“…Generally, authentication protocols may be classified into three main groups [88]: (1) based on symmetric cryptosystems; (2) based on asymmetric cryptosystems; and (3) hybrid. The majority of those utilize hash functions as their basis, thus allowing to combine the secret information "shares" into one specific secret key.…”

Presently, smart and connected wearable systems, such as on-body sensors and head-mounted displays, as well as other small form factor but powerful personal computers are rapidly pervading all areas of our life. Motivated by the opportunities that next-generation wearable intelligence is expected to provide, the goal of this work is to build a comprehensive understanding around some of the user-centric security and trust aspects of the emerging wearable and close-to-body wireless systems operating in mass events and under heterogeneous conditions. The paper thus intends to bring the attention of the research community to this emerging paradigm and discuss the pressing security and connectivity challenges within a popular consumer context. Our selected target scenario is that of a sports match, where wearable-equipped users may receive their preferred data over various radio access protocols. We also propose an authentication framework that allows for delivery of the desired content securely within the considered ecosystem.

“…As is described in [2], having a larger key means more security due to the encrypted information will be more resistant to a brute force attack. However, computing a larger key also means more time, energy and resource consumption, which could lead to a lost in performance [3]. This fact makes asymmetric key algorithms have a stronger security level with a lower performance |104 Ingeniería y Ciencia in comparison with symmetric key algorithms, which demonstrated in [1].…”

One of the main disadvantages of symmetric key algorithms in compar-ison with asymmetric key ones is their lower security level due to theirshorter key length. Indeed, increasing the number of bits that conformsthe key used by a symmetric cryptography algorithm will increase its se-curity level with a cost on its performance. Expanding a key in symmetriccryptography is not an easy task due to algorithms are designed to workwith keys of a fixed maximum length. This paper presents an alterna-tive design of the RC5 cryptography algorithm with an enhanced securitylevel achieved through a key expansion mechanism with Parallel Comput-ing processing. Although the design was created for the RC5 algorithmthe main idea might be applied to other block cipher algorithms applyingthe same criteria. This methodology makes feasible to obtain a robustsymmetric key algorithm implemented in software with an acceptable per-formance in comparison with other techniques such as implementations inhardware, reduction in the amount of data, improvements in the key ex-change process, advanced high performance computing, and many otherstechniques

“…Thus, we can use the important advantages of these two algorithms such as the convenience and security of RSA secret key management, and AES high speed encryption [15] [16]. Additionally, we have execute HMAC function using the secret key and produced cipher text to attach the produced value at the end of encrypted message in order to send them to cloud server to insure the integrity and authenticity of message [17].…”

The technology of Cloud computing is permit the subscribers to store their own data in its infrastructure. The subscribers will be able to use their stored data whenever they required. Since the data are stored outside their boundary, it needs to use a strong encryption during transmission process to be protected well. Thus, in this paper we have proposed a model to use a hybrid encryption and decryption process based on AES-128 and RSA algorithm. Furthermore, we used HMAC algorithm to ensure the integrity and authenticity of data. Our experiment work has been done to explain the time required, throughput and memory utilization for encryption and decryption based on different size of files. KeywordsAdvanced Encryption Standard (AES-128), RSA, hash based message authentication code (HMAC).
