A Key-Scheduled Block Cipher Using element-wise Linear Transformation and Logical XOR Operation

Cryptography is a key technology in electronic security systems. Modern cryptographic techniques have many uses, such as to digitally sign documents, for access control, to implement electronic money, and for copyright protection. The increased use of computer and communication systems by industry has increased the risk of theft of proprietary information. In general, cryptographic primitives are designed to satisfy particular security objectives which may be built from the four basic objectives – confidentiality, data integrity, authentication and non-repudiation. In the present paper a new key-scheduled block cipher is proposed using element-wise Linear Transform and logical XOR operation.
