问题描述
我正在试图找出如何使用Cassandra与TDE(透明数据加密),并在其中支持DataStax版本TDE。我一直在去通过DataStax文档,从我看到,TDE仅在DataStax企业版中受支持。这是否正确?
此外,TDE包含在表/列级别,并在创建新表时指定,而不是某些配置?
只是想确认我的假设。
提前感谢
您的假设是正确的。
透明数据加密仅在DataStax Enterprise中支持(自3.2版本起) / p>
透明数据加密在创建/更改表时指定
ALTER TABLE users WITH compression = {
'sstable_compression':'Encryptor',
'cipher_algorithm':'AES / ECB / PKCS5Padding',
'secret_key_strength' 128,
'chunk_length_kb':1
};
包含有关透明度的最新文档DSE 4.7中的数据加密
I'm trying to figure out how to use Cassandra with TDE (Transparent Data Encryption) and in which DataStax edition TDE is supported.
I've been going through DataStax documentation and from what I see, TDE is supported only in DataStax Enterprise Edition. Is this correct?
Also, TDE is included on table/column level and is specified when creating new tables, not as some configuration?
Just want to confirm my assumptions.
Thanks in advance
Your assumptions are correct.
Transparent Data Encryption is only supported in DataStax Enterprise (since version 3.2).
Transparent Data Encryption is specified when you create/alter a table
ALTER TABLE users WITH compression = {
'sstable_compression' : 'Encryptor',
'cipher_algorithm' : 'AES/ECB/PKCS5Padding',
'secret_key_strength' : 128,
'chunk_length_kb' : 1
};
http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/sec/secTDEtblcrypt.html contains the latest documentation about Transparent Data Encryption in DSE 4.7
