¶ … Security and Cryptographic Algorithms Well before the advent of readily available digital computing technology, the ability to craft encrypted messages through the use of complex codes and ciphers, was highly prized by the governmental apparatus and the private sector alike. From the codes messages passed furtively throughout the courts of medieval Europe, to the infamous Enigma cipher machine which protected Nazi secrets in World War II, the concept of cryptography is nearly as old as the written word itself. Today, the field of information technology has developed to the point that even the most sophisticated encryption methods are vulnerable, and for those working as information security officers, shielding a company's invaluable data through the use of encryption has become an essential skill. Modern encryption methods rely on much of the same techniques used throughout history, with human readable plaintext being...
Within the sub-field of cryptanalysis a growing focus on mathematical theory has spawned the development of intricately constructed algorithms, or governing systems used to precisely define a sequence of operations (Layton, 2007). Modern cryptographic algorithms are capable of creating computationally secured systems that, while they can be theoretically deciphered, are ostensibly secure from any feasible attack strategy. The most widely applied cryptographic algorithms employed by information security officers today typically…
Internet Encryption The growing sophistication of internet, along with advancing abilities of individuals to hack into electronic systems is creating a growing need for improved encryption technology. The internet is becoming a domain all to itself, with its own rules, and requirements. The internet is creating new opportunities for the business and communication industries. It is also creating new demands. The internet is now facing a period in its evolution similar
Bluetooth devices use encryption security and this makes the requirement of a "unique key session key to derive per-packet keys thus avoiding frequent key reuse." (Kennedy and Hunt, 2008, p.4) Kennedy and Hunt report that ZigBee is a reasonably priced low energy consumption two-way CDMA/BA-based wireless communications standard which is based on IEEE 802.15.4 which is referred to commonly as a 'Low Rate Wireless Personal Area Networks (LR-WPANs) and which
General Packet Radio Services (GPRS) is a service used in the provision of packet radio access for the GSM (for Global System for Mobile Communications) users [1].In regard to the wireless component, the GPRS technology makes a reservation of the radio resources only in instances when there are instances of data to be sent over its infrastructure. This therefore ensures that the radio resources are optimized. The fixed part
Digital signatures are comprised of a series of algorithms and mathematical constructs that ensure the authenticity and verifiability of a person signing a specific document. The reliance on digital signatures continues to increase as virtual work teams, the development of automated contract management, compliance, financial reporting and advanced workflows in the fields of financial services continues to grow (Keenan, 2005). The intent of this analysis is to define the properties
Encryption With the ever-increasing amount of information traffic on the net (LAN, WAN, etc.) there is a corresponding increase in the risk of vital data falling into the wrong hands. Data encryption is a technology that provides for a safe, secure and private information exchange. The advancement of computer technology has bought a paradigm shift to our mode of communication. The Internet has managed to overcome all the geographical limitations and
Executive Summary The purpose of this study is to develop timely and informed answers to a series of guiding research questions and subquestions to identify the risks and barriers that are associated with Internet of Things implementations. These types of studies are important today because the Internet of Things is changing the manner in which companies of all sizes and types operate their businesses, and current trends indicate that these implementations
