文摘Authentication is the most crucial aspect of security and a predominant measure employed in cybersecurity.Cloud computing provides a shared electronic device resource for users via the internet,and the authentication techniques used must protect data from attacks.Previous approaches failed to resolve the challenge of making passwords secure,memorable,usable,and time-saving.Graphical Password(GP)is still not widely utilized in reality because consumers suffer from multiple login stages.This paper proposes an Indexed Choice-Based Graphical Password(ICGP)scheme for improving the authentication part.ICGP consists of two stages:registration and authentication.At the registration stage,the user registers his/her data user name a number called Index Number(IN),and chooses an image from a grid of images.After completing the registration,ICGP gives the user a random unique number(UNo)to be a user ID.At the authentication stage,the user chooses a different image from the grid based on the random appearance of the registered image dimensions on the grid plus the registered Index Number.ICGP password is a combination of three factors;user’s name,UNo,and any image.According to the experiments,the proposed ICGP has achieved great improvements when compared to prior methods.The ICGP has increased the possible password numbers from 9.77e+6 to 3.74e+30,the password space from 1.20e+34 to 1.37e+84,and decreased the password entropy from 7.16e−7 to 8.26e−30.
