As far as I know non pairing pairing based cryptography is less time consuming than pairing based because, pairing based uses complex operations. Are there any advantages of pairing based cryptography over elliptic curves without using pairing based cryptography?

If you can express your operation well using plain groups, go with normal elliptic curves. But the pairing adds additional mathematical structure, which enables new algorithms.

Some examples:

  • BLS signatures

    They're verifiably deterministic and small, 2x security level, instead of 3 to 4 times, with DSA/Schnorr/ElGamal signatures.

    These use the pairing as a decisional Diffie-Hellman oracle.

  • Identity based encryption using the Boneh–Franklin scheme.

  • $\begingroup$ @Nubila I just posted two schemes that require pairings, what more do you want? $\endgroup$ – CodesInChaos Jun 22 '15 at 8:01
  • $\begingroup$ I am doing my mtech projct. It is the security of data sharing in cloud. For this I would like to use cerificateless cryptography.the base paper is implemented as without using pairing . so I want to modify it to with pairing scheme. So i want to know that which have any advantage.. $\endgroup$ – Nubila Jun 22 '15 at 8:14

  • $\begingroup$ @Nubila You didn't even link the paper you're talking about. You didn't give enough context. Your question isn't answerable like that. $\endgroup$ – CodesInChaos Jun 22 '15 at 8:20
