After computing the SHA for the ‘P’ to obtain hash value, and encrypt it with

the private key of MR-BS, both original ‘P’ and D

b

(H) are sent to the N-RS. N-RS

will receive the message, decrypt it using the MR-BS public key to obtain the origi-

nal hash value of the ‘P’ computed by N-RS. N-RS will compute the hash value of

‘P’ using SHA and compare both hash values. When both values match, it shows

authenticity and nonrepudiation of this message. To obtain the critical information

that is encrypted by the public key of MR-BS, only N-RS has the corresponding

private key to decrypt this information, which ensures the secrecy of the message.
