Security of AES-128 in Front of Brute Force Attack
Abstract: Advanced Encryption Standard (AES) is one of the best known and most widely used block ciphers. It has three versions, i.e., AES-128, AES-192, and AES-256 that vary in their key sizes 128, 192 and 256 bits and in their number of rounds 10, 12, and 14, respectively. Data security has been a major and challenging aspect in the modern era of information technology involving the internet and network applications. It …

Encryption Mechanism under Prevalent Invasion
Abstract: The digital and computerized era is fast approaching which has increased the amount of data exchanged over the internet. The information transmitted can be accessed by an unauthorized user who can manipulate the data. This fact reveals the need for security mechanisms resulting in various cryptographic algorithms having enhanced protection mechanisms which fulfill the increased demand for security in cyber-attacks and data exploitation. The main goal of these strategies is …

Authentication Scheme using Matrix
Abstract: AbstractThese days, textual passwords are mostly used for authentication. But, these are not much secure because of the problems like brute force attacks, eves dropping, shoulder surfing and guessing. So, there are another authentication schemes to remove these problems, based on session passwords for authentication, and are called color and image authentication schemes. Matrix authentication scheme is based on the session password but with the help of matrix pattern. User …

Design and Implementation of an Improved Cryptographic Algorithm using UNICODE and Universal Colors
Abstract: AbstractA new cryptography algorithm based on Unicode and Universal colors is proposed to preserve the confidentiality of the data. The use of Unicode as encoding scheme provides support to a very large range of characters. The colors are used to obtain a large key domain to avoid cryptanalyst attacks like brute-force and dictionary attacks. The concept is based on the symmetric key cryptography that supports the use of a single …
