Question: Discuss about the Performance Analysis of Crypto System. Answer: Introduction: The process of conversion of a plain text data to an unreadable version of data by the use of standard algorithm is known as encryption. Encryption is generally used for protecting the sensitive information from the access of unauthorized persons (Biham Shamir, 2012).. The process of encryption is common in WiMax in order to encrypt and protect all the traffic it experiences in its network. Out of many different encryption standards management, the most commonly used encryption standards in WiMax networks includes triple DES, AES or advanced encryption standard and CCMP or Counter Mode Cipher Block Chaining Message Authentication Protocol. These three encryption standards are elaborated further in the following table- Triple DES AES CCMP Triple DES or 3DES is a symmetric key algorithm protocol that uses three keys of 56-bit length for ensuring a high level of encryption. 3DES uses a symmetric block cipher and implements the basic DES algorithm three times to ensure extra protection. However, the running of the algorithm three times results in the process becoming slower and therefore the performance of DES is much slower in comparison to other encryption standards and algorithm. 3DES has a fixed key size and therefore it becomes easier to implement this encryption standard. The 3DES technology uses or based on ANSIX9.52 standard 3DES is one of the most widely used encryption standard for WiMax network. 3DES led to the evolution of a more advance encryption standard, which is known as triple AES or advanced encryption standard (Singh, 2013). Advanced encryption standard or AES is a better and more secure encryption standard for WiMax network It uses different encryption keys of 128 bit, 192 bit or 256 bit as standard encryption keys. AES is a symmetric block cipher algorithm (Karthik Muruganandam, 2014) After 3DES, AES is the most commonly used encryption standard for WiMax protocol (Daemen Rijmen, 2013.). It however requires a dedicated processor for implementation of AES in WiMax network. CCMP or counter mode cipher block chaining message authentication is an encryption standard generally developed for wireless LAN. It uses 128-bit key for protecting the access of data (Saberi et al., 2012). It is a block cipher mode encryption standard. CCMP is based on AES or advanced encryption standard. Offers enhanced security as it employs 128bit keys and a 48-bit initialization vector. Wireless personal area network is a network of interconnecting devices, which enables connection of wireless connection to the different devices. WPAN technology is generally used for setting up short range communication and helps in setting up a low power consumption in a very low cost. It is beneficial and is used for setting up small personal networks. The example of two such WPAN technologies is Bluetooth and ZigBee. Bluetooth is a standard for short-range wireless interconnection of mobile phones and other electronic devices management. ZigBee is however more simple than Bluetooth and is less expensive. The cost of installation and the cost of data transfer are very low. There are however, certain security concerns that are associated with the WPAN technologies that are discussed in the following paragraphs- The different threats that are associated with the Bluetooth technology includes blue bugging, bluejacking and bluesnarfing. In these attacks, the hacker or the attacker gets an unauthorized access to the network. This may lead to the information leakage and installation of malicious contents into the network (Minar Tarique, 2012). ZigBee is a very simple network infrastructure and therefore, an attacker can easily gain physical access to the data and encryption key of the devices, leading to the disclosure of the confidential information and data. Furthermore, the node of a ZigBee can be readily imitated that may lead to the hacker gaining access to the physical network (Zillner Strobl, 2015). The process of gathering energy from external, natural or manmade resources is known as energy harvesting. The different external sources of energy includes harvesting of solar, wind, radio frequency energy and so on. Wireless sensor networks face a lot of energy problems as it requires a continuous supply of energy to perform the functions properly (Shaikh Zeadally, 2016). The wireless sensor networks has increasing popularity due to its pervasive nature and its use in internet of things. The different energy harvesting techniques can help in acquiring continuous energy supply to the nodes of wireless sensor networks, which will help in ascertaining a promising future in the field of wireless sensor networks management. The problems associated with Wireless sensor networks are mainly due to the use the continuous loss of current from the battery power due to current leakages and battery breakdown. Therefore, the battery as an energy source is to be replaced in order to ascertain th e normal working of the sensor nodes. Energy harvesting helps the wireless sensor nodes in acquiring continuous supply of energy, which in turn helps in reducing the use of conventional energy (Ulukus et al., 2015). The different energy harvesting techniques that can be implemented for eliminating the related energy problems associated with the harvesting of energy is elaborated below (Shaikh Zeadally, 2016)- Energy harvesting using radio frequency is one of the modern energy harvesting techniques that can be used for conversion of radio waves to DC power energy. This helps in eliminating the energy issues associated with the wireless sensor technologies. Solar energy harvesting is another efficient energy harvesting techniques, where the solar energy is used to yield electrical energy, which may help in impending the energy problems associated with the wireless sensor networks. Thermal energy is another important energy harvesting techniques that converts the heat energy to electrical energy. The energy of the wind can be harvested for generation of electricity that can be used for eliminating the energy problems associated with the wireless sensor networks. In hydro energy harvesting techniques, the energy of flowing water is harvested to convert that energy into electrical energy. In flow based energy harvesting techniques, the energy of turbines and rotors are used for converting its rotational energy to electrical energy. References Biham, E., Shamir, A.
