Secured Wireless Communication using Fuzzy Logic based High Speed Public-Key Cryptography (FLHSPKC)

摘要

In this paper secured wireless communication using fuzzy logic based highspeed public key cryptography (FLHSPKC) has been proposed by satisfying themajor issues likes computational safety, power management and restricted usageof memory in wireless communication. Wireless Sensor Network (WSN) has severalmajor constraints likes inadequate source of energy, restricted computationalpotentiality and limited memory. Though conventional Elliptic CurveCryptography (ECC) which is a sort of public key cryptography used in wirelesscommunication provides equivalent level of security like other existing publickey algorithm using smaller parameters than other but this traditional ECC doesnot take care of all these major limitations in WSN. In conventional ECCconsider Elliptic curve point p, an arbitrary integer k and modulus m, ECCcarry out scalar multiplication kP mod m, which takes about 80% of keycomputation time on WSN. In this paper proposed FLHSPKC scheme provides somenovel strategy including novel soft computing based strategy to speed up scalarmultiplication in conventional ECC and which in turn takes shortercomputational time and also satisfies power consumption restraint, limitedusage of memory without hampering the security level. Performance analysis ofthe different strategies under FLHSPKC scheme and comparison study withexisting conventional ECC methods has been done.
