Encryption Decryption Question:
What is the McEliece Cryptosystem?

Answer:
The McEliece cryptosystem is a public-key encryption algorithm based on algebraic coding theory. The system uses a class of error-correcting codes, known as the Goppa codes, for which fast decoding algorithms exist. The basic idea is to construct a Goppa code as the private key and disguise it as a general linear code, which is the public key. The general linear code cannot be easily decoded unless the corresponding private matrix is known.
