摘要： A secure signing method, a secure authentication method, and an IPTV system are disclosed. The secure signing method includes preparing digital signature header fields and setting an attribute, calculating a hash digest of content using a hashing algorithm, storing the calculated hash value in a message digest field of the digital signature header, encrypting the message digest using a secret key and inserting the encrypted message digest in a signature field of the digital signature header, and associating the digital signature header with the content by prefixing the digital signature header to the content. The secure authentication method includes checking whether a format and value of a digital signature header of content are appropriate, calculating a hash digest of the content using a hashing algorithm, comparing the calculated hash value with a message digest field of the digital signature header, decrypting the hash value of the signature field of the digital signature header using a public key extracted from a certificate field, and comparing the decrypted hash value with the message digest.
