¶ … weaknesses of the Data Encryption Standard (DES).
The Data Encryption Standard (DES) was a system developed by the USD government for use by the general public. Accepted both by the U.S. And abroad, many hardware and software systems employ the DES. Both individuals can send and encrypt and decrypt information to and from the other. The symmetry of the situation makes this a popular key. Authenticity is guaranteed since only the sender can produce a message that will encrypt with the shared key (Paar, & Pelzl, 2009). However the DES is also riddled by various weaknesses (Pfleeger & Pfleeger, 2007).
Firstly and, perhaps, most importantly, security is a major concern. Whilst issues have been more or less resolved regarding the design's secrecy and that certain 'trapdoors' had been embedded in the DES algorithm enabling easy means to decrypt the message, many analysts are still concerned about the number of iterations considering 16 iterations to be insufficient in diffusing the information. Most serious of all, however,...
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
In this manner, it makes network management and filtering a lot easier. Even though SPF can protect the network infrastructure against certain attacks that are known to exploit the weaknesses that are inherent in the various network level protocols, it can never provide protection at application level. The application defense needs more awareness of the content of the payload. Circuit Proxy Firewall (CPF) This type of firewall operates by relying as
