Wall of Sound but Phil came along and took these to make sounds that had not been used in the past. I thought it was ingenious." During the mid-1950s, Spector worked with Brill Building songwriters Jerry Leiber and Mike Stoller during a period where they sought a fuller sound by the use of excessive instrumentation, using up to five electric guitars and four percussionists. This was later to evolve into Spector's Wall of Sound, which Leiber and Stoller consider to be very distinct from what they were doing, stating: "Phil was the first one to use multiple drum kits, three pianos and so
Pairing-based cryptography to an element from a second group. Some researchers classify pairing instantiations into three (or more) basic types: If symmetric, pairings can be used to reduce a hard problem in one group to a different, usually easier problem in another group. For example, in groups equipped with a bilinear mapping such as the Weil pairing or Tate pairing, generalizations of the computational Diffie–Hellman problem are believed to be infeasible while the simpler decisional Diffie–Hellman problem can be easily solved using the pairing function. The first group is sometimes referred to as a Gap Group because of the assumed difference in
