We propose pretty simple password-authenticated key-exchange protocol which is based on the difficulty of solving DDH problem. It has the following advantages: (1) Both y1 and y2 in our protocol are independent and thus they can be pre-computed and can be sent independently. This speeds up the protocol. (2) Clients and servers can use almost the same algorithm. This reduces the implementation costs without accepting replay attacks and abuse of entities as oracles.
