Sam wants a simple security solution that does not require each customer to have an individual key for his e-commerce site. Encryption is a process of encoding information in such a way that only authorized parties can access it.
There are two main types of encryption methods:
If Sam uses Symmetric encryption for his e-commerce site, then he would need to share the same key with all customers, which could be a security risk. Therefore, Symmetric encryption is not a suitable option for Sam's requirement.
If Sam uses Asymmetric encryption, he can provide the public key to all customers, and only he will have the private key. This means that customers can send their sensitive data securely, and Sam can decrypt it using his private key. Therefore, Asymmetric encryption is a suitable option for Sam's requirement.
S/MIME: S/MIME (Secure/Multipurpose Internet Mail Extensions) is a protocol for securing email messages using encryption and digital signatures. It provides authentication, confidentiality, and message integrity. While S/MIME can be used for e-commerce sites, it is mainly designed for securing email communications.
PGP: PGP (Pretty Good Privacy) is a data encryption and decryption program used for email encryption and file encryption. It uses both symmetric and asymmetric encryption methods. While PGP can be used for e-commerce sites, it is mainly designed for securing email communications.
In conclusion, Sam should use Asymmetric encryption to secure his e-commerce site, as it will provide a simple security solution that does not require each customer to have an individual key.
