Strain Sensor and Accelerometer Communication Channels in Drill Pipes of Oil Wells: Delay Spreads and Eigenvalues

Many symmetric encryption algorithms have been proposed since long time back. They are used to protect the data either during transmission, storage or both. All symmetric algorithms are using a single key used for encryption and decryption same data. In this paper, we have designed a new approach of symmetric algorithm "UR8". It is fiestel network and able to encrypt and decrypt 128 bits block cipher. Further, UR8 algorithm uses 64 bits key size and 8 rounds to encrypt and decrypt the data. Thereafter, we have evaluated UR8 algorithm based on the time required for encryption and decryption, throughput, memory utilization and average data rate. As well, the evaluation result has been compared to DES algorithm.
