A problem with asymmetric encryption, however, is that it is slower than symmetric encryption. It requires far more processing power to both encrypt and decrypt the content of the message. To use asymmetric encryption, there must be a way for people to discover other public keys.
Since for any matrix A, (kA)â² = kAâ², it follows that 1/2 (A + Aâ²) is symmetric matrix and 1/2 (A â Aâ²) is skew symmetric matrix. Thus, any square matrix can be expressed as the sum of a symmetric and a skew symmetric matrix. Example Express the matrix as the sum of a symmetric and a skew symmetric matrix. Solution Here Let Thus P = 1/2 (B + Bâ²)is a symmetric matrix. Also, let Then Thus Q = 1/2 (B â Bâ²)is a skew symmetric matrix.
