As we all are aware that internet acts as a depository to store cyberspace data and provide as a service to its user. cloud computing is a technology by internet, where a large amount of data being pooled by different users is stored. The data being stored comes from various organizations, individuals, and communities etc. Thus, security and privacy of data is of utmost importance to all of its users regardless of the nature of the data being stored. In this research paper the use of multiple encryption technique outlines the importance of data security and privacy protection. Also, what nature of attacks and issues might arise that may corrupt the data; therefore, it is essential to apply effective encryption methods to increase data security.

In today's world web applications have become an instant means for information broadcasting. At present, man has become so dependent on web applications that everything done through electronic means like e-banking, e-shopping, online payment of bills etc. Due to an unauthorized admittance might threat customer's or user's confidentiality, integrity and authority. SQL injection considered as most Spartan dangerous coercions to the databases of web applications. current scenario databases are highly susceptible to SQL Injection[4] . SQL Injection is one of the most popular and dangerous hacking or cracking technique . In this work authors projected a novel approach to mitigate SQL Injection Attacks in a database. We have illustrated a technique or method prevent SQLIA by incorporating a hybrid encryption in form of Advanced Encryption Standard (AES) and Elliptical Curve Cryptography (ECC) [5]. In this research paper integrated approach of encryption method is followed to prevent the databases of the web applications against SQL Injection Attack. Incidentally if an invader gains access to the database, then it can cause severe damage and ends up with retrieves data or information. So to prevent these type of attacks a combined approach is projected , Advanced Encryption Standard (AES) at login phase to prevent the unauthorized access to databases and on the other hand Elliptical Curve Cryptography (ECC) to encode the database so that without the key no one can access the database information [3]. This research paper illustrates the technique to prevent SQL Injection Attack.

The problem statement is that at present there is no stable algorithm which provides security for resource constrained devices because classic cryptography algorithms are too heavy to be implemented. So we will provide a model about the various cryptographic algorithms in this field which can be modified to be implement on constrained devices. The advantages and disadvantages of IOT devices will be taken into consideration to develop a model. Mainly IOT devices works on three layers which are physical layer, application and commutation layer. We have discuss how IOT devices individually works on these layers and how security is compromised. So, we can build a model where minimum intervention of third party is involved i.e. hackers and we can have higher and tight privacy and security system [1].we will discuss about the different ciphers(block and stream) and functions(hash algorithms) through which we can achieve cryptographic algorithms which can be implemented on resource constrained devices. Cost, safety and productivity are the three parameters which determines the ratio for block cipher. Mostly programmers are forced to choose between these two; either cost and safety, safety and productivity, cost and productivity. The main challenge is to optimize or balance between these three factors which is extremely a difficult task to perform. In this paper we will try to build a model which will optimize these three factors and will enhance the security of IOT devices.

Cryptographic protocols and algorithms are the strength of digital era in which we are living. Unluckily, the security of many confidential information and credentials has been compromised due to ignorance of required security services. As a result, various attacks have been introduced by talented attackers and many security issues like as financial loss, violations of personal privacy, and security threats to democracy. This research paper provides the secure design and architecture of cryptographic protocols and expedites the authentication of cryptographic system. Designing and developing a secure cryptographic system is like a game in which designer or developer tries to maintain the security while attacker tries to penetrate the security features to perform successful attack.

Now a days, ATM is used for money transaction for the convenience of the user by providing round the clock 24*7 services in financial transaction. Bank provides the Debit or Credit card to its user along with particular PIN number (which is only known by the Bank and User). Sometimes, user's card may be stolen by someone and this person can access all confidential information as Credit card number, Card holder name, Expiry date and CVV number through which he/she can complete fake transaction. In this paper, we introduced the biometric encryption of "EYE RETINA" to enhance the security over the wireless and unreliable network as internet. In this method user can authorizeasthird person his/her behalf to make the transaction using Debit or Credit card. In proposed method, third person can also perform financial transaction by providing his/her eye retina for the authorization & identification purpose.
