Query: Software implementation level countermeasures against the cache timing
  attack on advanced encryption standard   Advanced Encryption Standard (AES) is a symmetric key encryption algorithm
which is extensively used in secure electronic data transmission. When
introduced, although it was tested and declared as secure, in 2005, a
researcher named Bernstein claimed that it is vulnerable to side channel
attacks. The cache-based timing attack is the type of side channel attack
demonstrated by Bernstein, which uses the timing variation in cache hits and
misses. This kind of attacks can be prevented by masking the actual timing
information from the attacker. Such masking can be performed by altering the
original AES software implementation while preserving its semantics. This paper
presents possible software implementation level countermeasures against
Bernstein's cache timing attack. Two simple software based countermeasures
based on the concept of "constant-encryption-time" were demonstrated against
the remote cache timing attack with positive outcomes, in which we establish a
secured environment for the AES encryption.
