Slow Initial Database Connection

Question

I think I have a slowness issue with the initial Oracle database connection. When I try to connect initially, the connection , it takes a long time. Is there anyway to speed this up...
I am using encryption and jdbc on oracle.
This takes a good 20 - 30 seconds....
Class.forName("oracle.jdbc.driver.OracleDriver");
PARAMETERS.put("oracle.net.encryption_client","REQUIRED");
PARAMETERS.put("oracle.net.encryption_types_client","DES40C");
PARAMETERS.put("oracle.net.crypto_checksum_client","REQUESTE");
PARAMETERS.put("oracle.net.crypto_checksum_types_client","MD5");
PARAMETERS.put("user",user);
PARAMETERS.put("password",password);
connect = DriverManager.getConnection(dbUrl,PARAMETERS);

Answer 1

Didn't I answer this question?
The process of encrypting the connection, and generating MD5 checksums for each message sent over that connection both take considerable time to set up and the only way to make it go faster is to throw more processing power at it (i.e., get a faster computer), or switch to a far weaker form of encryption (but that means we can break the code in mere minutes).
This is a known feature. This is why the National Security Agency (NSA) and the National Reconniassance Office (NRO) have more supercomputers than any other US Government Agency.
If time really is a factor, then I suggest that you drop the MD5 requirement. MD5 essentially confirms that you have received all of the data you are expecting (and in a particular order) and no more than that. Attempting to decrypt DES also confirms that you have received all of the data you wanted (in the correct order) and no more than that. In other words, the two functions are redundant.
However, MD5 is a one way function whereas DES is two way; DES allows you to decrypt the message itself, but MD5 only allows you to confirm that the message is genuine. Hence, drop MD5 in favor of DES.
If you're really interested in rewriting the DES and MD5 schemes for more speed, do some reading on the cryptography forums, or check out an appropriate book at the library.
