-The high growth in the cloud computing has reached the each and every corners of the world. The cloud computing offers the dynamically shared resources namely networks, storage, servers, services and applications, without physically acquiring them. So it saves managing cost and time for organizations. Cloud services providers various services like SaaS, Paas, IaaS, NaaS and etc., over the internet. Cloud Computing moves the application software and databases to the large data centers, where the management of the data and services may not be fully trustworthy. This unique attribute, however, poses many new security challenges which have not been well understood. Security is to save data from danger and vulnerability. There are so many dangers and vulnerabilities to be handled. There are still some challenges to be solved among that the security and trust issues are vital one. In this paper the various kinds of the encryption algorithms are discussed in details and the performances of those algorithms are evaluated to analysis the best algorithm for the cloud platform. This discusses the various open research issues and challenges that present in the cloud platform.

“…Switched capacitor [13] is able to isolate the encryption core from the external power supplies, but this approach results in 50% speed loss for replenishing charge every cycle. In order to avoid the throughput degradation, a countermeasure circuit using digital controlled ring oscillators [14] is designed outside of the critical path. The concept is to generate random noise power to dominate the power consumption of arithmetic unit, and then the correlation peak would not be found even matching the correct key value.…”

Abstract. Correlation power-analysis (CPA) attacks are a serious threat for cryptographic device because the key can be disclosed from data-dependent power consumption. Hiding power consumption of encryption circuit can increase the security against CPA attacks, but it results in a large overhead for cost, speed, and energy dissipation. Masking processed data such as randomized scalar or primary base point on elliptic curve is another approach to prevent CPA attacks. However, these methods requiring pre-computed data are not suitable for hardware implementation of real-time applications. In this paper, a new CPA countermeasure performing all field operations in a randomized Montgomery domain is proposed to eliminate the correlation between target and reference power traces. After implemented in 90-nm CMOS process, our protected 521-bit dual-field elliptic curve cryptographic (DF-ECC) processor can perform one elliptic curve scalar multiplication (ECSM) in 4.57ms over GF (p 521 ) and 2.77ms over GF (2 409 ) with 3.6% area and 3.8% power overhead. Experiments from an FPGA evaluation board demonstrate that the private key of unprotected device will be revealed within 10 3 power traces, whereas the same attacks on our proposal cannot successfully extract the key value even after 10 6 measurements.

IndexTerms-Side-channel attack, Reconfigurable architecture, Cryptographic Coprocessor, correlation based differential analysis (CPA), electromagnetic analysis (EMA).Abstract-A secure reconfigurable cryptographic co-processor (SRCP) supporting multiple algorithms of AES, DES, RC6 and IDEA is proposed using its own reconfigurable feature to resist Side-channel attack (SCA). It is integrated into a system-on chip and fabricated in 0.18 μm CMOS process with 1.8 V supply voltage and 100 MHz max frequency. Several kinds of specific countermeasures are proposed to hide leakage information by utilizing idle reconfigurable processing elements (PEs) to do dummy operations. Its advantages lie in its little impact on area and frequency as well as high flexibility after silicon that countermeasures can also be reconfigured. Furthermore, different protections including several kinds of global countermeasures and encryption flow related countermeasures can be stacked, thus the security level can be tuned by trading for some performance or power consumption. Experimental SCA attack results show that it resists SPA and DPA without revealing the subkey. For correlation based EMA of DES configuration, it increases 36× measure to disclosure when applied with partial countermeasures compared to unprotected DES. As to AES configuration with full countermeasures, it resists EMA with no sign to reveal the right subkey for up to 1.2 million electromagnetic traces.
