【 摘 要 】

Due to their complexity, computation time and power requirement, the secure and widely used cryptographic systems such as 3DES and AES may not be considered suitable for applications like mobile and remote sensing of sensitive data. Therefore, secure but less complicated algorithms for data encryption are still sought. This paper suggests a new Segmented Block Cipher Algorithm (SBCA) is a symmetric algorithm that relies on simple mathematical operations and permutation processes on segmented message blocks. The ASCII code representations of the message characters and the key contents are dealt with throughout the encryption and decryption phases. Obtained results manifested a reasonable computation time while the checked security strength looks.
