In order to improve the security and efficiency performance of wireless sensor network signature-encryption

on the basis of identity-based signature（IBS） with the bilinear pairings on elliptic curves

an attribute-based encryption combined with identity-based signature （ABE-IBS） scheme was proposed

besides

one efficient signature-encryption scheme for WSN was also discussed. Analysis and experimental results show that proposed scheme has the low complexity and storage requirement

and can enhance the security of wireless sensor network.
