Cryptography And Embedded Systems Used

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

The article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the

During this time Richard has showed himself as a promising young specialist and researcher. His major specialization is Applied Mathematics and Computer Science, but as an exception for academic achievements, Alex was allowed by our faculty to write his projects and degree thesis in the field of Cryptography under Computer Security and Applied Algebra Department.

            In the past decade, rapid advances have been made in the field of cryptography.  These advances have brought considerable

Due to emerging technologies such as big data, cloud platform and use of internet in day to day activities has led to security concerns for various end users. The transfer and storage of information is a crucial part in many business processes, industrial activities and also in military regime. The information could be in forms such as text data, video, audio, image or e-mail. Cryptography is a method to ensure the security and privacy of data transfer process. Data acquisition is the process of acquiring data accurately with minimum loss of signal being acquired and storing it for further use. Data acquisition and information protection is important in military applications. In the paper, a secure data acquisition system for military application is designed. The FPGA platform is used for implementation of the system design.

Security at hardware level is a new trend in security industry; it will accelerate the security at the processor and chip-set level (Vaquero, Rodero-Merino and Moran, 2011:112). Antivirus solution with Computers and Hardware will eliminate antivirus and Firewall security solutions industry. (Bruce Schneier accessed January/9 2013). Intel is planning to move computer security to the hardware level from its current software level, by incorporating security features onto their chips and processors (MEED 2010).This will also hit the IT Security devices market.

The privacy preserving techniques also have data sanitization, cryptography techniques and access control techniques. The data sanitization techniques refer as a process, which conceals sensitive information in their data sets. Here in this method implements various techniques to offer the privacy to their dataset. The access control methods are implemented to reduce and handle the access to the host system and their applications through communication links. The cryptography techniques are implemented to offer a tough security and privacy and also offer exact and practical implementation. The cryptography protocols permits secure communications through addressing their authentication [1].

High level encryption or cryptography is used in a number of applications ranging from those which impact national security to those which are more mundane. Essentially, cryptography is the methodology of encoding information so that one’s privacy is ensured. This is particularly important when it comes to transactions which occur over the Internet. The risk of individuals gaining access to personal information or information which is critical to a country or a nation over the Internet is a very real one. The practice of cryptography lessens the likelihood of this happening.

After reading this chapter and completing the exercises, you should understand the following about cryptography.

Data encryption is the key role in current and future technologies. Many public key cryptography algorithms were presented depending on a specific mathematical problem. It is desired to communicate data with high security over insecure network. Due to sensor technology biometrics has lead to rising concerns about the network security, privacy, trust issues and accuracy. Hence, securing biometric template in public network is great challenge. Because once it is compromised or stolen it cannot be revoked. In order to provide remote biometric authentication these systems incorporated with cryptography and primarily focused on template security, revocability, privacy, accuracy. The system is secure in the sense that the biometric are going to

Lately, hardware security has been the subject of intensive research in the context of general-purpose computing and communications systems. However, security is often misunderstood by embedded system designers to be an add-on luxury that can otherwise be done away with in order to improve efficiency and certain other aspects of their product designs such as the cost, performance, power consumption and similar metrics. In reality, security needs to be incorporated as a new dimension by the system designers and it needs to be a primary objective of such design considerations right from the initial stages of the product lifecycle due to its high relevance and intrinsic value in subsequent stages of its operation. The challenges

This topic deals more about the methods and technologies in tandem for en-hancing overall security of any embedded device . At places one can notice that the topics discussed earlier could have criss-crossed here, but here the same discussion is more looked from the prism of overall security rather than arbitrarily which was the case earlier.

We will provide a brief Description to Elliptic Curve Cryptography and the implementation of new attacks on the cryptography in this section. If you want to a comprehensive description about to ECC than you can find it in [10],[11]. A reader want to go through a summary of power analysis attacks, by far the class of implementation attacks, we refer you to [8].

Almost in every field including banking and insurance security and privacy have become the essence. Many people prefer internet banking because of its convenience. The solution to the security issues require the use of cryptography in which data is being encrypted and converted to cipher text and then decrypted to original form on reaching the second party. It is an indispensable tool for secured communication between two parties in the presence of third party. This article attempts to introduce the various algorithms which can be successfully used to ensure the security in banks. These algorithms include Shift algorithm, Polyalphabetic Cipher, Affine Cipher, RSA, DSA etc.

An individual has many personal email accounts and hence he needs to remember their passwords. Remembering all the credit card numbers is a heavy duty [6]. ELockBox can encrypt one’s file containing all the ID’s, passwords etc. and store it on the server instead of storing it on the phone itself. For Encrypting and Decrypting the file AES algorithm is used. AES algorithm can be implemented with 128, 192 and 256 bits[1]. AES algorithm is efficient to protect classified information which is on SECRET level. For TOP SECRET 192 and 256 bit key AES is recommended. AES algorithm is the main part in the eLockBox. The passwords required for authentication of a person and file is stored on the server rather than in one’s phone. In the authentication process, a person is required to prove his identity using Login ID’s or draw patter (CAPTCHA) or both for better security. After successfully entering into eLockBox a person can encrypt his file and then upload it on the server. A person is required to remember the secret key that is generated automatically while the process of encryption. This key
