CA是认证/维护证书，RA是签发证书

RA系统负责对用户的申请资料进行审核以决定是否，CA只对RA通过审核的用户颁发证书。

crl  也需要ra收集信息，由ca完成签发\r\n\r\nra收集信息，并将信息发送给ca，ca完成证书颁发

CA主要负责证书授权、取消。管理功能全部由RA来完成，实际操作。没有决定的权利

The PKI element that manages the certificate life cycle, including certificate directory maintenance and certificate revocation list (CRL) maintenance and publication is the:\r\n\r\n        A. certificate authority.\r\n        B. digital certificate.\r\n        C. certification practice statement.\r\n        D. registration authority.\r\n\r\n        The correct answer is:\r\n        A. certificate authority.\r\n\r\n       Explanation:\r\n        The registration authority manages the certificate life cycle, including certificate directory maintenance and certificate revocation list (CRL) maintenance and publication. The certificate authority attests, as a trusted provider of the public/private key pairs, to the authenticity of the owner to whom a public/private key pair has been given. The digital certificate is composed of a public key together with identifying information about the owner of the public key. It associates a public key with an individual\'s identity. Certificates are e-documents digitally signed by a trusted entity containing information on individuals. The process entails the sender digitally signing a document with the digital certificate attached issued by a trusted entity where the receiver relies on the public key that is included in the digital certificate to authenticate the message. The certification practice statement is the governance process for CA operations.\r\n\r\n答案和解释有矛盾啊，按解释应该是RA，另外一个题目又是CA ，糊涂。

Which of the following manages the digital certificate life cycle to ensure adequate security and controls exist in digital signature applications related to e-commerce?\r\nA. Registration authority\r\nB. Certificate authority\r\nC. Certification relocation list\r\nD. Certification practice statement\r\n\r\nThe correct answer is:\r\nB. Certificate authority\r\n\r\nYou answered correctly.\r\n\r\nExplanation:\r\nThe certificate authority (CA) maintains a directory of digital certificates for the reference of those receiving them. It manages the certificate life cycle, including certificate directory maintenance and certificate revocation list maintenance and publication. Choice A is not correct because a registration authority is an optional entity that is responsible for the administrative tasks associated with registering the end entity that is the subject of the certificate issued by the CA. Choice C is incorrect since a CRL is an instrument for checking the continued validity of the certificates for which the CA has responsibility. Choice D is incorrect because a certification practice statement is a detailed set of rules governing the certificate authority\'s operations.
