![]() ![]() It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor.įor technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. ![]() This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. In cryptography, encryption is the process of encoding information. A simple illustration of public-key cryptography, one of the most widely used forms of encryption
