Abstract In numerous sensor network devices, security is one of the critical issues. A number of symmetric-key encryption algorithms are employed in sensor network hardware and based on standard cryptography, many security algorithms are enhanced for wireless sensor network devices. However, many of these cryptographic algorithms contain own weakness, such as susceptible to selected plaintext attack, password attacks and computational complexity. In WSN, the security of Radio Frequency Identification (RFID) tags contain drawn wide attention from both academia and industry due to the possible wide RFID exploitation and lightweight cryptography in RFID is a significant mechanism in the security information of RFID devices. Therefore, a lightweight cryptographic Multilanguage Two Dimensional Array Substitution Technique (MTDAS) algorithm is presented for RFID tags in this paper to reduce the computational complexity and increase the security during the deployment. This MTDAS algorithm and its low power computational, sizeoptimized accomplishment goals at very embarrassed devicessuch as passive RFID tags. Our proposed algorithm MTDAS gives cryptographic primitivesat very low cost is of dominant significance for protecting applications of RFID. This MTDA Scryptographic algorithm was implemented by using multilingual characters set table. This table is dynamic in nature, and this type of encryption doesn't have any relationship between cipher text and plaintext, so it is difficult for an intruder to get back the plaintext.
