摘　　要：随着电子政务和电子商务的发展,电子印章得到了广泛的应用,为了保证电子印章文件的安全。因此根据相关的密码学原理,提出了基于ECC和SHA-1的电子印章文件校验方案及实现。使用安全散列函数SHA-1获取电子印章文件的数字摘要,并依据椭圆曲线签名原理,对数字摘要进行数字签名,同时,使用高级加密算法AES对电子印章文件和数字签名进行加密。实现了电子印章文件不可否认、不可伪造及保证完整性。With the development of e-Government and e-commerce, e-seal is widely applied for ensuring the security of e-seal documents. Based on the principle of related cryptography an e-seal documents check and implementation scheme based on ECC and SHA-1 is proposed, and with SHA-1 hash function for acquiring the digital digest of an electronic document, and by implementing digital signature in accordance with the principle of elliptic curve signature, and at the same time, with the advanced encryption algorithm AES for encrypting e-seal documents and digital signature, the non-deniability, non-forgery and integrity of e-seal documents are thus realized and ensured.
