Communication between two parties needs security, so this study introduces a protocol called PAKE (password-authenticated key extended exchange), here client segments its password into two equal parts that are stored in 2S (two servers). These 2 servers communicate or coordinate with each other without indicating passwords to each other. Two server-based PAKE protocols on the basis of IBE (Identity-Based Encryption), by using this implicit authentication can be achieved. If any server gets compromised by an adversary, the password of the client has to remain secure. Currently, when compared to Katz et al. EPAKE, two-party PAKE and IBE provable safe without random oracles can save computation in each server. Index Term-PAK, IBE, 2Server, Ant optimization
