Certificate-less (CL) signature schemes were presented to deal with key escrow issue in ID based signature. In recent years a number of digital signatures schemes with bilinear pairing have been presented to maintain information security and integrity. Acutely, the greater part of them endure intent security invasion. They don’t enforce in terms of computing and dissemination complications. Many researchers have proposed different schemes on anonymity for multi receiver identity based cryptography. In this paper an attempt has been made to propose an efficient CL Digital Multi-Receiver (CL-DMS) scheme with anonymity without bilinear pairing which is secure against foregeability, key replacement and key escrow attack. Our motivation is to design a CL DMS that simulcast a message with high level of computation efficiency and employs security that only proficient recipients can fetch the message. This will also include the non-repudiation as well as the time replay attack. We presented an enhanced and efficient scheme, which is secure against Type 1, and Type II attacks. We also compare the proposed scheme with some existing schemes in terms of computation and communication cost with higher level of security.

具有匿名性的高效多接收者无证书数字多重签名方案

提出了无证书（CL）签名方案来处理基于ID的签名中的密钥托管问题。近年来，提出了许多具有双线性配对的数字签名方案，以保持信息的安全性和完整性。急性地，它们中的很大一部分会经受故意的安全入侵。它们不会在计算和传播复杂性方面强制执行。许多研究人员针对基于多接收者身份的密码学提出了关于匿名性的不同方案。本文尝试提出一种有效的CL数字多接收器（CL-DMS）方案，该方案具有匿名性而无需双线性配对，可以防止可预知性，密钥替换和密钥托管攻击。我们的动机是设计一种CL DMS，它以高计算效率同时广播消息，并采用只有熟练的收件人才能获取消息的安全性。这还将包括不可否认性以及时间重播攻击。我们提出了一种增强而高效的方案，该方案可抵御1型和II型攻击。在计算和通信成本较高的安全性方面，我们还将提出的方案与现有方案进行了比较。
