Essay On Cryptographic Primitives

We can say that the weakness of the keys and the process of incorrect use, as well as erroneous implementation cannot be considered as a unique case because it represents a common risk for each encryption algorithms [21].

Security in the age of internet has become a tremendously important issue to provide comfort not only for paranoid people but for many others who are naïve to believe that protection in digital era is essential to communication between millions of people that increasingly used as a tool for commerce.

Cryptococcosis is a chronic mycotic infection caused by Cryptococcus neoformans variation neoformans and Cryptococcus neoformans var. gattii, both considered opportunistic. Though the organism is usually harmless to humans, the yeast type fungus can severely affect those with severe immunosuppression, such as HIV and AIDS patients.

Wallets accounts for 8% of the total personal apparel and accessories market. The US market for the items is currently served by about 470 businesses with operations across the country but with concentration in Florida, New York, Loss Angeles and Texas. The market was faced economic challenges that resulted to its decline in 2008 to 2009 during the great recession. However, the market is currently recovering and has registered a 1.2% growth from the year 2009 to 2013. Further,

After reviewing Riordan’s current security system, it is suggested that more stringent security and restricted access should be imposed upon users and employees throughout the company. Those with proper authorization may be permitted to access the required data to perform their daily duties, whereas others without proper authorization require approval to access the requested data. With tighter restrictions and limited access of data and information, these practices will strengthen security considerably. Currently, Riordan does not have in place an online ordering system or official contact methods with customers.

In today’s computer based world there are several potential and devastating threats like hackers, viruses, worms, and Trojans etc. to our computers, networks, and confidential information. So as to protect any computers, networks, and confidential information the installation of security applications is vital and hardware systems to protect our confidential information, computers, and networks. Some of the most popular Internet security systems are firewalls, intrusive prevention system, intrusive detection system, access control, and cryptographic tools and processes. However, there is no Internet security application or

If you want to keep information secret, you have two possible strategies: hide the existence of the information, or make the information unintelligible. Cryptography is the art and science of keeping information secure from unintended audiences, of encrypting it. Conversely, cryptanalysis is the art and science of breaking encoded data. The branch of mathematics encompassing both cryptography and cryptanalysis is cryptology.

Security is one of the significant problems in the current technological world. Although there are many inherent confidential securities are provided to the developing and developed softwares, managing the risks determined by security breaches still remains a conundrum. The prime objective of this paper is to discuss the elemental security concepts and techniques which have to be applied during the each phase of software development cycle to build a secured code. Also, this paper confers about the strategies and metrics which can be used to determine on how the security threats are mitigated and managed and the best practices to acheive security coding assurance. To match the prospective potential needs of secured code, threats associated with the information security and all favourable circumstances of risks have to be bounded by security i.e., it must be ‘baked-in’ with the entire lifecycle of system or software development.

Cloud Services have become more popular as they provide a lot of advantages like high speed processing ,Flexibility and Disaster recovery.The problem is Security of data and how to ensure that data being processed at the cloud is secure

There has been a need for a non-breakable encryption algorithm desired after since the establishment of Cryptography was first matured. However, an algorithm is advised to be immune as long as there has not been found susceptibility through cryptanalysis. Symmetric-key block ciphers abide as the largest and critical aspect in many cryptographic systems. Independently, they add confidentiality. As a central construction block, their adaptability grants the manufacturing of pseudorandom stream ciphers, number generators, hash functions, and MAC’s. Moreover they serve as an essential component in message verification methods, symmetric-key signature schemes, entity confirmation protocols, and data purity. Although Block ciphers are very powerful objects their design flaws and complex interface opens the door for wider attacks.

Since the beginning of civilization, humans have needed a way to communicate in secret. Whether it be a letter to a lover or a set of orders for an army, it would be paramount for these messages to arrive unknown and untouched. However at some point, a person could easily apprehend the message; perhaps a spy or the letter bearer, nevertheless the chance of the message being compromised would be quite high. Thus one would have to change the message to appear as meaningless nonsense to those others than the intended recipient. This idea formed the basis of cryptography, the backbone of digital security.

Cryptography is a science that transforms information into secure form by providing basic protections. These protections include confidentiality, Integrity, Availability, Authentication, and Nonrepudiation (Ciampa 189). Let’s understand the characteristics of information and their description (see table 1).

Electronics and nanotechnology working together would yield a holistic solution to data storage problems that are encountered with conventional techniques. This paper aims at familiarizing the reader about some of the available and emerging data storage technologies which are direct consequences of advancement of

Deniable ring signature: The ring signature scheme which has the property of anonymity revocation is known as deniable ring signatures. This was first proposed by Susilo and Nu . In this ring signature scheme, the verifier can interact with the signer or entities to confirm that the signer or entity has signed the signature with zero knowledge interactive proof. In this signature scheme, any signer cannot shift blame to other entities. Denial ring authentication is a combination of ring signatures and deniable authentication. Digital signatures provides authentication of messages thus providing non-repudiation of messages. In most of the applications, non-repudiation is one of the desirable properties, but in some applications it may not be. Inspired by such requirements Naor introduced Deniable ring signature scheme in 2002. In such ring authentication scheme, the verifier can be convinced that a entity of an adhoc group of participants is authenticating a message m, by not disclosing the identity information of the signer entity. It is also not possible for the verifier to convince any third party entity that message m is authenticated. This has been found in a number of applications. The Deniable ring signature scheme has the following properties:

Now-a-days security plays a vital role in eletronics world.The speed and area optimization is an important issue in today’s electronics.The AES is a cryptographic algorithm that is used to protect electronic data or information. AES algorithm is a symmetric key used in that can encrypt and decrypt
