SSL(Secure Socket Layer) is currently the most widely deployed security protocol, and consists of many security algorithms, but it has some problems on processing time and security. This paper proposes an HSEP(Highly Secure Electronic Payment) Protocol that provides better security and processing time than an existing SSL protocol. As HSEP consists of just F2mHECC, ThreeB(Block Byte Bit Cipher), SHA algorithm, and Multiple Signature, this protocol reduces handshaking process by concatenating two proposed F2mHECC public key and ThreeB symmetric key algorithm and improves processing time and security. In particular, Multiple signature and ThreeB algorithm provides better confidentiality than those used by SSL through three process of random block exchange, byte-exchange key and bit-xor key.
