摘要
签密是一种将数字签名和加密结合的技术,在移动电子商务等场合有很好的应用前景,目前基于身份的签密方案的研究一直是一个难点。针对这种情况,提出了一个新的利用双线性对构建的基于身份的签密方案,此方案将身份信息引入签名密钥,并将消息融入签名信息,而且签名的验证和消息的恢复可以分别独立进行。方案可以应用于为移动设备过滤垃圾信息等移动电子商务场合。
Signcryption combines digital signature and encryption, but the research about the efficient Identity based signcryption schemes is difficuh. For this, an efficient ID-based signcryption scheme which uses bilinear pairings is proposed. In the scheme, identity message is imported into signature key, and signature contains message. As the scheme can separate the signature verification from message recovery, it can be applied in mobile E-business scenario, such as filtration of bad instant messages of mobile equipment.
