EMV联系人卡发行者公钥验证

Question

I have problem with validation of EMV contact card issuer public key. Document says: "Verify that the concatenation of RID, Certification Authority Public Key Index, and Certificate Serial Number is valid. If not, SDA has failed." I concatenated these and sending them to SHA1 function to gain a hash value that will be compared with the public key's hash value and i took a comparision error; because their values are not equal. Did I misunderstand the document?

Answer 1

Wich document do you refer?

Normaly you would get a CDOL in the GPO Response. The data for SDA should concatenated as described in this CDOL.

Remark: You should use DDA at minimum as supported.
