Exchange of information between computer networks requires a secure
communications channel to prevent and monitor unauthorized access,
modification and denial of the computer network. To address this growing
problem, security experts sought ways to advance the integrity of data
transmission. Security Attacks compromises the security and hence hybrid
cryptographic algorithms have been proposed to achieve safe service in the
proper manner, such as user authentication and data confidentiality. Data
security and authenticity are achieved using these algorithms. Moreover, to
improve the strength and cover each algorithm’s weaknesses, a new security
algorithm can be designed using the combination of different cryptographic
techniques. This design uses Digital Signature Algorithm (DSA) for
authentic key generation, Data Encryption Standard (DES) for key
scheduling, and Advanced Encryption Standard (AES) and Rivest–Schamir–
Adleman Algorithm (RSA) in encrypting data. This new security algorithm
has been proposed for improved security and integrity by integration of these
cryptographic techniques.

1. INTRODUCTION
The science of encrypting and decrypting data using mathematics is called cryptography. It enables
users to store private information and send it across mediums susceptible to attacks of hackers thereby
reducing the compromise in data security. This makes it hard for any unauthorized interference to garble with
sensitive data.
Cryptography works with the use of algorithms. A cipher or cryptographic algorithm is a
mathematical function used in the process of encryption and decryption process. To hide confidential
information, data or message can be encrypted using keys generated from a word, a number, or a phrase. This
plaintext is encrypted to different ciphertexts using different keys. The strength of the cryptographic
algorithm and the secrecy of the key greatly affects the security of encrypted data [1].
However, there are still persisting threats due to the familiarity of these cryptographic techniques
added with its simplicity to potential attackers. Present problems include Brute-force attacks, low encryption
strength, and insufficient randomness in key generation [2]. Moreover, data privacy is challenged since
passwords can be also be stolen especially when logged in an unsecure network. The system’s vulnerability
to attacks must be less probable as a function of the security parameter. In this paper, we address this matters

by proposing a mixed encryption algorithm by combining the presented cryptography techniques and utilize
their strengths and as much as possible, reduce the weakness of one technique with that of another.
2. RESEARCH METHOD
2.1. Basic Principles involved in the Proposed Scheme
2.1.1. DSA (Digital Signature Algorithm)
Authentication and authenticity are ensued using Digital Signature Algorithm [3]. A parameter
required is a secret key x such that it satisfies 0 < x < q in computing the private and public keys for a single
user. Get the public key using the formula: y=gx
mod p. To solve for the modular exponentiations h(p − 1)
/q
mod p and gx
mod p, exponentiation by squaring can be applied [4].
2.1.2. DES Key Scheduling
The key scheduling of the DES separates the 56-bit key is into two 28-bit halves; wherein each half
is treated separately. These halves are rotated left by one or two bits per each successive round as specified in
Table 1. Then, 48 subkey bits are selected by Permuted Choice 2 (PC-2) — 24 bits from the left half, and 24
from the right. There are varying sets of bits in each subkey because of the rounds; each bit is used in about
14 out of the 16 subkeys [5].
Table 1. Shifts for each round in DES Key Scheduling
Round 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Shift 1 1 2 2 2 2 2 2 1 2 2 2 2 2 2 1
2.1.3. AES (Advanced Encryption Standard) Algorithm
AES algorithm is a symmetric block cipher, which offers better security and efficiency than DES [3]
in message encryption, is a widely-used algorithm primarily executed using a software. It has low memory
requirements making it appropriate for fast usage in some constrained environment. AES encryption process
is operated in a 4 x Nb matrix (also known as state) where Nb is equivalent to the quotient of the data block
length and 32 [6]. Encryption comprises the following steps [7], [8]:
a. AddRoundKey
Each byte in the state matrix is XORed with the Roundkey value is XORed.
b. SubBytes
In this stage, each byte is substituted with its equivalent byte as defined from a look-up table. Refer
to Table 2(a) for the look-up table during encryption and Table 2(b) during decryption.
Table 2. AES SubByte Transformation Table (a) & Inverse Subbyte Transformation (b) [3]
(a) (b)
c. ShiftRows
With an incrementing number of rows, a cyclic shift to the left of each byte is operated in each
column of the matrix.
d. Mixed Columns

Yielding a four-term polynomial by treating the matrix column by column and multiplying with
another polynomial as stated in the standard of over GF (28
) comprises this step.
2.1.4. RSA
RSA algorithm is a public key encryption algorithm, utilizes a public key and a private key. The
keys appear as pairs, and the corresponding key must be utilized for encryption and decryption
operation [4], [9].
a) Confidential prime numbers p and q are chosen in the same order of magnitude.
b) Compute for n = pɸq, ɸ(n) = (p-1) (q-1), where ɸ(n) is the Euler function value of n.
c) Pick an integer e to satisfy 1 <e<ɸ(n), ɸ(n)
d) Generate a decryption key d as follows: (e×d) modɸ(n) = 1
Encryption c = me
mod n
Decryption m = cd
mod n
The encryption keys are e and n while d and n are the decryption keys. The ciphertext is m while c is
the decrypted ciphertext. The public keys are (e, n) while (d, n) constitute the private key, prime numbers p
and q should be discarded.
2.2. Proposed Hybrid Algorithm Architecture
It is desired to communicate data with high security. At present, various types of cryptographic
algorithms provide high security to information on controlled networks. These algorithms are required to
provide data security and users authenticity. This new security protocol has been designed for better security
using a combination of DSA key generation and DES key scheduling with AES subByte Transformation and
RSA encryption.

As shown in Figure 1, the proposed algorithm requires a passphrase shared by both the sender and
receiver to securely authenticate data exchange. The passphrase is encrypted using the first phase of Digital
Signature Algorithm (DSA) in which different users in the system share the same algorithm parameters. In
the encryption stage, the passphrase is encrypted to ensure that hackers may not intrude and interfere with the
transmission. The encrypted public key (y) is then converted into binary and n keys are derived using DES
key Scheduling. Those keys are XORed with the plain text, concealed using AES subByte Transformation, to
securely hide the original plain text. The data is then complemented, converted to decimal and encrypted with
RSA to get the ciphertext for more confidentiality. During the decryption stage, same steps are applied to the
receiver in which they must also input passphrase, encrypted with DSA, key generate with DES to allow
access to data. The keys will then be XORed to the decrypted ciphertext with RSA to gain the AES subByte
equivalent. Plaintext will be recovered using the table for subByte Transformation.
This proposal, DARE (DSA/DES – AES – RSA Encryption) algorithm is composed of three
components: Key generation which uses DSA and DES; data encryption and decryption which uses AES and
RSA.
2.3. Key Generation
The Key generator works as follows:
a. Alice inputs a passphrase of up to n characters (l1 l2 l3 … ln) which is converted to its binary equivalent,
bitwise XORed, gray coded, and converted to decimal form
b. Alice picks a perfect square not greater than the decimal and deducts it from the number such that its
difference is an odd prime number. Let this difference be p1.
c. Alice chooses a number q1 such that it is a prime factor of p1-1 and a number h’ such that it is less than
p1-1.
d. Alice computes g=h’(p1-1)/q1 (mod p)
e. Alice chooses a private key x.
f. Alice computes y = gx
(mod p1).
g. Alice converts y to binary uses the table for round shifts in DES key scheduling which results to k0 up to
kn.
2.4. Encryption
The encryption algorithm works as follows: to encrypt a message m to Bob under Alice’ public key
(k0 up to kn) Alice picks a prime number p2 such that p2 > (largest ASCII equivalent of the message) and a
random number q.
a. Alice calculates n= p2 * q2 and ɸ(n) = (p2-1) * (q2-1).
b. Alice chooses e such that (0 <e< ɸ(n)).
c. Alice computes for d - the inverse modulo of e. using Euclidian Algorithm e * d mod ɸ(n))= 1
d. Alice publishes her public key (e, n) and (d, n)
e. Alice converts the message into its HEX equivalent.
f. Alice uses the table for SubByte Transformation in AES to hide the message and converts them into
binary.
g. Alice uses her keys to bitwise XOR it with her binary message.
h. Alice computes its 1’s complement and converts it to decimal form. Let it be m.
i. Alice uses the c = me (mod n) to encrypt m.
2.5. Decryption
The decryption algorithm works as follows: to decrypt a ciphertext {c1, c2, c3 … cn} with keys public
keys (k0 - kn, e, d, n)
a. Bob inputs the same shared passphrase for authentication which allows him to access the ciphertext.
b. Using the public key d, Bob calculates the message: m = cd
mod n
c. Bob converts the m1 to mn from decimal to binary form and get the 1’s complement of each.
d. Bob uses the keys k0 to kn in Bitwise XORing each of the 1’s complemented m.
e. Bob then uses the inverse SubByte Transformation table in AES to recover the hex equivalent of the
message.
f. The hexes are then converted to ASCII equivalent to decrypt the plain text.

8. Convert it to equivalent message.
The original plaintext message is recovered to be:
Waltz, nymph, for quick jigs vex Bud.
Results show that the proposal is doable since the original message has been recovered from
following the steps included in the section. In this proposal, both the sender and receiver must input a
passphrase which undergoes encryption in DSA. The encrypted password is then shifted with rounds using
DES key scheduling. Failure of inputting the correct passphrase would result in a different message since the
keys used in encrypting and decrypting the message obtained from the passphrase. This functionality
strengthens data authenticity of this proposal. Moreover, hiding data using the SubByte Transformation in
AES reinforces the encryption strength of RSA.
4. CONCLUSION
In this paper, we proposed a robust protocol using DSA and DES for key generation and scheduling
and AES and RSA for encryption and decryption of information. The combination of these different
cryptography algorithms delivers a maximized efficiency, amending or compensating each other’s
deficiencies.
Moreover, it offers a more protected exchange of data since both ends have an encrypted passphrase
required to decrypt the message. Therefore, it requires more effort to the hackers to discover the message
itself because they have to decrypt the passphrase first. This new hybrid protocol yields a strong
cryptosystem together with a secure key encryption management system ensuring all security goals.
