One Batch Authentication Scheme For Telemedicine

Telemedicine is a new medical model for 21 st century, which is the use of telecommunication and information technologies in order to provide clinical health care at a distance. Patients who live in isolated communities and remote regions can be seen by a doctor or specialist, who can acknowledge patients’ clinical health status and even provide an accurate and complete examination with the patients’ medical information, while the patient may not have to travel or wait the normal distances or times like those from conventional hospital or GP visits. Due to the sensitive medical privacy, critical care and emergency situations, a large volume of data need to be transmitted and the resources constraints of portable medical devices, telemedicine communications have the crucial requirements of fast authentication and encryption/decryption. From the telemedical applications of cryptology model, we extract the authentication components, construct a more secure and efficient authentication scheme for bulk SEBAPTM protocol, meeting the information integrity, authentication, confidentiality, non-repudiation, resistant to forgery and to DoS attacks. Experimental evaluation of data, as opposed to batch certification scheme UBAPV2 G based on the standard DSA, SEBAPTM with certification of signatures of higher efficiency, lower latency, and strong ability against DoS attacks, is particularly suitable for real-time communication and processing power, storage, and network bandwidth-constrained environments.Specific results are as follows:1. On the premise of security, to maximize the improvement of the algorithm can improve the computational efficiency, we replace the modular inverse operation using modular multiplication operations in the signature calculation, obtain a more efficient batch certification of signature algorithms SEBAP.2. SEBAP improves signature calculation of a DSA variant, fills the forgery attack, while for forgery attack in UBAPV2 G, we use "double buffer" structural design, make this type of forgery attacks impossible.3. The use of packet filtering mechanisms to protect against DoS attacks, that is, the algorithm uses disjoint collection of disaggregated data, packs the collection to a batch processing instead of time-consuming One-by-One process, thereby reducing the bulk verification algorithm for recursive operations, effectively fights DoS attacks. In addition, the data packet filtering mechanism has a filtering effect of corruption data, which has strong signature forgery resilience.4. A measured assessment of the SEBAPTM bulks approval option. Evaluation results showed that SEBAP signature costs approximately 87.4% of the DSA; SEBAPTM authentication latency of batch programme accounts for 64.2% One-by-One; Under the DoS attacks, packet filtering-enabled authentication latency accounts for approximately 52.7% packet filtering is not enabled, consequently, packet filtering mechanism against DoS attacks and forgery attacks have a positive effect.
