highlighted. Finally, a comparison of the two protocols will be conducted to justify the selection of a preferred security protocol verification. Strand Space Protocol Strand space protocol is a framework model for designing and verification of cryptographic protocols. It is considered to be a local behavior of a single session of a particular protocol. The strand space model operates on two additions for a fair

Introduction In this coursework, the main aim is to compare two network security software tools using Kali Linux to carry out a type of attack which helps build and develop an awareness to protect computers from varies password attacks. The chosen software tools are offline password attack (John the Ripper) and (RainbowCrack) which they both are from similar Cyber Security attacks under password cracking tools. John the Ripper is free on multi-platform as it combines various password cracking features in

E and so on (Ciampa 186). This method of changing the original text into a secret message is called encryption and retrieving back to the original form is called decryption. The clear plaintext is given as input to the cryptographic algorithm. According to Stallings cryptographic algorithms consists of mathematical functions which are used to encrypt and decrypt the data (44). A key is a mathematical value which

Overview: Hashing in terms of encryption is the conversion of a word into a usually fixed-length value or key that represents the original word. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It basically uses a hash function to convert the word into the key. Hash function is one that is used to map data of random size to data of fixed size. Values that are returned from a hash

and cheaper since the bitcoin is not tied to any government or any rule and regulation. Since there is no intrinsic value to the Bitcoin, vast amounts of research has gone into the security of its protocol. The original focus of attacks were known as History-Revision attacks, a concept conceived in the creation of Bitcoin. Yet, research has revealed its infeasibility; it can be shown that, mathematically, the probability that a ‘dishonest’ --or fake-- chain is longer than an ‘honest’ one grows exponentially

Running Head: Cryptography 1 Cryptography 12 Applied Cryptography Rough Draft ISSC 431 Professor Christopher Weppler October 6, 2015 Introduction Over the years, cryptography has been used to protect secrets, in a military capacity to make sure that either hackers, enemies of the countries, do not intercept sensitive formation. Ciphers, and encryption blocks are becoming so hard to break even the best super computers cannot break the codes in a timely fashion. Encryption

firmware verification as stated by 3.1.1 Checksum Algorithms To ensure that data sent over a communications channel is error free on arrival, a non-cryptographic checksum algorithm is typically used [1]. These algorithms are generally effective at detecting noise but cannot reliably detect changes by malicious parties. An example of non-cryptographic checksum

Introduction The MD6 hash algorithm with the full name of the Message Digest Algorithm 6 is a cryptographic hash algorithm developed at MIT by a team led by Professor Ronald L. Rivest in response to the call for proposals for a SHA-3 cryptographic hash algorithm by the National Institute of Standards and Technology. MD6 is the latest of the “message digest” algorithm

one numerical character (0-9). 4. Password should contain atleast one special character. (!,.?@#%$^)(*&^+=). Passwords should not be dictionary words as it makes dictionary attacks easier. Passwords also should not contain personal information like first name, last name, date of birth, pets name, etc. as it makes brute force attack easier. Also, multiple sites should not have the same password. [3] If the user forgets the password, in only some applications it can be

transmission, and sharing of a huge amount of images, songs, and videos much easier and faster Cryptographic hash functions used to map the input data to a binary strings, different digital representations can emerge from an image through image processing like rotation, cropping, compression, filtering etc…, the change of one bit of the original data results in a radically different sequence [1][2]. The cryptographic hash functions are not appropriate for image authentication as they are sensitive to every
