“…The modules of steganography security are different for cloud system and general systems, especially in distributed computing. The main feature of the steganography model is that it is possible to make the model work under various sites of the distributed system [8]. For cloud computing, the attacks on steganography operation relate to side channel attacks.…”

Storing data in a third party cloud system causes serious problems on data confidentiality. Generally, encryption techniques provide data confidentiality but with limited functionality, which occurs due to unsupported actions of encryption operation in cloud storage space. Hence, developing a decentralized secure storage system with multiple support functions like encryption, encoding, and forwarding tends to get complicated, when the storage system spreads. This paper aims mainly on hiding image information using specialized steganographic image authentication (SSIA) algorithm in clustered cloud systems. The SSIA algorithm is applied to virtual elastic clusters in a public cloud platform. Here, the SSIA algorithm embeds the image information using blowfish algorithm and genetic operators. Initially, the blowfish symmetric block encryption is applied over the image and then the genetic operator is applied to re-encrypt the image information. The proposed algorithm provides an improved security than conventional blowfish algorithm in a clustered cloud system. ARTICLE HISTORY

“…Due to advancement of communication technologies, exponential number of users are connecting to the cloud servers through light weight resource constrained devices like mobile phone, tab etc. As discussed in [1], the presence of powerful and resourceful machines as cloud servers and a set of resource constrained devices like mobiles, tab etc as terminal devices makes the cloud computing system as asymmetric computing and demands for light-weight cryptography which provides strong security features and minimized processing needs at the terminal side operations.…”

“…Many researchers [13][14][15][16]19] have analyzed that cryptographic and steganographic operations requires huge computational resources and best suitable for resource full server side. In Nimmy et al [9] scheme the resource constrained client side devices are overloaded with huge cryptographic and steganographic operations which makes the scheme impossible to adopt to cloud scenario [1]. As a part of our contribution, we will propose an improved mutual authentication scheme which is light weight on both client and server sides, and resistant to all major cryptographic attacks.…”

Cloud computing is a collection of virtually massive distributed large scale computers to handle enormous enterprise computing, hardware, storage needs. An exponential advancement of communication and information technologies results in substantial traffic for accessing of cloud resources wired and mobile, through various communication devices like desktop, laptop, tabs, etc. via Internet. Significance of enterprise data and increased access rates from low-resource terminal devices demands for reliable and low cost authentication techniques. Lots of researchers have proposed authentication schemes based on password, biometric, steganography etc. with varied efficiencies. In 2014, Nimmy et al proposed a steganography based mutual authentication protocol for cloud computing and claimed that their scheme resists major cryptographic attacks.Unfortunately, in this paper we will show that Nimmy et al is vulnerable to offline password guessing attack and Denial of Service attack. As a part of our contribution, we propose a low cost steganography based authentication scheme which is strongly secure and best suited for asymmetric cloud computing environment.
