Network security is an important aspect of information sharing. Attempts have been made to
remove various insecurities over internet. For this, many technological implementations and …

In recent years, a variety of encryption algorithms were proposed to enhance the security of
software and systems. Validating whether encryption algorithms are correctly implemented …

In this paper we have proposed a technique for securing biometric traits using the modified
Hill Cipher with an involutory key and a robust cryptosystem. The Modified Hill Cipher solves …

Biometric is uses to identify authorized person based on specific physiological or behavioral
features. Template protection is a crucial requirement when designing an authentication …

Exchange of secure information between the sender and receiver draws the attention of
several researchers due to its importance in various fields ranging from national security …

Hill cipher needs inverse of the key-matrix for decryption. To avoid inversion, involutory
matrices can be used. Known Hill cipher variants with involutory matrices have memory and …

Data security is the science and study of methods of protecting data in computer and
