This article proposes a provably secure aggregate signcryption scheme for Smart Card. Security of the scheme is based on computational infeasibility of solving Decisional Bilinear Diffie-Hellman Problem and Discrete Logarithm Problems. Confidentiality and authenticity are two fundamental security requirement of Public key Cryptography. These are achieved by encryption scheme and digital signatures respectively. Signcryption scheme is a cryptographic primitive that performs signature and encryption simultaneously in a single logica steps. An aggregate signcryption scheme can be constructed of the aggregation of individual signcryption. The aggregation is done taking n distinct signcryptions on n messages signed by n distinct users.
