With the rapid development of MANET, the secure and practical authentication problem in it increasingly becomes outstanding. The existing work study the problem from two aspects, i.e. secure key division/distributed storage and secure distributed authentication. But existing cheating problems and fault attack possibility will break the security. Besides, efficiency performance of such schemes is not good enough due to the exponential arithmetic with Shamir's scheme. Due to these problems above, we explore the property of verifiable secret sharing(VSS) schemes with Chinese Remainder Theorem(CRT). Then a secret key distributed storage scheme based on CRT-VSS and trusted computing is proposed for MANET. We utilize trusted computing technology to solve two existing cheating problems in secret sharing area before. After that we do some analysis of the homomorphism property with CRT-VSS scheme. Compared with the secure shares-product sharing scheme based on Shamir's scheme, we design the corresponding scheme base on CRT-VSS scheme with better concision and equal security later. On such basis, a distributed Elliptic Curve-Digital Signature Standard signature (ECC-DSS) authentication scheme based on CRT-VSS scheme and trusted computing is proposed. The choice of the trusted authentication node can eliminates the possibility of traditional DoS and fault attack. At last, we do some security analysis towards our schemes proposed above.
