Unable to decrypt the webservice content in webMethods 71

Hi,
I am trying to use ws security with webservices in 71. I need to only encrypt the data.
I created a policy file for encryption and assigned the policy to webservice.
Below is my policy file.

<SecurityPolicy xmlns="http://www.webmethods.com/2007/01/policy/security">

	<InboundSecurity>


		<Encryption 
			Usage="Required"
			RequireEncryptedBody="true"/>

	</InboundSecurity>
When I send encrypted data I am receiving following error response. Any help? HTTP/1.1 500 Internal Server Error Content-Length: 1716 Set-Cookie: ssnid=29b408d068ca11ddbdded06f91d3984d; path=/; Content-Type: text/xml <?xml version="1.0" encoding="UTF-8"?>

Resolved the issue by defining public key in the end point alias.
