  Introduction

1 ybrid encryption is a mode o$ encryption t)at merges t,o or moreencryption systems. It incorporates a combination o$ asymmetric

and symmetric encryption to bene+t $rom t)e strengt)s o$ eac) $orm

o$ encryption. )ese strengt)s are respecti*ely de+ned as speed andsecurity.

2. ybrid encryption is considered a )ig)ly secure type o$ encryptionas long as t)e public and pri*ate eys are $ully secure.

3.ybrid encryption is ac)ie*ed t)roug) data trans$er using uni!uesession eys along ,it) symmetrical encryption. ublic eyencryption is implemented $or random symmetric ey encryption.
