Final answer:
Triple DES is almost three times faster than DES.
Step-by-step explanation:
The statement is True. Triple DES (Data Encryption Standard) is an encryption algorithm that applies the DES encryption algorithm three times to each data block. It provides a higher level of security compared to DES but with a trade-off in terms of speed.
DES operates on 64-bit data blocks and applies 16 rounds of operations to encrypt or decrypt a block. Triple DES, on the other hand, applies three rounds of DES encryption, using two or three different keys.
While Triple DES provides stronger security, it requires more computational resources, making it slower than DES. However, advancements in hardware and optimizations have reduced the performance gap, making Triple DES almost three times faster than DES in some cases.
