techniques, the RSA algorithm is more popular considered as secured. Since, uses common modulus both encryption decryption, this openly available for public which makes it exposed attack. Its based on assumption of large integer factorization problem, but could leave open ...
