Why not flip random bits of the encrypted message for additional security? (hybrid system)

Your proposal boils down to introducing a second key, and using it to perform a simple xor encryption. If you have so little confidence in the first algorithm that you would not use it as-is, you ...

Getting the slope of a public key given its x and y coordinates

Since you are talking about ECC and we are in a crypto stack exchange, I suppose you define your elliptic curve over a finite field, lets say $\mathbb{F}_q$. Here is a tool that lets you plot elliptic ...

"Appendable" encryption scheme

This is a function of stream ciphers that are not plaintext aware - which is usually the case. These ciphers have a random access property which allows you to encrypt / decrypt any byte in the stream. ...

Why not flip random bits of the encrypted message for additional security? (hybrid system)

Before sending the message, person A flips all the bits whose indexes are in $s$. E.g. if $s={1,2,3}$ the bits number $1,2,3$ would be flipped. This is not secure. You might say that only half of the ...
