Increasing the key length is one way to increase security of an encryption algorithm against the brute-force type of attack. DES uses 56-bit key, which is not secure, given the modern computing power. Assume that 56-bit key was just sufficient in 1979 when DES was standardized, and assume that the hardware performance improves about 100% (i.e., doubles) every two years, then how many bits of a DES key would just suffice in the year 2048?
