Let’s talk about security

Message communication between PSPs and UPI are in XML format over HTTPS and
all the messages are digitally signed

Private data in the transaction message are over HTTPS on network, Which are
encrypted before storing in DB

In case of mismatch in the checksum used, the process gets failed & an high level
alert must be generated

IPs for PSPs and other systems are whitelisted at the firewall level in order to block
messages from all non-authenticated sources
