The need for Authentication in Cloud Computing is to recognize the identity of individuals. The mechanism involves linking an incoming proposal with a set of credentials. Further, verification of credentials with those present on a database containing authentic information takes place. This information is available on a local operating system or verification server. 

The verification process usually runs at the beginning of the system before permitting the user to access and use the codes. Different programs have different practices that involve credential patterns to access any software. The credential is usually in the form of a password. Verification of data happens by the following categories: 

– Information a buyer knows 

– Information relatable to a buyers identity 

– Information a buyer has 

What is the Authentication in Cloud Computing?

The authentication process can be explained in two phases – documentation and proper authentication. The documentation phase provides an identity of the user to the security system for identification. This identity is an official ID that describes the credentials. The security system looks for abstract information that it has and finds specific information for which the user is applying. After completing this, the identification procedure is complete. 

Facts that users claim in this process might not always be authentic. An authentic user is recognizable with the help of an abstract user identifier in the security system. And further rights and permissions are given to the user. The user then provides proof to prove their identity to the security system. The procedure of determining user identity by verifying user-provided proof is called Authentication in Cloud Computing. And the evidence given by the user in this process of authentication is known as a credential.

Ways of Authentication 

  • Verification by password and username 

The vital factor in authentication is to guard data against getting into unauthorized hands. It helps ensure that servers decline visit requests from unidentified people and accept the access of the verified users. In this verification process, the user must enter the correct username and password to log in to the security system and then utilize the data in the cloud. 

  • Trusted Computing Group (TCG) 

The TCG helps measure a set of properties like saving and reporting software and hardware generality by TPM and MTM modules. MTM is a safety factor that works well in mobile phones, and a TPM module is best suitable for PCs. However, in higher protective measures, an MTM can be executed as a little renewed TPM. 

  • Multi-factor authentication (MFA) 

The old authentication process via password may not sufficiently provide data security against the several modern attacks occurring in a cloud computing environment today. A safer process is multi-factor authentication. This method confirms a username/password and also asks for a second verification via biometric authentication. The feasibility of biometric identification is partial due to deployment complications and excessive expenditure. 

  • Single sign-on (SSO) 

SSO is an identity managing system where users are recognized in a single authentication and can then control other resources without repetitive authentication. In other words, verifying information is performed by using diverse programs in this technique. SSO is a procedure by which you can access self-governing multiple software systems. A user can log in and use all systems with no need to log in every time. 

  • Public Key Infrastructure (PKI) 

Traditional authentication systems focus on a hidden key mainly, assisting older asymmetrical encryption algorithms, like RSA. It utilizes private keys to verify a user’s identity. PKI has approvals of forming security protocols like SSL/TSL and mainly uses SET to deliver verification. The success of PKI depends on the control of admission to private keys like other types of encryption security systems. 

  • Biometric verification  

Biometric authentication helps in three points of data security, first authentication, then identification, and last non-repudiation. The literal meaning of biometrics is life measuring. This system is focusing on verifying of physical or behavioral traits of an individual. Plus, it is one of the most impactful verification mechanisms that recognize what we are and what we know. There are two types of Biometric authentication:

  1. Physical biometrics: It is a type of verification that recognizes a user with the help of physical traits. A chief drawback of this biometric system occurs when many individuals require authentication at the same time. It reduces the system speed and efficiency. There are many physical biometric verification methods like hand recognition, fingerprint identification, palm print, voice, face, retinal, and iris scan. Effective use of these methods occurs in Cloud Computing. 
  2. Behavioral biometrics: It helps in identifying the users depending on their position, profile, and similar factors. The two primary kinds of behavioral biometrics are keystroke examination and signature verification.

Authentication in Cloud Computing is crucial and helps keep your data completely safe. It adds value to a system and improves its function. Today many firms prefer authentication and verification to keep their sensitive data protected.
